The main object of +this investigation was to find, if possible, a means of distinguishing +beers and ales made entirely from malt from those made from malt +together with other cereal products, such as rice, corn, and cerealin. + +It was concluded, after looking into the literature, that in order to +accomplish this purpose it would be necessary to collect a series of +samples made from the various raw materials ordinarily used and make a +study of the effect of these raw materials upon the composition of the +finished product. + +The investigation seemed desirable for the reason that practically all +of the existing data related to foreign beers, in the preparation of +which a type of malt was used entirely different from that ordinarily +used in the production of American beers. Furthermore, very few of the +existing data relating either to foreign or domestic beers were based +upon samples concerning which exact information was available in regard +to the raw materials used in the wort. + + +METHOD OF UNDERTAKING THE INVESTIGATION. + +It was felt that it would be wholly unsatisfactory to make this +investigation by means of laboratory brewings on a small scale, as the +results thus obtained would not show the true conditions, because it is +not possible in the laboratory to duplicate exactly the mashing or +fermenting processes actually used in a commercial way. It was decided, +therefore, to attempt, with the cooperation of several breweries, to +make this study under the exact conditions prevailing in commercial +plants. Access was secured to several breweries making different types +of products from various kinds of raw materials, under such conditions +that it was possible to obtain a complete history of the beer through +its various stages to the finished product. One of the writers (Riley) +watched the method of manufacture during its whole process and obtained +samples of the product at the various stages of manufacture. Thus, it +was possible to procure finished samples with practically the same +degree of certainty, as regards knowledge of composition and history, as +would have been the case had they been prepared in the laboratory. + +In three different breweries manufacturing a wide range of products +samples of the wort and beer were obtained in this manner, the entire +process of manufacture being studied in detail. A record showing the +kind and amount of raw materials placed in the mash and in the cooker +was made of the samples collected from these three breweries. A record +also was kept of the time and temperature of each operation until the +mash was ready to run into the kettle. The filtering and sparging[1] of +the mash, the time of boiling in the kettle, the amount of hops added +and the point at which they were added, and the break[2] of the wort +were all noted. After the wort had been pumped from the kettle its +course was followed through the hop jack[3] over the coolers to the +settling tank. The specific gravity or Balling[4] of the original wort, +the temperature at which the product was pitched,[5] the aeration of the +wort, the kind and amount of yeast added, as well as the time and +maximum temperature of the primary fermentation, also were noted. The +course of the beer through the storage vats, chip casks, and filters to +the racks was watched, and samples of the wort and of the beer in its +various stages of production were collected and examined. + +[Footnote 1: Washing the grains with hot water to remove the extract or +valuable constituents as completely as possible.] + +[Footnote 2: Precipitation and uniting, in the form of flakes, of the +coagulable albuminoids, leaving the liquid clear.] + +[Footnote 3: A filtering tank.] + +[Footnote 4: Percentage of solids in the liquor according to the Balling +hydrometer.] + +[Footnote 5: Pitching is the operation of adding the yeast to the wort.] + + +METHODS OF ANALYSIS. + +The methods of analysis used were those given in Bulletin 107, revised +(U. S. Dept. Agr., Bur. Chem.), pages 90-94, with the exception that the +determination of phosphoric acid was made by the method used in +fertilizer analysis (ibid., pp. 2-5), destroying the organic material in +the beer by digestion with strong sulphuric acid and nitric acid and +determining the phosphoric acid finally by the optional volumetric +method (ibid., p. 4). The uranium acetate method given for beers was not +used, for the reason that it was found to be exceedingly difficult to +obtain accurate results on dark-colored beers.[1] + +[Footnote 1: Riley, in his report to the Association of Official +Agricultural Chemists for the year 1913, stated that the method giving +the most uniform results was that of ashing the beer with an excess of +standard calcium acetate, and that while the moist combustion method in +the hands of those familiar with it gave satisfactory results, the +various collaborators working with the method did not get as uniform +results as with the method of ashing with calcium acetate. J. Assoc. +Off. Agr. Chemists 1 (1915), 138-143.] + +It was found in the estimation of dextrin by the Sachsse-Allihn method +(ibid., p. 91) that there is an error in the method of calculation of +the amount of dextrose formed from the amount of maltose in the original +beer. Instead of multiplying the amount of maltose in the original beer +by the factor 0.9, it should be multiplied by the factor 1.053, as 1 +gram of anhydrous maltose yields, on hydrolysis, 1.053 grams of +dextrose. The product is the quantity which should be subtracted from +the total amount of dextrose found after hydrolysis. The extract in the +beer was determined by use of the tables of Schultz and Ostermann +(ibid., pp. 209-213). The same methods were used in the analyses of the +worts as were used in the examination of the beers. + + +RESULTS OF ANALYSIS. + +Tables I to IV contain the results of the analyses of the worts and +finished fermented products obtained at the various breweries where this +investigation was conducted, arranged so as to show readily the changes +which took place during fermentation and, in a few cases, the changes +which took place during storage. The results are all given in terms of +grams per 100 cc, so that a direct comparison of the quantities of any +particular ingredient in a definite volume of material may be made. The +comparison of the grams per 100 cc of an ingredient in the wort, with +the grams per 100 cc in the finished fermented product, is based on the +assumption that there is no appreciable change in the volume of the wort +during fermentation. + +In Table I are given the results of the analyses of 7 malt worts and the +beers produced from them. Table II contains the results of the analyses +of 2 malt-and-rice worts and 2 malt-and-corn worts, and the beers +produced from them. In Table III are given the results of the analyses +of 4 porter worts and the finished porters produced from them. The +results of the analyses of 9 ale worts and the finished ales are shown +in Table IV. In these four tables the extract in the original wort has +been calculated by multiplying the alcohol (expressed in terms of grams +per 100 cc) by 2, and adding to the product the extract of the beer, +porter, or ale (expressed in terms of grams per 100 cc). In the porter +and ale worts a percentage of dextrose had been added as brewer's sugar. +Since dextrose reduces more copper than does maltose in the +determination of the sugars, in order to obtain the true percentage of +total sugars it was necessary to calculate the amount of copper reduced +by the known amount of dextrose present, and then to calculate the +amount of maltose. The results thus obtained are given in Tables III and +IV under the heading "Reducing sugars as anhydrous maltose." + + +TABLE I.--_Analyses of all-malt worts and of the beers made from them._ +

By dividing alcohol into loss in solids +there was secured a factor which makes possible the estimation of the +solids in the original wort, provided that alcohol and extract are +known. This factor also shows the yield of alcohol for a given amount of +solids disappearing during fermentation. It has been found in the case +of the beers that this factor averages 2.14, while in the case of the +ales it averages 2.12, making an average for all of the products of +2.13. This clearly shows that in the yield of alcohol for a given amount +of fermentable solids there is no appreciable difference between top +fermentation products, such as ales, and bottom fermentation products, +such as beers. + +A marked difference in loss in solids is shown, however, when we compare +the beers with the ales. In the case of the beers we find there is +practically no difference between the loss in solids and the loss in +sugar, while in the case of the porters and ales there is a very +appreciable difference. The difference between the loss in solids and +the loss in sugar is only 0.04 per cent for all of the beers; while in +the case of the porters and ales the difference varies from 1.47 per +cent to 2.65 per cent, with an average of 1.96 per cent. These figures +clearly show that in the case of the porters and ales there has been +some material other than sugar fermented. Unfortunately, the +determination of dextrin was not made in all of the worts, so that the +actual decrease in dextrin can be shown only in a few cases. But in +those cases where we have the actual results the difference between loss +in solids and the loss in sugar compares very closely with the actual +amount of dextrin disappearing during fermentation. + + +DEVELOPMENT OF ACIDS DURING FERMENTATION. + +A comparison of the amounts of volatile and fixed acids in the worts and +in the finished beers shows that normally there is no appreciable +development of volatile acid during fermentation and only a slight +increase in the fixed acid. This increase in fixed acid averages in the +case of the beers 0.049 per cent, while in the case of the ales the +increase averages 0.103 per cent. + + +DECREASE IN PROTEIN, ASH, AND PHOSPHORIC ACID. + +A general study of the preceding tables will show that there is an +appreciable loss of protein, ash, and phosphoric acid during the +fermentation. Table VI has been prepared to show the average loss during +fermentation of the various classes of worts with respect to their +protein, ash, and phosphoric acid contents. + + +TABLE VI.--_Average loss during fermentation._ + ++---------------------------+----------+----------+-----------+ +| | Protein. | Ash. |Phosphoric | +| Kind of wort. | | | acid. | ++---------------------------+----------+----------+-----------+ +| | Grams per| Grams per| Grams per | +| | 100 cc. | 100 cc. | 100 cc. | ++---------------------------+----------+----------+-----------+ +|Beer worts (all-malt) | 0.209 | 0.017 | 0.015 | +|Beer worts (malt and rice) | .210 | .045 | .014 | +|Beer worts (malt and corn) | .168 | .014 | .013 | +|Porter worts | .213 | .031 | .017 | +|Ale worts | .275 | .029 | .019 | ++---------------------------+----------+----------+-----------+ + + +The results given in Table VI show a great similarity in the changes in +all of the products, as there is about the same amount of loss of +protein, ash, and phosphoric acid in the beer, ale, and porter worts. +There does not appear to be any appreciable loss, however, of either +protein or phosphoric acid during the storage or aging period as is +shown by the few samples which we have analyzed after storage. This is +practically in agreement with the experiment of Bertschinger,[1] whose +results show only a very slight increase in alcohol and loss of sugar +during the storage period. + +[Footnote 1: Z. angew.

++-------+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+ + +[Footnote 1: Brewer's scale.] + + +In the results given under brewery No. 1, a beer made entirely from malt +is compared with a beer made from 65 per cent of malt and 35 per cent of +cerealin, and with a beer made from 60 per cent of malt and 40 per cent +of corn, in all of which the same quality of malt was used. + +In the case of brewery No. 2, a beer made entirely from malt and a beer +made from 80 per cent of malt and 20 per cent of rice are given, in both +of which the same quality of malt was used. + +Under brewery No. 3 are given determinations for ales prepared from 80 +per cent of malt and 20 per cent of cerealin; 78 per cent of malt and 22 +per cent of cerealin; 75 per cent of malt and 25 per cent of cerealin; +and 65 per cent of malt, 28 per cent of cerealin, and 7 per cent of +brewer's sugar. The same quality of malt was used in all of these brews, +but the brews were of different strengths. + +Table VII is given practically in two parts, the first part showing the +actual results obtained by the analysis of the finished beer or ale and +the second part showing protein, ash, and phosphoric acid calculated to +the basis of a uniform wort containing 15 per cent of solids. + +Taking into consideration the actual results obtained upon the beers and +ales, it will be seen in the case of brewery No. 1 that the three beers +vary in composition to a considerable degree. Especially is this +variation marked in regard to the protein, ash, and phosphoric acid +contents, which exhibit a marked decrease approximately in direct +proportion to the amount of cerealin or corn substituted for malt. The +same condition is apparent in the case of the products made in brewery +No. 2, the beer made from 80 per cent of malt and 20 per cent of rice +showing a material reduction in protein, ash, and phosphoric acid. In +brewery No. 3, however, a somewhat different condition is noted. +Unfortunately, there is no all-malt product of this brewery to compare +with the brews made from a portion of cerealin or from cerealin and +brewer's sugar. It will be noted, however, that when the actual results +obtained on the finished products of this brewery are compared with +those of the all-malt brews of breweries Nos. 1 and 2, they do not +clearly show a reduction of protein and ash as might be expected. For +example, in the case of one of the samples of the ale made with 25 per +cent of cerealin and 75 per cent of malt (sample No. 29512-B), the +percentage of protein is 0.65 and of the ash 0.266. The percentages of +protein and ash for the three samples of this ale represented by Nos. +29512-B, 29514-B, and 29519-B are higher than were found in any of the +all-malt products of the first two breweries under consideration. This, +however, can be readily explained when it is considered that in the case +of brewery No. 2 in the all-malt beers (sample No. 22017-D) only 58 +pounds of malt were used in the preparation of a barrel of beer +containing 31 gallons; while in the case of sample No. 29512-B there +were used, in preparing a barrel of similar capacity, 68 pounds of malt +and 23 pounds of cerealin. That is, in the second product there is, in +the same volume of liquid, the extractive material from 68 pounds of +malt and 23 pounds of cerealin, while in the first product there is +present the extractive material from only 58 pounds of malt. Since the +analysis is made upon the finished liquid it is evident that the +percentage composition of any particular ingredient should be very much +larger in the second product because of the very much larger amount of +material used in its preparation. It is apparent, therefore, that no +direct comparison can be made between the percentage composition of +these different brews in order to determine the effects of the raw +materials upon their composition. + +The most satisfactory way to have tested this question of the effect of +raw materials on the finished product would have been to make a series +of worts with exactly the same percentage of solids, some of pure malt +and others of mixtures of pure malt and corn, rice, and cerealin; then a +direct comparison between the results would have shown the effects of +these various materials. This method was impracticable because it was +necessary to take the brews as actually made under varying commercial +conditions. The object sought can be accomplished, however, by +calculating the results of these analyses either to the basis of dry +material in the original wort or by calculating them to the basis of a +wort with constant water content. It was decided to calculate all of the +results to the basis of a wort containing 15 per cent of solids, as this +would give a uniform basis for comparison and would be approximately an +average wort. The method employed in calculating the various beers and +ales to this uniform basis was as follows: + +The percentage of solids in the original wort was calculated by +multiplying the percentage by weight of alcohol by 2 and adding the +percentage by weight of extract. The result for an ordinary beer would +be about 12 per cent, while in the case of a very heavy ale it might be +as high as 18 or 20 per cent. The actual percentages of protein, ash, +and phosphoric acid found by analysis were then calculated to the basis +of a uniform wort containing 15 per cent of solids. This was the method +used for preparing the second part of this table. A study of this +portion of the table shows the actual effects of the various substitutes +used for malt on the composition of the fermented product. For instance, +the first of the all-malt beers from brewery No. 2 (22017-D) showed in +the analysis of the original product a protein percentage of 0.603, an +ash percentage of 0.206, and a phosphoric acid percentage of 0.079. When +calculated to the basis of a wort containing 15 per cent of solids +instead of 12.72 per cent (the actual percentage of solids in the wort +from which it was made), it gave the following percentages: Protein, +0.712; ash, 0.243; and phosphoric acid, 0.093. In the case of brewery +No. 3, sample No. 29512-B, where the original analysis of the product +showed 0.650 per cent of protein, 0.266 of ash, and 0.057 of phosphoric +acid, it will be found that when this product is calculated to the basis +of a wort of 15 per cent of solids instead of a wort of 19.52 (the +actual percentage of solids in the wort in this case) the percentage of +ash is 0.204, of protein 0.499, and of phosphoric acid 0.044. A +comparison of these results shows that in the protein, ash, and +phosphoric acid there has been a material reduction below the figures +found upon the all-malt beer, due to the presence of the 25 per cent of +cerealin. A study of these results, calculated to the basis of 15 per +cent of solids in the wort, shows very clearly that the general effect +of the substitution of cerealin, brewer's sugar, rice, and corn is to +reduce the content of ash, protein, and phosphoric acid. + +It is evident from the results here given that the most important things +to be considered in judging the nature of the raw materials used in the +preparation of a beer are the quantities of protein, phosphoric acid, +and ash; as the other constituents present in the finished beer are more +or less variable, the quantities present depending upon the methods of +mashing and fermentation. + +Table VIII contains a summary of results giving the ash, protein, and +phosphoric acid in all of the finished products of known composition +which were examined, calculated to the basis of a uniform wort of 15 per +cent of solids. + + +TABLE VIII.--_Summary of the results of analyses (showing ash, protein, +and phosphoric acid determinations) in all finished products of known +composition, calculated to the basis of a uniform wort containing 15 per +cent of solids._ + ++-----------------------------+----------+-----+-----------+------------+ +|Raw materials. |Products. |Ash. | Protein | Phos- | +| | | |(N × 6.25).| phoric | +| | | | | Acid (as | +| | | | |P_{2}O_{5}).| ++-----------------------------+----------+-----+-----------+------------+ +|Malt |Beers: 21 |Per | Per | Per | +| | samples |cent.| cent. | cent. | +| | Maximum |0.336| 1.079 | 0.143 | +| | Minimum | .230| .701 | .087 | +| | Average | .275| .870 | .109 | ++-----------------------------+----------+=====+===========+============+ +| | | | | | +|80 per cent malt | | | | | +| and 20 per cent rice |Beer | .202| .517 | .073 | +|66 per cent malt | | | | | +| and 34 per cent rice | do | .198| .555 | .084 | +|62 per cent malt | | | | | +| and 38 per cent rice | do | .205| .488 | .061 | +|55 per cent malt | | | | | +| and 45 per cent rice | do | .148| .380 | .077 | +|50 per cent malt | | | | | +| and 50 per cent rice | do | .167| .351 | .056 | +| +----------+-----+-----------+------------+ +| | Maximum | .205| .555 | .084 | +| +----------+=====+===========+============+ +|70 per cent malt | | | | | +| and 30 per cent corn |Beer | .199| .343 | .057 | +| Do | do | .188| .367 | .065 | +|68 per cent malt | | | | | +| and 32 per cent corn | do | .150| .461 | .057 | +| Do | do | .181| .466 | .062 | +| Do | do | .164| .459 | .056 | +|60 per cent malt | | | | | +| and 40 per cent corn | do | .215| .563 | .074 | +| Do | do | .188| .593 | .076 | +| Do | do | .223| .597 | .074 | +|45 per cent malt | | | | | +| and 55 per cent corn | do | .145| .347 | .057 | +| +----------+-----+-----------+------------+ +| | Maximum | .223| .597 | .076 | +| +----------+=====+===========+============+ +|65 per cent malt | | | | | +| and 35 per cent cerealin |Beer | .192| .483 | .057 | +|80 per cent malt | | | | | +| and 20 per cent cerealin |Ale | .215| .480 | .051 | +|78 per cent malt | | | | | +| and 22 per cent cerealin | do | .176| .455 | .050 | +| Do | do | .169| .476 | .045 | +| Do | do | .181| .502 | .040 | +|75 per cent malt | | | | | +| and 25 per cent cerealin | do | .204| .499 | .044 | +| Do | do | .196| .509 | .044 | +| Do | do | .191| .502 | .043 | +|65 per cent malt, | | | | | +| 7 per cent brewer's sugar, | | | | | +| and 28 per cent cerealin | do | .185| .409 | .037 | +| Do | do | .175| .443 | .040 | +| Do | do | .166| .427 | .041 | ++-----------------------------+----------+-----+-----------+------------+ +| | Maximum | .213| .509 | .051 | ++-----------------------------+----------+-----+-----------+------------+ + + +A study of the results given in Table VIII shows that in the case of +American beers the all-malt beers are higher in ash, protein, and +phosphoric acid than are any of the beers made from a mixed mash of malt +and other cereals. The difference is sufficiently marked to make it +possible to draw a rather sharp line between the all-malt beers and the +beers made from the present commercial mixtures. Take, for instance, the +beers made from mixtures of malt and rice in which the proportion of +rice varies from 20 to 50 per cent. It will be seen that in none of +these samples is the ash, phosphoric acid, or protein so high as the +minimum found in the all-malt beers. The same will be seen in the case +of the malt-and-corn beers. In none of the malt-and-corn beers is the +ash, protein, or phosphoric acid so high as the minimum found in the +all-malt beers, and the same is true of the mixtures of malt and +cerealin and of malt, brewer's sugar, and cerealin. This shows clearly +that the commercial beers made in this country from malt and malt +substitutes can be distinguished readily from all-malt beers. + +When the average composition of the 21 all-malt beers examined is taken +into consideration it will be seen that there is a very sharp line of +demarcation between the all-malt and the malt, rice, and corn products. +From the figures which were obtained upon American beers it would seem +that protein as a rule is more sharply reduced by the addition of malt +substitutes than is the ash or the phosphoric acid, although where corn +or cerealin is used there is a very marked reduction in the amount of +phosphoric acid. It would appear, therefore, from the results of this +investigation that in the consideration of American beers it will be +comparatively easy to draw a line between beers made solely from malt +and those made from mixtures of malt with rice, corn, and other +substitutes. + +This conclusion is not entirely in agreement with the results which have +been obtained by others upon foreign beers, in the preparation of which +low protein barleys have been used. Joseph Race[1] has reported some +interesting results of an investigation carried on for the same purpose +as that for which this particular investigation was undertaken; that is, +to distinguish between all-malt beers and those made from substitutes. +His results do not show as sharp a reduction of the protein, but he +found in his all-malt beers a very much lower percentage of total +protein than was found in the malt beers of this country. He did +observe, however, a material reduction of the phosphoric acid due to the +use of substitutes. Unfortunately, he made his determination of +phosphoric acid in the ash, and while he reports a marked difference +between the phosphoric acid content of the malt beers and those made +from substitutes, his total figures for phosphoric acid are much lower +than those reported in this bulletin. For this reason the figures for +total phosphoric acid given by him are not at all comparable with those +determined by the moist combustion method, by the uranium acetate +method, or by the method of ashing with calcium acetate.[2] + +[Footnote 1: J. Soc. Chem. Ind., 27 (1908), 544-547.] + +[Footnote 2: Riley, in his report to the Association of Official +Agricultural Chemists for the year 1913, showed that a large proportion +of the phosphoric acid was ordinarily lost when the beer was directly +ashed (J. Assoc. Off. Agr. Chemists, 1 (1915), 138-143). For this +reason, in comparing the amount of phosphoric acid given in the +literature on beers, it is very essential to know the method used for +determining the phosphoric acid.] + + +The same fact observed by Race, namely, that foreign beers are of low +protein content, is shown very clearly in the published literature on +European beers in general. König[3] gives the following results of +analyses made by himself and H. Weigmann of two all-malt beers, +calculated to the basis of a wort containing 15 per cont of solids: + ++-----------------------------+-----------+-----------+-----------+ +|Beer and percentage of wort. | Protein. | Ash. |Phosphoric | +| | | | acid. | ++-----------------------------+-----------+-----------+-----------+ +| | Per cent. | Per cent. | Per cent. | +|Pure malt beer: | | | | +| 12 percent wort | 0.548 | 0.259 | 0.098 | +| 14 percent wort | .457 | .214 | .076 | ++-----------------------------+-----------+-----------+-----------+ + + +From these results of König it will be seen that the protein content of +these beers is considerably less than that of the beers examined by the +writers. As the phosphoric acid and ash results, however, are +practically the same as in American beers, it might be expected that the +use of substitutes in place of the low-protein malt would not show so +sharp a reduction of the protein as was found by the authors, although +one would expect a reduction in phosphoric acid and ash similar to that +found in American beers. This is confirmed by the results obtained by +Race. + +Robert Wahl[4] made parallel brewings of a high-protein barley and a +low-protein barley, and from these obtained two beers which, when +calculated to a uniform wort with 15 per cent of solids, showed a total +protein in the beer made from the low-protein malt of 0.734 per cent, +and in the beer made from the high-protein malt 1.041 per cent. This +clearly indicates that where a beer is made from high-protein barley, as +is the case with practically all of the beers made in this country,[5] +the reduction in protein by the use of substitutes will be a valuable +index to the true nature of the product. This, when taken in connection +with the reduction of phosphoric acid brought about by the use of +substitutes, gives two factors of value in judging American beers, to +determine whether or not substitutes have been used; while in the case +of beers made from low-protein barley there is practically only one +factor, namely, the reduction of phosphoric acid. + +[Footnote 3: König, F. J., Chemie der Menschlichen Nahrungs- und Genussmittel, +4th ed., v. 1, p. 1154. Berlin, 1903.] + +[Footnote 4: Am. Brewers' Rev., 18 (1904), 339.] + +[Footnote 5: Wahl, Robert. _In_ Am. Brewers' Rev., 29 (1915), 316-317.] + + +After this rather extensive study had been made at the three breweries, +the investigation was extended to include breweries in various sections +of the country where different types of raw materials were used. A +special effort was made to obtain authentic samples of practically all +of the malt beers made in this country and also a large series of +malt-and-rice and malt-and-corn beers.

All of these results show +practically the same condition noted in the other samples of malt beer; +that is, a comparatively high protein and phosphoric acid content as +compared with beers made in part from rice or corn. These malt beers +show figures considerably higher in protein than those given in the +literature for all-malt beers made from the low-protein malt of Europe. + + +TABLE IX.--_Analyses of all-malt American beers._ + +Column Headings: + +A: Sample No. +B: Alcohol. +C: Extract (Schultz and Ostermann). +D: Extract in original wort (calculated). +E: Degree of fermentation. +F: Total acid as lactic. +G: Volatile acid as acetic. +H: Reducing sugars as anhydrous maltose. +I: Dextrin. +J: Protein (N × 6.25). +K: Ash. +L: Phosphoric acid (as P_{2}O_{5}). +M: Undetermined. +N: Polarimeter. +O: Color (Lovibond) in 1/4-inch cell. +P: Calculated to basis of wort with 15 per cent of solids. +Q: Protein (N × 6.25). +R: Ash. +S: Phosphoric acid (as P_{2}O_{5}). + ++-------+------+-----+-----+-----+-----+-----+-----+-----+-----+ +| | | | | | | | | | | +| | | | | | | | | | | +| A | B | C | D | E | F | G | H | I | J | ++-------+------+-----+-----+-----+-----+-----+-----+-----+-----+ +| | Per | | | | | | | | | +| | cent.| | | | | | | | | +| | by | Per | Per | | Per | Per | Per | Per | Per | +| |weight|cent.|cent.| |cent.|cent.|cent.|cent.|cent.| +|22017-D| 3.83 | 5.06|12.72|60.22|0.214|0.001| 1.32| 2.30|0.603| +|22018-D| 3.90 | 5.06|12.86|60.65| .223| .002| 1.34| 2.03| .606| +|22020-D| 3.69 | 5.12|12.50|59.04| .234| .002| 1.57| 2.20| .630| +|22021-D| 3.63 | 5.54|12.80|56.72| .219| .001| 1.82| 2.15| .626| +|16289-C| 3.00 | 5.88|11.88|50.50| .228| .003| 1.33| 2.68| .752| +|16299-C| 2.84 | 6.02|11.70|48.55| .232| .012| 1.38| 2.77| .724| +|20714-D| 3.07 | 5.80|11.94|51.42| .241| .012| 1.45| 2.64| .721| +|20715-D| 2.95 | 5.77|11.67|50.56| .228| .009| 1.43| 2.67| .725| +|23571-E| 3.68 | 4.44|11.80|62.45| .232| .010| 1.06| 1.67| .653| +|23585-E| 3.60 | 5.04|12.24|58.82| .277| .005| 1.36| 1.81| .811| +|23528-E| 3.28 | 6.36|12.92|50.80| .384| .016| 1.62| 2.74| .905| +|23533-E| 3.41 | 5.48|12.30|55.45| .232| .008| 1.48| 2.44| .612| +|23537-E| 3.80 | 7.26|14.86|51.35| .250| .012| 2.51| 2.95| .802| +|23588-E| 3.16 | 6.11|12.43|50.84| .250| .008| 1.93| 2.41| .797| +|23538-E| 3.13 | 6.61|12.77|48.24| .250| .009| 2.13| 2.82| .612| +|23589-E| 3.35 | 6.21|12.91|51.90| .178| .017| 1.78| 2.87| .627| +|23539-E| 3.22 | 6.63|13.27|48.53| .312| .017| 2.18| 2.58| .778| +|23540-E| 3.93 | 6.77|14.63|53.73| .348| .007| 2.64| 1.87|1.010| +|23590-E| 3.48 | 5.45|12.41|56.09| .375| .010| 2.21| 1.48| .892| +|23541-E| 3.12 | 5.06|11.30|55.22| .259| .004| 1.69| 1.27| .777| +|14004-H| 3.07 | 5.55|11.69|52.54| .223| .013| 1.59| 2.64| .615| ++-------+------+-----+-----+-----+-----+-----+-----+-----+-----+ + ++-------+-----+-----+-----+-------+-------+-----------------+ +| | | | | | | P | +| | | | | | |-----+-----+-----+ +| A | K | L | M | N | O | Q | R | S | ++-------+-----+-----+-----+-------+-------+-----+-----+-----+ +| | | | | | | | | | +| | | | | | | | | | +| | Per | Per | Per |Degrees|Degrees| Per | Per | Per | +| |cent.|cent.|cent.| V. | [1] |cent.|cent.|cent.| +|22017-D|0.206|0.079| 0.63| ... | 12 |0.712|0.243|0.093| +|22018-D| .199| .077| .88| ... | 13 | .701| .230| .090| +|22020-D| .203| .080| .52| ... | 11 | .756| .244| .096| +|22021-D| .205| .081| .74| ... | 10 | .734| .240| .095| +|16289-C| .242| .081| .88| +36.8 | ... | .950| .306| .102| +|16299-C| .237| .088| .91| +40.0 | ... | .932| .304| .113| +|20714-D| .225| .089| .76| +36.4 | 3 | .906| .283| .112| +|20715-D| .213| .088| .73| +36.0 | 4 | .932| .274| .113| +|23571-E| .229| .096| .83| +21.6 | ... | .830| .291| .122| +|23585-E| .257| .102| .80| +23.2 | 6 | .994| .315| .124| +|23528-E| .239| .123| .86| +37.2 | 13 |1.051| .277| .143| +|23533-E| .200| .086| .75| +33.6 | 3 | .747| .244| .105| +|23537-E| .228| .098| .77| +44.0 | 14 | .809| .230| .099| +|23588-E| .208| .086| .76| +37.2 | 4 | .952| .251| .104| +|23538-E| .225| .087| .82| +43.6 | 9 | .719| .264| .102| +|23589-E| .204| .075| .73| +40.0 | 7 | .729| .237| .087| +|23539-E| .248| .097| .84| +38.8 | 22 | .879| .280| .109| +|23540-E| .324| .129| .93| +34.0 | 18 |1.035| .332| .132| +|23590-E| .264| .109| .60| +25.6 | 7 |1.079| .319| .132| +|23541-E| .253| .087| 1.07| +20.0 | 4 |1.031| .336| .115| +|14004-H| .207| .072| .49| ... | 5 | .789| .266| .092| ++-------+-----+-----+-----+-------+-------+-----+-----+-----+ + +[Footnote 1: Brewer's scale.] + + +In Tables X and XI are given the results for beers made from malt and +rice and from malt and corn.

Brewer's scale.] + + +The data reported in Tables X, XI, and XII give the results of analyses +of commercial American beers obtained from various breweries in +different parts of the United States as these beers are found on the +market at the present time; hence, they are of general value for the +purpose of showing the composition of American beers. These data also +are of considerable interest when we compare them with data relating to +American beers published by the department in 1887.[1] A comparison of +these two sets of figures shows that beers made at the present time have +a much lower percentage of alcohol and are made from a wort containing a +much lower percentage of solids than beers made a generation ago. The +average of 28 samples examined and reported in 1887 in the publication +cited[1] showed an average alcohol content of 4.63 per cent by weight +and solids in the original wort of 14.79 per cent, while the average of +72 beers representing the products now on the market showed an average +of 3.52 per cent by weight of alcohol and solids in the original wort of +12.50 per cent. This is a reduction of 1.11 per cent by weight of +alcohol and 2.23 per cent of solids in the original wort. + +[Footnote 1: U. S. Dept. Agr., Div. Chem., Bul. 13, 1887, pt. 3, p. 282.] + + +CONCLUSIONS. + +The all-malt beers made in this country contain higher percentages of +protein than the all-malt beers made in Europe, owing to the use in this +country of a barley high in protein. + +The use of rice, corn or corn products, and brewer's sugar as +substitutes for malt reduces the content of protein, ash, and phosphoric +acid in the finished beer. + +This difference, as regards the protein, ash, and phosphoric acid, is a +sufficient basis for distinguishing the all-malt beers made in this +country from those containing the commercial mixtures of rice, corn, +cerealin, and brewer's sugar. + +It is necessary to calculate analytical results to the basis of a common +wort in order to interpret them properly. + + * * * * * + + ADDITIONAL COPIES + OF THIS PUBLICATION MAY BE PROCURED FROM + THE SUPERINTENDENT OF DOCUMENTS + GOVERNMENT PRINTING OFFICE + WASHINGTON, D.

Information about Donations to the Project Gutenberg +Literary Archive Foundation + +Project Gutenberg-tm depends upon and cannot survive without wide +spread public support and donations to carry out its mission of +increasing the number of public domain and licensed works that can be +freely distributed in machine readable form accessible by the widest +array of equipment including outdated equipment. Many small donations +($1 to $5,000) are particularly important to maintaining tax exempt +status with the IRS. + +The Foundation is committed to complying with the laws regulating +charities and charitable donations in all 50 states of the United +States. Compliance requirements are not uniform and it takes a +considerable effort, much paperwork and many fees to meet and keep up +with these requirements. We do not solicit donations in locations +where we have not received written confirmation of compliance. To +SEND DONATIONS or determine the status of compliance for any +particular state visit http://pglaf.org + +While we cannot and do not solicit contributions from states where we +have not met the solicitation requirements, we know of no prohibition +against accepting unsolicited donations from donors in such states who +approach us with offers to donate. + +International donations are gratefully accepted, but we cannot make +any statements concerning tax treatment of donations received from +outside the United States. U.S. laws alone swamp our small staff. + +Please check the Project Gutenberg Web pages for current donation +methods and addresses.

The main object of +this investigation was to find, if possible, a means of distinguishing +beers and ales made entirely from malt from those made from malt +together with other cereal products, such as rice, corn, and cerealin.</p> + +<p>It was concluded, after looking into the literature, that in order to +accomplish this purpose it would be necessary to collect a series of +samples made from the various raw materials ordinarily used and make a +study of the effect of these raw materials upon the composition of the +finished product.</p> + +<p>The investigation seemed desirable for the reason that practically all +of the existing data related to foreign beers, in the preparation of +which a type of malt was used entirely different from that ordinarily +used in the production of American beers. Furthermore, very few of the +existing data relating either to foreign or domestic beers were based +upon samples concerning which exact information was available in regard +to the raw materials used in the wort.<span class='pagenum'> + <a name="Page_2" id="Page_2">[Pg 2]</a></span></p> + + +<h2><a name="Meth1" id="Meth1"></a><br /><br />METHOD OF UNDERTAKING THE INVESTIGATION.</h2> + +<p>It was felt that it would be wholly unsatisfactory to make this +investigation by means of laboratory brewings on a small scale, as the +results thus obtained would not show the true conditions, because it is +not possible in the laboratory to duplicate exactly the mashing or +fermenting processes actually used in a commercial way. It was decided, +therefore, to attempt, with the cooperation of several breweries, to +make this study under the exact conditions prevailing in commercial +plants. Access was secured to several breweries making different types +of products from various kinds of raw materials, under such conditions +that it was possible to obtain a complete history of the beer through +its various stages to the finished product. One of the writers (Riley) +watched the method of manufacture during its whole process and obtained +samples of the product at the various stages of manufacture. Thus, it +was possible to procure finished samples with practically the same +degree of certainty, as regards knowledge of composition and history, as +would have been the case had they been prepared in the laboratory.</p> + +<p>In three different breweries manufacturing a wide range of products +samples of the wort and beer were obtained in this manner, the entire +process of manufacture being studied in detail. A record showing the +kind and amount of raw materials placed in the mash and in the cooker +was made of the samples collected from these three breweries. A record +also was kept of the time and temperature of each operation until the +mash was ready to run into the kettle. The filtering and + <span style="white-space: nowrap">sparging<a name="FNanchor_1_1" id="FNanchor_1_1"></a> + <a href="#Footnote_1_1" class="fnanchor">[1]</a></span> of +the mash, the time of boiling in the kettle, the amount of hops added +and the point at which they were added, and the + <span style="white-space: nowrap">break<a name="FNanchor_2_2" id="FNanchor_2_2"></a> + <a href="#Footnote_2_2" class="fnanchor">[2]</a></span> of the wort +were all noted. After the wort had been pumped from the kettle its +course was followed through the hop + <span style="white-space: nowrap">jack<a name="FNanchor_3_3" id="FNanchor_3_3"></a> + <a href="#Footnote_3_3" class="fnanchor">[3]</a></span> over the coolers to the +settling tank.

S. Dept. Agr., Bur. Chem.), pages 90-94, with the exception that the +determination of phosphoric acid was made by the method used in +fertilizer analysis (ibid., pp. 2-5), destroying the organic material in +the beer by digestion with strong sulphuric acid and nitric acid and +determining the phosphoric acid finally by the optional volumetric +method (ibid., p. 4). The uranium acetate method given for beers was not +used, for the reason that it was found to be exceedingly difficult to +obtain accurate results on dark-colored + <span style="white-space: nowrap">beers.<a name="FNanchor_1_6" id="FNanchor_1_6"></a></span> + <a href="#Footnote_1_6" class="fnanchor">[1]</a></p> + +<div class="footnote"><p><a name="Footnote_1_6" id="Footnote_1_6"></a><a href="#FNanchor_1_6"> + <span class="label">[1]</span></a> Riley, in his report to the Association of Official +Agricultural Chemists for the year 1913, stated that the method giving +the most uniform results was that of ashing the beer with an excess of +standard calcium acetate, and that while the moist combustion method in +the hands of those familiar with it gave satisfactory results, the +various collaborators working with the method did not get as uniform +results as with the method of ashing with calcium acetate. J. Assoc. +Off. Agr. Chemists 1 (1915), 138-143.</p></div> + +<p>It was found in the estimation of dextrin by the Sachsse-Allihn method +(ibid., p. 91) that there is an error in the method of calculation of +the amount of dextrose formed from the amount of maltose in the original +beer. Instead of multiplying the amount of maltose in the original beer +by the factor 0.9, it should be multiplied by the factor 1.053, as 1 +gram of anhydrous maltose yields, on hydrolysis, 1.053 grams of +dextrose. The product is the quantity which should be subtracted from +the total amount of dextrose found after hydrolysis. The extract in the +beer was determined by use of the tables of Schultz and Ostermann +(ibid., pp. 209-213). The same methods were used in the analyses of the +worts as were used in the examination of the beers.</p> + +<h2><a name="Reslt" id="Reslt"></a><br /><br />RESULTS OF ANALYSIS.</h2> + +<p>Tables I to IV contain the results of the analyses of the worts and +finished fermented products obtained at the various breweries where this +investigation was conducted, arranged so as to show readily the changes +which took place during fermentation and, in a few cases, the changes +which took place during storage. The results are all given in terms of +grams per 100 cc, so that a direct comparison of the quantities of any +particular ingredient in a definite volume of material may be made. The +comparison of the grams per 100 cc of an ingredient in the wort, with +the grams per 100 cc in the finished fermented product, is based on the +assumption that there is no appreciable change in the volume of the wort +during fermentation.</p> + +<p>In Table I are given the results of the analyses of 7 malt worts and the +beers produced from them. Table II contains the results of the analyses +of 2 malt-and-rice worts and 2 malt-and-corn worts, and <span class='pagenum'> + <a name="Page_4" id="Page_4">[Pg 4]</a></span>the beers +produced from them. In Table III are given the results of the analyses +of 4 porter worts and the finished porters produced from them. The +results of the analyses of 9 ale worts and the finished ales are shown +in Table IV. In these four tables the extract in the original wort has +been calculated by multiplying the alcohol (expressed in terms of grams +per 100 cc) by 2, and adding to the product the extract of the beer, +porter, or ale (expressed in terms of grams per 100 cc). In the porter +and ale worts a percentage of dextrose had been added as brewer's sugar. +Since dextrose reduces more copper than does maltose in the +determination of the sugars, in order to obtain the true percentage of +total sugars it was necessary to calculate the amount of copper reduced +by the known amount of dextrose present, and then to calculate the +amount of maltose. The results thus obtained are given in Tables III and +IV under the heading "Reducing sugars as anhydrous maltose."</p> + +<p><span class='pagenum'><a name="Page_5" id="Page_5">[Pg 5]</a></span></p>

in solids between the wort and the finished +fermented product, the loss in sugar, the yield of alcohol, the loss in +solids divided by the alcohol, and the difference between the loss in +solids and the loss in sugar. By dividing alcohol into loss in solids +there was secured a factor which makes possible the estimation of the +solids in the original wort, provided that alcohol and extract are +known. This factor also shows the yield of alcohol for a given amount of +solids disappearing during fermentation. It has been found in the case +of the beers that this factor averages 2.14, while in the case of the +ales it averages 2.12, making an average for all of the products of +2.13. This clearly shows that in the yield of alcohol for a given amount +of fermentable solids there is no appreciable difference between top +fermentation products, such as ales, and bottom fermentation products, +such as beers.</p> + +<p>A marked difference in loss in solids is shown, however, when we compare +the beers with the ales. In the case of the beers we find there is +practically no difference between the loss in solids and the loss in +sugar, while in the case of the porters and ales there is a very +appreciable difference. The difference between the loss in solids and +the loss in sugar is only 0.04 per cent for all of the beers; while in +the case of the porters and ales the difference varies from 1.47 per +cent to 2.65 per cent, with an average of 1.96 per cent. These figures +clearly show that in the case of the porters and ales there has been +some material other than sugar fermented. Unfortunately, the +determination of dextrin was not made in all of the worts, so that the +actual decrease in dextrin can be shown only in a few cases. But in +those cases where we have the actual results the difference between loss +in solids and the loss in sugar compares very closely with the actual +amount of dextrin disappearing during fermentation.</p> + +<h4><br /><br />DEVELOPMENT OF ACIDS DURING FERMENTATION.</h4> + +<p>A comparison of the amounts of volatile and fixed acids in the worts and +in the finished beers shows that normally there is no appreciable +development of volatile acid during fermentation and only a slight +increase in the fixed acid.

a beer made from 65 per cent of malt and 35 per cent of +cerealin, and with a beer made from 60 per cent of malt and 40 per cent +of corn, in all of which the same quality of malt was used.</p> + +<p>In the case of brewery No. 2, a beer made entirely from malt and a beer +made from 80 per cent of malt and 20 per cent of rice are given, in both +of which the same quality of malt was used.</p> + +<p>Under brewery No. 3 are given determinations for ales prepared from 80 +per cent of malt and 20 per cent of cerealin; 78 per cent of malt and 22 +per cent of cerealin; 75 per cent of malt and 25 per cent of cerealin; +and 65 per cent of malt, 28 per cent of cerealin, and 7 per cent of +brewer's sugar. The same quality of malt was used in all of these brews, +but the brews were of different strengths.</p> + +<p>Table VII is given practically in two parts, the first part showing the +actual results obtained by the analysis of the finished beer or ale and +the second part showing protein, ash, and phosphoric acid calculated to +the basis of a uniform wort containing 15 per cent of solids.</p> + +<p>Taking into consideration the actual results obtained upon the beers and +ales, it will be seen in the case of brewery No. 1 that the three beers +vary in composition to a considerable degree. Especially is this +variation marked in regard to the protein, ash, and phosphoric acid +contents, which exhibit a marked decrease approximately in direct +proportion to the amount of cerealin or corn substituted for malt. The +same condition is apparent in the case of the products made in brewery +No. 2, the beer made from 80 per cent of malt and 20 per cent of rice +showing a material reduction in protein, ash, and phosphoric acid. In +brewery No. 3, however, a somewhat different condition is noted. +Unfortunately, there is no all-malt product of this brewery to compare +with the brews made from a portion of cerealin or from cerealin and +brewer's sugar. It will be noted, however, that when the actual results +obtained on the finished products of this brewery are compared with +those of the all-malt brews of breweries Nos. 1 and 2, they do not +clearly show a reduction of protein and ash as might be expected. For +example, in the case of one of the samples of the ale made with 25 per +cent of cerealin and 75 per cent of malt (sample No. 29512-B), the +percentage of protein is 0.65 and of the ash 0.266. The percentages of +protein and ash for the three samples of this ale represented by Nos. +29512-B, 29514-B, and 29519-B are higher than were found in any of the +all-malt products of the first two breweries under consideration. This, +however, can be readily explained when it is considered that in the case +of brewery No. 2 in the all-malt beers (sample No. 22017-D) only 58 +pounds of malt were used in the preparation of a barrel of beer +containing 31 gallons; while in the case of sample No. 29512-B there +were used, in preparing a barrel of similar capacity, 68 pounds of malt +and 23 pounds of cerealin. That is, in the second product there is, in +the same volume of liquid, the extrac<span class='pagenum'> + <a name="Page_14" id="Page_14">[Pg 14]</a></span>tive material from 68 pounds of +malt and 23 pounds of cerealin, while in the first product there is +present the extractive material from only 58 pounds of malt. Since the +analysis is made upon the finished liquid it is evident that the +percentage composition of any particular ingredient should be very much +larger in the second product because of the very much larger amount of +material used in its preparation. It is apparent, therefore, that no +direct comparison can be made between the percentage composition of +these different brews in order to determine the effects of the raw +materials upon their composition.</p> + +<p>The most satisfactory way to have tested this question of the effect of +raw materials on the finished product would have been to make a series +of worts with exactly the same percentage of solids, some of pure malt +and others of mixtures of pure malt and corn, rice, and cerealin; then a +direct comparison between the results would have shown the effects of +these various materials. This method was impracticable because it was +necessary to take the brews as actually made under varying commercial +conditions. The object sought can be accomplished, however, by +calculating the results of these analyses either to the basis of dry +material in the original wort or by calculating them to the basis of a +wort with constant water content. It was decided to calculate all of the +results to the basis of a wort containing 15 per cent of solids, as this +would give a uniform basis for comparison and would be approximately an +average wort. The method employed in calculating the various beers and +ales to this uniform basis was as follows:</p> + +<p>The percentage of solids in the original wort was calculated by +multiplying the percentage by weight of alcohol by 2 and adding the +percentage by weight of extract. The result for an ordinary beer would +be about 12 per cent, while in the case of a very heavy ale it might be +as high as 18 or 20 per cent. The actual percentages of protein, ash, +and phosphoric acid found by analysis were then calculated to the basis +of a uniform wort containing 15 per cent of solids. This was the method +used for preparing the second part of this table. A study of this +portion of the table shows the actual effects of the various substitutes +used for malt on the composition of the fermented product. For instance, +the first of the all-malt beers from brewery No. 2 (22017-D) showed in +the analysis of the original product a protein percentage of 0.603, an +ash percentage of 0.206, and a phosphoric acid percentage of 0.079. When +calculated to the basis of a wort containing 15 per cent of solids +instead of 12.72 per cent (the actual percentage of solids in the wort +from which it was made), it gave the following percentages: Protein, +0.712; ash, 0.243; and phosphoric acid, 0.093. In the case of brewery +No. 3, sample No. 29512-B, where the original analysis of the product +showed 0.650 per cent of protein, 0.266 of ash, and 0.057 of phosphoric +acid, it will be found that when this product is calculated to the basis +of a wort of 15 per <span class='pagenum'><a name="Page_15" id="Page_15">[Pg 15]</a></span> + cent of solids instead of a wort of 19.52 (the +actual percentage of solids in the wort in this case) the percentage of +ash is 0.204, of protein 0.499, and of phosphoric acid 0.044. A +comparison of these results shows that in the protein, ash, and +phosphoric acid there has been a material reduction below the figures +found upon the all-malt beer, due to the presence of the 25 per cent of +cerealin. A study of these results, calculated to the basis of 15 per +cent of solids in the wort, shows very clearly that the general effect +of the substitution of cerealin, brewer's sugar, rice, and corn is to +reduce the content of ash, protein, and phosphoric acid.</p> + +<p>It is evident from the results here given that the most important things +to be considered in judging the nature of the raw materials used in the +preparation of a beer are the quantities of protein, phosphoric acid, +and ash; as the other constituents present in the finished beer are more +or less variable, the quantities present depending upon the methods of +mashing and fermentation.</p> + +<p>Table VIII contains a summary of results giving the ash, protein, and +phosphoric acid in all of the finished products of

all-malt beers are higher in ash, protein, and +phosphoric acid than are any of the beers made from a mixed mash of malt +and other cereals. The difference is sufficiently marked to make it +possible to draw a rather sharp line between the all-malt beers and the +beers made from the present commercial mixtures. Take, for instance, the +beers made from mixtures of malt and rice in which the proportion of +rice varies from 20 to 50 per cent. It will be seen that in none of +these samples is the ash, phosphoric acid, or protein so high as the +minimum found in the all-malt beers. The same will be seen in the case +of the malt-and-corn beers. In none of the malt-and-corn beers is the +ash, protein, or phosphoric acid so high as the minimum found in the +all-malt beers, and the same is true of the mixtures of malt and +cerealin and of malt, brewer's sugar, and cerealin. This shows clearly +that the commercial beers made in this country from malt and malt +substitutes can be distinguished readily from all-malt beers.</p> + +<p>When the average composition of the 21 all-malt beers examined is taken +into consideration it will be seen that there is a very sharp line of +demarcation between the all-malt and the malt, rice, and corn products. +From the figures which were obtained upon American beers it would seem +that protein as a rule is more sharply reduced by the addition of malt +substitutes than is the ash or the phosphoric acid, although where corn +or cerealin is used there is a very marked reduction in the amount of +phosphoric acid. It would appear, therefore, from the results of this +investigation that in the consideration of American beers it will be +comparatively easy to draw a line between beers made solely from malt +and those made from mixtures of malt with rice, corn, and other +substitutes.</p> + +<p>This conclusion is not entirely in agreement with the results which have +been obtained by others upon foreign beers, in the preparation of which +low protein barleys have been used. Joseph Race<a name="FNanchor_1_9" id="FNanchor_1_9"></a> + <a href="#Footnote_1_9" class="fnanchor">[1]</a> has reported some +interesting results of an investigation carried on for the same purpose +as that for which this particular investigation was undertaken; that is, +to distinguish between all-malt beers and those made from substitutes. +His results do not show as sharp a reduction of the protein, but he +found in his all-malt beers a very much lower percentage of total +protein than was found in the malt beers of this country. He did +observe, however, a material reduction of the phosphoric acid due to the +use of substitutes.

These results are of +value, however, in showing the general composition of American beers +made from the ordinary commercial mixtures and clearly indicate that by +taking into consideration the ash, protein, and phosphoric acid content +it is practicable to distinguish commercial beers made in this country +from malt and malt substitutes from beers made from malt alone.</p> + +<p><span

Information about the Mission of Project Gutenberg-tm + +Project Gutenberg-tm is synonymous with the free distribution of +electronic works in formats readable by the widest variety of computers +including obsolete, old, middle-aged and new computers. It exists +because of the efforts of hundreds of volunteers and donations from +people in all walks of life. + +Volunteers and financial support to provide volunteers with the +assistance they need, is critical to reaching Project Gutenberg-tm's +goals and ensuring that the Project Gutenberg-tm collection will +remain freely available for generations to come. In 2001, the Project +Gutenberg Literary Archive Foundation was created to provide a secure +and permanent future for Project Gutenberg-tm and future generations. +To learn more about the Project Gutenberg Literary Archive Foundation +and how your efforts and donations can help, see Sections 3 and 4 +and the Foundation web page at http://www.pglaf.org. + + +Section 3. Information about the Project Gutenberg Literary Archive +Foundation + +The Project Gutenberg Literary Archive Foundation is a non profit +501(c)(3) educational corporation organized under the laws of the +state of Mississippi and granted tax exempt status by the Internal +Revenue Service. The Foundation's EIN or federal tax identification +number is 64-6221541. Its 501(c)(3) letter is posted at +http://pglaf.org/fundraising.

Newby + Chief Executive and Director + gbnewby@pglaf.org + + +Section 4. Information about Donations to the Project Gutenberg +Literary Archive Foundation + +Project Gutenberg-tm depends upon and cannot survive without wide +spread public support and donations to carry out its mission of +increasing the number of public domain and licensed works that can be +freely distributed in machine readable form accessible by the widest +array of equipment including outdated equipment. Many small donations +($1 to $5,000) are particularly important to maintaining tax exempt +status with the IRS. + +The Foundation is committed to complying with the laws regulating +charities and charitable donations in all 50 states of the United +States. Compliance requirements are not uniform and it takes a +considerable effort, much paperwork and many fees to meet and keep up +with these requirements. We do not solicit donations in locations +where we have not received written confirmation of compliance. To +SEND DONATIONS or determine the status of compliance for any +particular state visit http://pglaf.org + +While we cannot and do not solicit contributions from states where we +have not met the solicitation requirements, we know of no prohibition +against accepting unsolicited donations from donors in such states who +approach us with offers to donate. + +International donations are gratefully accepted, but we cannot make +any statements concerning tax treatment of donations received from +outside the United States. U.S. laws alone swamp our small staff. + +Please check the Project Gutenberg Web pages for current donation +methods and addresses. Donations are accepted in a number of other +ways including checks, online payments and credit card donations. +To donate, please visit: http://pglaf.org/donate + + +Section 5. General Information About Project Gutenberg-tm electronic +works. + +Professor Michael S. Hart is the originator of the Project Gutenberg-tm +concept of a library of electronic works that could be freely shared +with anyone. For thirty years, he produced and distributed Project +Gutenberg-tm eBooks with only a loose network of volunteer support. + + +Project Gutenberg-tm eBooks are often created from several printed +editions, all of which are confirmed as Public Domain in the U.S. +unless a copyright notice is included. Thus, we do not necessarily +keep eBooks in compliance with any particular paper edition. + + +Most people start at our Web site which has the main PG search facility: + + http://www.gutenberg.org + +This Web site includes information about Project Gutenberg-tm, +including how to make donations to the Project Gutenberg Literary +Archive Foundation, how to help produce our new eBooks, and how to +subscribe to our email newsletter to hear about new eBooks. + + +</pre> + +</body> +</html> diff --git a/25050-h/images/logo.png b/25050-h/images/logo.png Binary files differnew file mode 100644

The main object of +this investigation was to find, if possible, a means of distinguishing +beers and ales made entirely from malt from those made from malt +together with other cereal products, such as rice, corn, and cerealin. + +It was concluded, after looking into the literature, that in order to +accomplish this purpose it would be necessary to collect a series of +samples made from the various raw materials ordinarily used and make a +study of the effect of these raw materials upon the composition of the +finished product. + +The investigation seemed desirable for the reason that practically all +of the existing data related to foreign beers, in the preparation of +which a type of malt was used entirely different from that ordinarily +used in the production of American beers. Furthermore, very few of the +existing data relating either to foreign or domestic beers were based +upon samples concerning which exact information was available in regard +to the raw materials used in the wort. + + +METHOD OF UNDERTAKING THE INVESTIGATION. + +It was felt that it would be wholly unsatisfactory to make this +investigation by means of laboratory brewings on a small scale, as the +results thus obtained would not show the true conditions, because it is +not possible in the laboratory to duplicate exactly the mashing or +fermenting processes actually used in a commercial way. It was decided, +therefore, to attempt, with the cooperation of several breweries, to +make this study under the exact conditions prevailing in commercial +plants. Access was secured to several breweries making different types +of products from various kinds of raw materials, under such conditions +that it was possible to obtain a complete history of the beer through +its various stages to the finished product. One of the writers (Riley) +watched the method of manufacture during its whole process and obtained +samples of the product at the various stages of manufacture. Thus, it +was possible to procure finished samples with practically the same +degree of certainty, as regards knowledge of composition and history, as +would have been the case had they been prepared in the laboratory. + +In three different breweries manufacturing a wide range of products +samples of the wort and beer were obtained in this manner, the entire +process of manufacture being studied in detail. A record showing the +kind and amount of raw materials placed in the mash and in the cooker +was made of the samples collected from these three breweries. A record +also was kept of the time and temperature of each operation until the +mash was ready to run into the kettle. The filtering and sparging[1] of +the mash, the time of boiling in the kettle, the amount of hops added +and the point at which they were added, and the break[2] of the wort +were all noted. After the wort had been pumped from the kettle its +course was followed through the hop jack[3] over the coolers to the +settling tank. The specific gravity or Balling[4] of the original wort, +the temperature at which the product was pitched,[5] the aeration of the +wort, the kind and amount of yeast added, as well as the time and +maximum temperature of the primary fermentation, also were noted. The +course of the beer through the storage vats, chip casks, and filters to +the racks was watched, and samples of the wort and of the beer in its +various stages of production were collected and examined. + +[Footnote 1: Washing the grains with hot water to remove the extract or +valuable constituents as completely as possible.] + +[Footnote 2: Precipitation and uniting, in the form of flakes, of the +coagulable albuminoids, leaving the liquid clear.] + +[Footnote 3: A filtering tank.] + +[Footnote 4: Percentage of solids in the liquor according to the Balling +hydrometer.] + +[Footnote 5: Pitching is the operation of adding the yeast to the wort.] + + +METHODS OF ANALYSIS. + +The methods of analysis used were those given in Bulletin 107, revised +(U. S. Dept. Agr., Bur. Chem.), pages 90-94, with the exception that the +determination of phosphoric acid was made by the method used in +fertilizer analysis (ibid., pp. 2-5), destroying the organic material in +the beer by digestion with strong sulphuric acid and nitric acid and +determining the phosphoric acid finally by the optional volumetric +method (ibid., p. 4). The uranium acetate method given for beers was not +used, for the reason that it was found to be exceedingly difficult to +obtain accurate results on dark-colored beers.[1] + +[Footnote 1: Riley, in his report to the Association of Official +Agricultural Chemists for the year 1913, stated that the method giving +the most uniform results was that of ashing the beer with an excess of +standard calcium acetate, and that while the moist combustion method in +the hands of those familiar with it gave satisfactory results, the +various collaborators working with the method did not get as uniform +results as with the method of ashing with calcium acetate. J. Assoc. +Off. Agr. Chemists 1 (1915), 138-143.] + +It was found in the estimation of dextrin by the Sachsse-Allihn method +(ibid., p. 91) that there is an error in the method of calculation of +the amount of dextrose formed from the amount of maltose in the original +beer. Instead of multiplying the amount of maltose in the original beer +by the factor 0.9, it should be multiplied by the factor 1.053, as 1 +gram of anhydrous maltose yields, on hydrolysis, 1.053 grams of +dextrose. The product is the quantity which should be subtracted from +the total amount of dextrose found after hydrolysis. The extract in the +beer was determined by use of the tables of Schultz and Ostermann +(ibid., pp. 209-213). The same methods were used in the analyses of the +worts as were used in the examination of the beers. + + +RESULTS OF ANALYSIS. + +Tables I to IV contain the results of the analyses of the worts and +finished fermented products obtained at the various breweries where this +investigation was conducted, arranged so as to show readily the changes +which took place during fermentation and, in a few cases, the changes +which took place during storage. The results are all given in terms of +grams per 100 cc, so that a direct comparison of the quantities of any +particular ingredient in a definite volume of material may be made. The +comparison of the grams per 100 cc of an ingredient in the wort, with +the grams per 100 cc in the finished fermented product, is based on the +assumption that there is no appreciable change in the volume of the wort +during fermentation. + +In Table I are given the results of the analyses of 7 malt worts and the +beers produced from them. Table II contains the results of the analyses +of 2 malt-and-rice worts and 2 malt-and-corn worts, and the beers +produced from them. In Table III are given the results of the analyses +of 4 porter worts and the finished porters produced from them. The +results of the analyses of 9 ale worts and the finished ales are shown +in Table IV. In these four tables the extract in the original wort has +been calculated by multiplying the alcohol (expressed in terms of grams +per 100 cc) by 2, and adding to the product the extract of the beer, +porter, or ale (expressed in terms of grams per 100 cc). In the porter +and ale worts a percentage of dextrose had been added as brewer's sugar. +Since dextrose reduces more copper than does maltose in the +determination of the sugars, in order to obtain the true percentage of +total sugars it was necessary to calculate the amount of copper reduced +by the known amount of dextrose present, and then to calculate the +amount of maltose. The results thus obtained are given in Tables III and +IV under the heading "Reducing sugars as anhydrous maltose." + + +TABLE I.--_Analyses of all-malt worts and of the beers made from them._ +

+ + +A study of these tables shows very clearly that during fermentation +marked changes are brought about other than the mere conversion of sugar +into alcohol.

By dividing alcohol into loss in solids +there was secured a factor which makes possible the estimation of the +solids in the original wort, provided that alcohol and extract are +known. This factor also shows the yield of alcohol for a given amount of +solids disappearing during fermentation. It has been found in the case +of the beers that this factor averages 2.14, while in the case of the +ales it averages 2.12, making an average for all of the products of +2.13. This clearly shows that in the yield of alcohol for a given amount +of fermentable solids there is no appreciable difference between top +fermentation products, such as ales, and bottom fermentation products, +such as beers. + +A marked difference in loss in solids is shown, however, when we compare +the beers with the ales. In the case of the beers we find there is +practically no difference between the loss in solids and the loss in +sugar, while in the case of the porters and ales there is a very +appreciable difference. The difference between the loss in solids and +the loss in sugar is only 0.04 per cent for all of the beers; while in +the case of the porters and ales the difference varies from 1.47 per +cent to 2.65 per cent, with an average of 1.96 per cent. These figures +clearly show that in the case of the porters and ales there has been +some material other than sugar fermented. Unfortunately, the +determination of dextrin was not made in all of the worts, so that the +actual decrease in dextrin can be shown only in a few cases. But in +those cases where we have the actual results the difference between loss +in solids and the loss in sugar compares very closely with the actual +amount of dextrin disappearing during fermentation. + + +DEVELOPMENT OF ACIDS DURING FERMENTATION. + +A comparison of the amounts of volatile and fixed acids in the worts and +in the finished beers shows that normally there is no appreciable +development of volatile acid during fermentation and only a slight +increase in the fixed acid. This increase in fixed acid averages in the +case of the beers 0.049 per cent, while in the case of the ales the +increase averages 0.103 per cent. + + +DECREASE IN PROTEIN, ASH, AND PHOSPHORIC ACID. + +A general study of the preceding tables will show that there is an +appreciable loss of protein, ash, and phosphoric acid during the +fermentation. Table VI has been prepared to show the average loss during +fermentation of the various classes of worts with respect to their +protein, ash, and phosphoric acid contents. + + +TABLE VI.--_Average loss during fermentation._ + ++---------------------------+----------+----------+-----------+ +| | Protein. | Ash. |Phosphoric | +| Kind of wort. | | | acid. | ++---------------------------+----------+----------+-----------+ +| | Grams per| Grams per| Grams per | +| | 100 cc. | 100 cc. | 100 cc. | ++---------------------------+----------+----------+-----------+ +|Beer worts (all-malt) | 0.209 | 0.017 | 0.015 | +|Beer worts (malt and rice) | .210 | .045 | .014 | +|Beer worts (malt and corn) | .168 | .014 | .013 | +|Porter worts | .213 | .031 | .017 | +|Ale worts | .275 | .029 | .019 | ++---------------------------+----------+----------+-----------+ + + +The results given in Table VI show a great similarity in the changes in +all of the products, as there is about the same amount of loss of +protein, ash, and phosphoric acid in the beer, ale, and porter worts. +There does not appear to be any appreciable loss, however, of either +protein or phosphoric acid during the storage or aging period as is +shown by the few samples which we have analyzed after storage. This is +practically in agreement with the experiment of Bertschinger,[1] whose +results show only a very slight increase in alcohol and loss of sugar +during the storage period. + +[Footnote 1: Z. angew.

++-------+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+ + +[Footnote 1: Brewer's scale.] + + +In the results given under brewery No. 1, a beer made entirely from malt +is compared with a beer made from 65 per cent of malt and 35 per cent of +cerealin, and with a beer made from 60 per cent of malt and 40 per cent +of corn, in all of which the same quality of malt was used. + +In the case of brewery No. 2, a beer made entirely from malt and a beer +made from 80 per cent of malt and 20 per cent of rice are given, in both +of which the same quality of malt was used. + +Under brewery No. 3 are given determinations for ales prepared from 80 +per cent of malt and 20 per cent of cerealin; 78 per cent of malt and 22 +per cent of cerealin; 75 per cent of malt and 25 per cent of cerealin; +and 65 per cent of malt, 28 per cent of cerealin, and 7 per cent of +brewer's sugar. The same quality of malt was used in all of these brews, +but the brews were of different strengths. + +Table VII is given practically in two parts, the first part showing the +actual results obtained by the analysis of the finished beer or ale and +the second part showing protein, ash, and phosphoric acid calculated to +the basis of a uniform wort containing 15 per cent of solids. + +Taking into consideration the actual results obtained upon the beers and +ales, it will be seen in the case of brewery No. 1 that the three beers +vary in composition to a considerable degree. Especially is this +variation marked in regard to the protein, ash, and phosphoric acid +contents, which exhibit a marked decrease approximately in direct +proportion to the amount of cerealin or corn substituted for malt. The +same condition is apparent in the case of the products made in brewery +No. 2, the beer made from 80 per cent of malt and 20 per cent of rice +showing a material reduction in protein, ash, and phosphoric acid. In +brewery No. 3, however, a somewhat different condition is noted. +Unfortunately, there is no all-malt product of this brewery to compare +with the brews made from a portion of cerealin or from cerealin and +brewer's sugar. It will be noted, however, that when the actual results +obtained on the finished products of this brewery are compared with +those of the all-malt brews of breweries Nos. 1 and 2, they do not +clearly show a reduction of protein and ash as might be expected. For +example, in the case of one of the samples of the ale made with 25 per +cent of cerealin and 75 per cent of malt (sample No. 29512-B), the +percentage of protein is 0.65 and of the ash 0.266. The percentages of +protein and ash for the three samples of this ale represented by Nos. +29512-B, 29514-B, and 29519-B are higher than were found in any of the +all-malt products of the first two breweries under consideration. This, +however, can be readily explained when it is considered that in the case +of brewery No. 2 in the all-malt beers (sample No. 22017-D) only 58 +pounds of malt were used in the preparation of a barrel of beer +containing 31 gallons; while in the case of sample No. 29512-B there +were used, in preparing a barrel of similar capacity, 68 pounds of malt +and 23 pounds of cerealin. That is, in the second product there is, in +the same volume of liquid, the extractive material from 68 pounds of +malt and 23 pounds of cerealin, while in the first product there is +present the extractive material from only 58 pounds of malt. Since the +analysis is made upon the finished liquid it is evident that the +percentage composition of any particular ingredient should be very much +larger in the second product because of the very much larger amount of +material used in its preparation. It is apparent, therefore, that no +direct comparison can be made between the percentage composition of +these different brews in order to determine the effects of the raw +materials upon their composition. + +The most satisfactory way to have tested this question of the effect of +raw materials on the finished product would have been to make a series +of worts with exactly the same percentage of solids, some of pure malt +and others of mixtures of pure malt and corn, rice, and cerealin; then a +direct comparison between the results would have shown the effects of +these various materials. This method was impracticable because it was +necessary to take the brews as actually made under varying commercial +conditions. The object sought can be accomplished, however, by +calculating the results of these analyses either to the basis of dry +material in the original wort or by calculating them to the basis of a +wort with constant water content. It was decided to calculate all of the +results to the basis of a wort containing 15 per cent of solids, as this +would give a uniform basis for comparison and would be approximately an +average wort. The method employed in calculating the various beers and +ales to this uniform basis was as follows: + +The percentage of solids in the original wort was calculated by +multiplying the percentage by weight of alcohol by 2 and adding the +percentage by weight of extract. The result for an ordinary beer would +be about 12 per cent, while in the case of a very heavy ale it might be +as high as 18 or 20 per cent. The actual percentages of protein, ash, +and phosphoric acid found by analysis were then calculated to the basis +of a uniform wort containing 15 per cent of solids. This was the method +used for preparing the second part of this table. A study of this +portion of the table shows the actual effects of the various substitutes +used for malt on the composition of the fermented product. For instance, +the first of the all-malt beers from brewery No. 2 (22017-D) showed in +the analysis of the original product a protein percentage of 0.603, an +ash percentage of 0.206, and a phosphoric acid percentage of 0.079. When +calculated to the basis of a wort containing 15 per cent of solids +instead of 12.72 per cent (the actual percentage of solids in the wort +from which it was made), it gave the following percentages: Protein, +0.712; ash, 0.243; and phosphoric acid, 0.093. In the case of brewery +No. 3, sample No. 29512-B, where the original analysis of the product +showed 0.650 per cent of protein, 0.266 of ash, and 0.057 of phosphoric +acid, it will be found that when this product is calculated to the basis +of a wort of 15 per cent of solids instead of a wort of 19.52 (the +actual percentage of solids in the wort in this case) the percentage of +ash is 0.204, of protein 0.499, and of phosphoric acid 0.044. A +comparison of these results shows that in the protein, ash, and +phosphoric acid there has been a material reduction below the figures +found upon the all-malt beer, due to the presence of the 25 per cent of +cerealin. A study of these results, calculated to the basis of 15 per +cent of solids in the wort, shows very clearly that the general effect +of the substitution of cerealin, brewer's sugar, rice, and corn is to +reduce the content of ash, protein, and phosphoric acid. + +It is evident from the results here given that the most important things +to be considered in judging the nature of the raw materials used in the +preparation of a beer are the quantities of protein, phosphoric acid, +and ash; as the other constituents present in the finished beer are more +or less variable, the quantities present depending upon the methods of +mashing and fermentation. + +Table VIII contains a summary of results giving the ash, protein, and +phosphoric acid in all of the finished products of known composition +which were examined, calculated to the basis of a uniform wort of 15 per +cent of solids. + + +TABLE VIII.--_Summary of the results of analyses (showing ash, protein, +and phosphoric acid determinations) in all finished products of known +composition, calculated to the basis of a uniform wort containing 15 per +cent of solids._ + ++-----------------------------+----------+-----+-----------+------------+ +|Raw materials. |Products. |Ash. | Protein | Phos- | +| | | |(N x 6.25).| phoric | +| | | | | Acid (as | +| | | | |P_{2}O_{5}).| ++-----------------------------+----------+-----+-----------+------------+ +|Malt |Beers: 21 |Per | Per | Per | +| | samples |cent.| cent. | cent. | +| | Maximum |0.336| 1.079 | 0.143 | +| | Minimum | .230| .701 | .087 | +| | Average | .275| .870 | .109 | ++-----------------------------+----------+=====+===========+============+ +| | | | | | +|80 per cent malt | | | | | +| and 20 per cent rice |Beer | .202| .517 | .073 | +|66 per cent malt | | | | | +| and 34 per cent rice | do | .198| .555 | .084 | +|62 per cent malt | | | | | +| and 38 per cent rice | do | .205| .488 | .061 | +|55 per cent malt | | | | | +| and 45 per cent rice | do | .148| .380 | .077 | +|50 per cent malt | | | | | +| and 50 per cent rice | do | .167| .351 | .056 | +| +----------+-----+-----------+------------+ +| | Maximum | .205| .555 | .084 | +| +----------+=====+===========+============+ +|70 per cent malt | | | | | +| and 30 per cent corn |Beer | .199| .343 | .057 | +| Do | do | .188| .367 | .065 | +|68 per cent malt | | | | | +| and 32 per cent corn | do | .150| .461 | .057 | +| Do | do | .181| .466 | .062 | +| Do | do | .164| .459 | .056 | +|60 per cent malt | | | | | +| and 40 per cent corn | do | .215| .563 | .074 | +| Do | do | .188| .593 | .076 | +| Do | do | .223| .597 | .074 | +|45 per cent malt | | | | | +| and 55 per cent corn | do | .145| .347 | .057 | +| +----------+-----+-----------+------------+ +| | Maximum | .223| .597 | .076 | +| +----------+=====+===========+============+ +|65 per cent malt | | | | | +| and 35 per cent cerealin |Beer | .192| .483 | .057 | +|80 per cent malt | | | | | +| and 20 per cent cerealin |Ale | .215| .480 | .051 | +|78 per cent malt | | | | | +| and 22 per cent cerealin | do | .176| .455 | .050 | +| Do | do | .169| .476 | .045 | +| Do | do | .181| .502 | .040 | +|75 per cent malt | | | | | +| and 25 per cent cerealin | do | .204| .499 | .044 | +| Do | do | .196| .509 | .044 | +| Do | do | .191| .502 | .043 | +|65 per cent malt, | | | | | +| 7 per cent brewer's sugar, | | | | | +| and 28 per cent cerealin | do | .185| .409 | .037 | +| Do | do | .175| .443 | .040 | +| Do | do | .166| .427 | .041 | ++-----------------------------+----------+-----+-----------+------------+ +| | Maximum | .213| .509 | .051 | ++-----------------------------+----------+-----+-----------+------------+ + + +A study of the results given in Table VIII shows that in the case of +American beers the all-malt beers are higher in ash, protein, and +phosphoric acid than are any of the beers made from a mixed mash of malt +and other cereals. The difference is sufficiently marked to make it +possible to draw a rather sharp line between the all-malt beers and the +beers made from the present commercial mixtures. Take, for instance, the +beers made from mixtures of malt and rice in which the proportion of +rice varies from 20 to 50 per cent. It will be seen that in none of +these samples is the ash, phosphoric acid, or protein so high as the +minimum found in the all-malt beers. The same will be seen in the case +of the malt-and-corn beers. In none of the malt-and-corn beers is the +ash, protein, or phosphoric acid so high as the minimum found in the +all-malt beers, and the same is true of the mixtures of malt and +cerealin and of malt, brewer's sugar, and cerealin. This shows clearly +that the commercial beers made in this country from malt and malt +substitutes can be distinguished readily from all-malt beers. + +When the average composition of the 21 all-malt beers examined is taken +into consideration it will be seen that there is a very sharp line of +demarcation between the all-malt and the malt, rice, and corn products. +From the figures which were obtained upon American beers it would seem +that protein as a rule is more sharply reduced by the addition of malt +substitutes than is the ash or the phosphoric acid, although where corn +or cerealin is used there is a very marked reduction in the amount of +phosphoric acid. It would appear, therefore, from the results of this +investigation that in the consideration of American beers it will be +comparatively easy to draw a line between beers made solely from malt +and those made from mixtures of malt with rice, corn, and other +substitutes. + +This conclusion is not entirely in agreement with the results which have +been obtained by others upon foreign beers, in the preparation of which +low protein barleys have been used. Joseph Race[1] has reported some +interesting results of an investigation carried on for the same purpose +as that for which this particular investigation was undertaken; that is, +to distinguish between all-malt beers and those made from substitutes. +His results do not show as sharp a reduction of the protein, but he +found in his all-malt beers a very much lower percentage of total +protein than was found in the malt beers of this country. He did +observe, however, a material reduction of the phosphoric acid due to the +use of substitutes. Unfortunately, he made his determination of +phosphoric acid in the ash, and while he reports a marked difference +between the phosphoric acid content of the malt beers and those made +from substitutes, his total figures for phosphoric acid are much lower +than those reported in this bulletin. For this reason the figures for +total phosphoric acid given by him are not at all comparable with those +determined by the moist combustion method, by the uranium acetate +method, or by the method of ashing with calcium acetate.[2] + +[Footnote 1: J. Soc. Chem. Ind., 27 (1908), 544-547.] + +[Footnote 2: Riley, in his report to the Association of Official +Agricultural Chemists for the year 1913, showed that a large proportion +of the phosphoric acid was ordinarily lost when the beer was directly +ashed (J. Assoc. Off. Agr. Chemists, 1 (1915), 138-143). For this +reason, in comparing the amount of phosphoric acid given in the +literature on beers, it is very essential to know the method used for +determining the phosphoric acid.] + + +The same fact observed by Race, namely, that foreign beers are of low +protein content, is shown very clearly in the published literature on +European beers in general. Koenig[3] gives the following results of +analyses made by himself and H. Weigmann of two all-malt beers, +calculated to the basis of a wort containing 15 per cont of solids: + ++-----------------------------+-----------+-----------+-----------+ +|Beer and percentage of wort. | Protein. | Ash. |Phosphoric | +| | | | acid. | ++-----------------------------+-----------+-----------+-----------+ +| | Per cent. | Per cent. | Per cent. | +|Pure malt beer: | | | | +| 12 percent wort | 0.548 | 0.259 | 0.098 | +| 14 percent wort | .457 | .214 | .076 | ++-----------------------------+-----------+-----------+-----------+ + + +From these results of Koenig it will be seen that the protein content of +these beers is considerably less than that of the beers examined by the +writers. As the phosphoric acid and ash results, however, are +practically the same as in American beers, it might be expected that the +use of substitutes in place of the low-protein malt would not show so +sharp a reduction of the protein as was found by the authors, although +one would expect a reduction in phosphoric acid and ash similar to that +found in American beers. This is confirmed by the results obtained by +Race. + +Robert Wahl[4] made parallel brewings of a high-protein barley and a +low-protein barley, and from these obtained two beers which, when +calculated to a uniform wort with 15 per cent of solids, showed a total +protein in the beer made from the low-protein malt of 0.734 per cent, +and in the beer made from the high-protein malt 1.041 per cent. This +clearly indicates that where a beer is made from high-protein barley, as +is the case with practically all of the beers made in this country,[5] +the reduction in protein by the use of substitutes will be a valuable +index to the true nature of the product. This, when taken in connection +with the reduction of phosphoric acid brought about by the use of +substitutes, gives two factors of value in judging American beers, to +determine whether or not substitutes have been used; while in the case +of beers made from low-protein barley there is practically only one +factor, namely, the reduction of phosphoric acid. + +[Footnote 3: Koenig, F. J., Chemie der Menschlichen Nahrungs- und Genussmittel, +4th ed., v. 1, p. 1154. Berlin, 1903.] + +[Footnote 4: Am. Brewers' Rev., 18 (1904), 339.] + +[Footnote 5: Wahl, Robert. _In_ Am. Brewers' Rev., 29 (1915), 316-317.] + + +After this rather extensive study had been made at the three breweries, +the investigation was extended to include breweries in various sections +of the country where different types of raw materials were used. A +special effort was made to obtain authentic samples of practically all +of the malt beers made in this country and also a large series of +malt-and-rice and malt-and-corn beers.

All of these results show +practically the same condition noted in the other samples of malt beer; +that is, a comparatively high protein and phosphoric acid content as +compared with beers made in part from rice or corn. These malt beers +show figures considerably higher in protein than those given in the +literature for all-malt beers made from the low-protein malt of Europe. + + +TABLE IX.--_Analyses of all-malt American beers._ + +Column Headings: + +A: Sample No. +B: Alcohol. +C: Extract (Schultz and Ostermann). +D: Extract in original wort (calculated). +E: Degree of fermentation. +F: Total acid as lactic. +G: Volatile acid as acetic. +H: Reducing sugars as anhydrous maltose. +I: Dextrin. +J: Protein (N x 6.25). +K: Ash. +L: Phosphoric acid (as P_{2}O_{5}). +M: Undetermined. +N: Polarimeter. +O: Color (Lovibond) in 1/4-inch cell. +P: Calculated to basis of wort with 15 per cent of solids. +Q: Protein (N x 6.25). +R: Ash. +S: Phosphoric acid (as P_{2}O_{5}). + ++-------+------+-----+-----+-----+-----+-----+-----+-----+-----+ +| | | | | | | | | | | +| | | | | | | | | | | +| A | B | C | D | E | F | G | H | I | J | ++-------+------+-----+-----+-----+-----+-----+-----+-----+-----+ +| | Per | | | | | | | | | +| | cent.| | | | | | | | | +| | by | Per | Per | | Per | Per | Per | Per | Per | +| |weight|cent.|cent.| |cent.|cent.|cent.|cent.|cent.| +|22017-D| 3.83 | 5.06|12.72|60.22|0.214|0.001| 1.32| 2.30|0.603| +|22018-D| 3.90 | 5.06|12.86|60.65| .223| .002| 1.34| 2.03| .606| +|22020-D| 3.69 | 5.12|12.50|59.04| .234| .002| 1.57| 2.20| .630| +|22021-D| 3.63 | 5.54|12.80|56.72| .219| .001| 1.82| 2.15| .626| +|16289-C| 3.00 | 5.88|11.88|50.50| .228| .003| 1.33| 2.68| .752| +|16299-C| 2.84 | 6.02|11.70|48.55| .232| .012| 1.38| 2.77| .724| +|20714-D| 3.07 | 5.80|11.94|51.42| .241| .012| 1.45| 2.64| .721| +|20715-D| 2.95 | 5.77|11.67|50.56| .228| .009| 1.43| 2.67| .725| +|23571-E| 3.68 | 4.44|11.80|62.45| .232| .010| 1.06| 1.67| .653| +|23585-E| 3.60 | 5.04|12.24|58.82| .277| .005| 1.36| 1.81| .811| +|23528-E| 3.28 | 6.36|12.92|50.80| .384| .016| 1.62| 2.74| .905| +|23533-E| 3.41 | 5.48|12.30|55.45| .232| .008| 1.48| 2.44| .612| +|23537-E| 3.80 | 7.26|14.86|51.35| .250| .012| 2.51| 2.95| .802| +|23588-E| 3.16 | 6.11|12.43|50.84| .250| .008| 1.93| 2.41| .797| +|23538-E| 3.13 | 6.61|12.77|48.24| .250| .009| 2.13| 2.82| .612| +|23589-E| 3.35 | 6.21|12.91|51.90| .178| .017| 1.78| 2.87| .627| +|23539-E| 3.22 | 6.63|13.27|48.53| .312| .017| 2.18| 2.58| .778| +|23540-E| 3.93 | 6.77|14.63|53.73| .348| .007| 2.64| 1.87|1.010| +|23590-E| 3.48 | 5.45|12.41|56.09| .375| .010| 2.21| 1.48| .892| +|23541-E| 3.12 | 5.06|11.30|55.22| .259| .004| 1.69| 1.27| .777| +|14004-H| 3.07 | 5.55|11.69|52.54| .223| .013| 1.59| 2.64| .615| ++-------+------+-----+-----+-----+-----+-----+-----+-----+-----+ + ++-------+-----+-----+-----+-------+-------+-----------------+ +| | | | | | | P | +| | | | | | |-----+-----+-----+ +| A | K | L | M | N | O | Q | R | S | ++-------+-----+-----+-----+-------+-------+-----+-----+-----+ +| | | | | | | | | | +| | | | | | | | | | +| | Per | Per | Per |Degrees|Degrees| Per | Per | Per | +| |cent.|cent.|cent.| V. | [1] |cent.|cent.|cent.| +|22017-D|0.206|0.079| 0.63| ... | 12 |0.712|0.243|0.093| +|22018-D| .199| .077| .88| ... | 13 | .701| .230| .090| +|22020-D| .203| .080| .52| ... | 11 | .756| .244| .096| +|22021-D| .205| .081| .74| ... | 10 | .734| .240| .095| +|16289-C| .242| .081| .88| +36.8 | ... | .950| .306| .102| +|16299-C| .237| .088| .91| +40.0 | ... | .932| .304| .113| +|20714-D| .225| .089| .76| +36.4 | 3 | .906| .283| .112| +|20715-D| .213| .088| .73| +36.0 | 4 | .932| .274| .113| +|23571-E| .229| .096| .83| +21.6 | ... | .830| .291| .122| +|23585-E| .257| .102| .80| +23.2 | 6 | .994| .315| .124| +|23528-E| .239| .123| .86| +37.2 | 13 |1.051| .277| .143| +|23533-E| .200| .086| .75| +33.6 | 3 | .747| .244| .105| +|23537-E| .228| .098| .77| +44.0 | 14 | .809| .230| .099| +|23588-E| .208| .086| .76| +37.2 | 4 | .952| .251| .104| +|23538-E| .225| .087| .82| +43.6 | 9 | .719| .264| .102| +|23589-E| .204| .075| .73| +40.0 | 7 | .729| .237| .087| +|23539-E| .248| .097| .84| +38.8 | 22 | .879| .280| .109| +|23540-E| .324| .129| .93| +34.0 | 18 |1.035| .332| .132| +|23590-E| .264| .109| .60| +25.6 | 7 |1.079| .319| .132| +|23541-E| .253| .087| 1.07| +20.0 | 4 |1.031| .336| .115| +|14004-H| .207| .072| .49| ... | 5 | .789| .266| .092| ++-------+-----+-----+-----+-------+-------+-----+-----+-----+ + +[Footnote 1: Brewer's scale.] + + +In Tables X and XI are given the results for beers made from malt and +rice and from malt and corn.

Brewer's scale.] + + +The data reported in Tables X, XI, and XII give the results of analyses +of commercial American beers obtained from various breweries in +different parts of the United States as these beers are found on the +market at the present time; hence, they are of general value for the +purpose of showing the composition of American beers. These data also +are of considerable interest when we compare them with data relating to +American beers published by the department in 1887.[1] A comparison of +these two sets of figures shows that beers made at the present time have +a much lower percentage of alcohol and are made from a wort containing a +much lower percentage of solids than beers made a generation ago. The +average of 28 samples examined and reported in 1887 in the publication +cited[1] showed an average alcohol content of 4.63 per cent by weight +and solids in the original wort of 14.79 per cent, while the average of +72 beers representing the products now on the market showed an average +of 3.52 per cent by weight of alcohol and solids in the original wort of +12.50 per cent. This is a reduction of 1.11 per cent by weight of +alcohol and 2.23 per cent of solids in the original wort. + +[Footnote 1: U. S. Dept. Agr., Div. Chem., Bul. 13, 1887, pt. 3, p. 282.] + + +CONCLUSIONS. + +The all-malt beers made in this country contain higher percentages of +protein than the all-malt beers made in Europe, owing to the use in this +country of a barley high in protein. + +The use of rice, corn or corn products, and brewer's sugar as +substitutes for malt reduces the content of protein, ash, and phosphoric +acid in the finished beer. + +This difference, as regards the protein, ash, and phosphoric acid, is a +sufficient basis for distinguishing the all-malt beers made in this +country from those containing the commercial mixtures of rice, corn, +cerealin, and brewer's sugar. + +It is necessary to calculate analytical results to the basis of a common +wort in order to interpret them properly. + + * * * * * + + ADDITIONAL COPIES + OF THIS PUBLICATION MAY BE PROCURED FROM + THE SUPERINTENDENT OF DOCUMENTS + GOVERNMENT PRINTING OFFICE + WASHINGTON, D.

Information about Donations to the Project Gutenberg +Literary Archive Foundation + +Project Gutenberg-tm depends upon and cannot survive without wide +spread public support and donations to carry out its mission of +increasing the number of public domain and licensed works that can be +freely distributed in machine readable form accessible by the widest +array of equipment including outdated equipment. Many small donations +($1 to $5,000) are particularly important to maintaining tax exempt +status with the IRS. + +The Foundation is committed to complying with the laws regulating +charities and charitable donations in all 50 states of the United +States. Compliance requirements are not uniform and it takes a +considerable effort, much paperwork and many fees to meet and keep up +with these requirements. We do not solicit donations in locations +where we have not received written confirmation of compliance. To +SEND DONATIONS or determine the status of compliance for any +particular state visit http://pglaf.org + +While we cannot and do not solicit contributions from states where we +have not met the solicitation requirements, we know of no prohibition +against accepting unsolicited donations from donors in such states who +approach us with offers to donate. + +International donations are gratefully accepted, but we cannot make +any statements concerning tax treatment of donations received from +outside the United States. U.S. laws alone swamp our small staff. + +Please check the Project Gutenberg Web pages for current donation +methods and addresses.
