_BEER AND ALES._--These are made from grains and hops, which contain no
sugar, it is true, but are composed of starch, which may be changed into
sugar. When a seed of grain is put into the ground and begins to grow, the
starch in it becomes sugar, which feeds the young plant. When a brewer
wishes to make beer, he takes some grain, puts it in a dark place, wets it,
and leaves it to sprout, or begin to grow. Then he puts it into an oven to
dry it, and make it stop growing. This makes what is called _malt_. The
malt is mashed and soaked in warm water to get the sugar out of it; this
forms a liquid called _sweet wort_. The wort is separated from the mashed
grain and boiled; yeast is mixed with it to help it to ferment more
quickly; it soon becomes changed; a dirty yellow scum filled with bubbles
comes to the top, which we know is the poisonous carbonic acid gas; the
other poison, alcohol, stays in the liquid and makes the beer taste good to
those who like it.
Liquors made from grain are called _malt liquors_. Lager beer, and all
kinds of ales and porters, are malt liquors. They make people dull,
sluggish, and stupid who drink much of them. They do much mischief in the
body, though it takes a larger quantity of any one of them to make a person
drunk than it does of whiskey or brandy.

DISTILLATION.
How does the sugar in grapes and other fruits become alcohol?--"By
fermenting." Yes, and liquors made by fermenting are called _fermented
liquors_. What other alcoholic drinks have you heard about beside cider,
wines, beer, and ales?--"Gin, whiskey, brandy, rum." These are stronger
than the fermented liquors, that is, they contain more alcohol; they are
made by what is called _distillation_.
If you boil water, and let the steam from it fall upon a cold plate, the
steam will change back into liquid and become _distilled_ water. Making a
liquid boil, catching the vapor or steam and cooling it, is what we mean by
distillation.
