MALT LIQUORS.

Malt liquors, properly so called, should be made only of malted barley, hops, yeast and water, but other materials are also used. Porter is a beer of a high percentage of alcohol and made from malt dried at a high temperature, which gives it its dark color. Ale is pale beer with considerable alcohol and made of pale malt, with more hop extract than porter.

As every per cent. of sugar in the malt yields by fermentation about half a per cent. of alcohol, it is evident that ale, porter, and lager beer are stronger or weaker, as more or less malt is used in making them.
