In Table XII have been brought together the results of the examination of a large number of commercial beers of American production, which were represented to be made from malt and hops. This representation subsequently proved to be false, although exact information as to the amount or kind of substitute used is not available. 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. TABLE XII.--_Analyses of American beers incorrectly represented to be all-malt._ 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.| | 2417-E| 3.67 | 4.66|12.00|61.33|0.154|0.013| 1.59| 1.97|0.341| |36612-E| 3.10 | 7.55|13.75|45.09| .232| .017| 2.33| 3.93| .274| | 1146-E| 4.23 | 7.35|15.81|53.51| .241| .029| 2.21| 3.39| .472| | 3014-E| 3.26 | 6.74|13.26|49.17| .167| .014| 2.74| 2.56| .406| | 2538-E| 2.86 | 6.69|12.41|46.09| .214| .017| 3.22| 2.12| .390| | 1734-E| 3.55 | 6.55|13.65|52.02| .250| .028| 1.87| 3.58| .303| | 1154-E| 3.55 | 5.62|12.72|55.82| .187| .014| 1.88| 2.52| .352| | 1006-E| 3.58 | 4.74|11.90|60.17| .138| .017| 1.42| 1.99| .420| | 195-E| 3.56 | 4.21|11.33|62.84| .127| .008| 2.72| .77| .254| | 5022-E| 2.95 | 5.60|11.50|51.30| .133| .022| 2.30| 2.20| .233| | 1005-E| 2.69 | 5.33|10.71|50.24| .102| .010| 1.77| 2.34| .354| | 194-E| 3.18 | 4.00|10.36|61.39| .062| .017| 1.37| 1.58| .296| | 185-E| 3.44 | 3.92|10.80|63.70| .141| .011| 2.06| .97| .250| | 5314-E| 3.78 | 5.65|13.21|57.15| .151| .010| 1.46| 2.84| .416| | 4451-E| 3.23 | 6.52|12.98|49.77| .228| .009| 2.80| 2.44| .519| | 5696-E| 4.19 | 6.44|14.82|56.55| .268| .012| 2.15| 3.06| .309| | 3359-E| 4.96 | 7.43|17.35|57.18| .321| .019| 1.76| 3.74| .509|
