Making Wine
The making of a basic table wine can be
divided into three stages. In the first, the ripe
grapes are crushed to free their juice. In the
second, the grape juice is fermented by sugar-
consuming, alcohol-producing yeasts into new
wine. The third stage is the aging or maturing
of the new wine. This is a period during which
the chemical constituents of the grape and the
products of fermentation react with each other
and with oxygen to form a relatively stable
ensemble of flavor molecules.
Crushing Grapes to Make the Must
Crushing extracts from the grape the liquid
that will become wine. This step therefore
determines to a large extent the final wine’s
composition and potential qualities.
