The different ages of the beers sufficiently explain the slight variations in the results of the preceding analyses. The above general analyses are important. They show—
1st.—That the bitter beers of Messrs. Allsopp and Sons, and of Messrs. Bass and Co., contain only a moderate amount of alcohol; and
2nd.—That they contain an unusually large quantity of bitter extract, consisting of the extract of hops.
In estimating the quality and condition of beer, it is of great importance to ascertain its specific gravity, since this indicates to a considerable extent the amount of solid contents or extractive matter in the beer, which, as a rule, is in the newest and strongest beers.
It should be remembered, however, that alcohol, lighter than water, conceals in some measure the extract as estimated by the hydrometer, rendering the beer by so much the less dense as the proportion of alcohol is greatest.
It should also be borne in mind that the sugar, as the beer ages, gradually becomes converted into alcohol, and this again into acetic acid, and hence old beers usually possess a low specific gravity.
The effect of age in diminishing the density of beer is clearly shown in the following tables of specific gravities:—
