[Footnote 1: Brewer's scale.]

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.

[Footnote 1: 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.
