• Wine is an alcoholic beverage made from fermented
grapes or other fruits. The natural chemical balance of
grapes lets them ferment without the addition of
sugars, acids, enzymes, water, or other nutrients. Yeast
consumes the sugars in the grapes and converts them
into alcohol. Different varieties of grapes and strains of
yeasts produce different types of wine. The well-known
variations result from the very complex interactions
between the biochemical development of the fruit,
reactions involved in fermentation, and human
intervention in the overall process. The final product
may contain tens of thousands of chemical compounds
in amounts varying from a few percent to a few parts
per billion.
How is wine made?
• Yeast is the magical ingredient that turns
grape juice into wine. Interestingly enough,
there is actually wild yeast spores in the air
and all that is really needed to make wine is
an open container of grape juice and time.
The result however, would probably not be
the most palatable of beverages.
Wine color?
• You probably know that there are green grapes
and black grapes and different grapes are used
to make different wines.
But how too make the wine become different
color on it?
The way a wine gets its color is by letting the
skins soak in the juice during fermentation. You
can actually make white wine from black
grapes by not letting the skins stay in contact
with the juice. Champagne is one of the most
famous examples.
What gives each wine the flavor?
• Even though there are very few ingredients, there
are many things which influence the taste of wine.
First of all, there are many varieties of grapes.
Each grape variety will produce different flavors,
aromas, and even textures.
• In addition, the soil and climate where the grapes
are grown drastically affect these variables.
• Not only that, but the wine maker can control
various things by the technique, temperature and
yeast used during fermentation. Other variables
such as fermenting or storing in oak barrels will
also affect the taste.

Storage
• Storage is an important consideration for wine
that is being kept for long-term aging. While
most wine is consumed within 24 hours of
purchase, fine wines are often set aside for
long-term storage. Wine is one of the few
commodities that can improve with age but it
can also rapidly deteriorate if kept in
inadequate conditions. The three factors that
have the most direct impact on a wine's
condition are light, humidity and temperature.
