Ethyl alcohol is a proven human carcinogen.  This is the only problem
with wine.  Early man would be exposed to it only on a seasonnal basis as
illustrated by the grackels (a type of blackbird)here in Texas in the
fall when the imbide of certain fermented berries and become falling-down
drunk (quite a sight).

Regular wine consumption does lead to high incidence of liver cancer in
Europeans and a doubling of risk of breast cancer in women.  The
beneficial effects of wine such as the anti-oxidant flavanoids can be
obtained from grape juice, without the risk.

I feel however that intoxicants do serve an important part in human life
(hey, life's a bitch).  No matter what form you chose, exercise
moderation.  If you know of a form of intoxicant that is without risk,
please send me some!
