condense and are collected as a separate
liquid.
The concentrated alcoholic liquid is then
modified in various ways for
consumption. It may be flavored with
herbs or spices, or aged in wood barrels.
The alcohol content is usually adjusted
with the addition of water before it’s
bottled for sale.The Distilling Process The essential principle
of distillation is a simple one: both alcohol
and aromatic substances are more volatile in
water than water itself, so they evaporate in
disproportionate amounts from wine and beer
and become concentrated in the vapor. But it’s
not a simple matter to make a delicious
distilled alcohol, or even a drinkable one.
Yeast fermentation produces thousands of
volatile substances, and not all of them are
desirable. Some are unpleasant, and others,
notably methanol, are dangerously toxic.
