Alex -
If you've looked at this newsgroup for any length of time, you
should have seen plenty of references to these sites:

Lum Eisenman's online book / website on winemaking:
http://home.att.net/~lumeisenman/

Jack Keller's winemaking site:
http://winemaking.jackkeller.net

I won't recommend specific books - there are enough recent ones to fill
several bookshelves. If winemaking is a secret, it's probably the most
poorly-kept secret in human history.

I find it hard to believe that any family in Greece doesn't have at
least a couple of people in it who are convinced they already KNOW how
to make wine (although whether they would agree with each other about
anything, that's another question).

But if you're really looking for information, spend some time on those
sites. Searching Amazon.com for the keyword "winemaking" turned up a
list of several dozen books, including most of the ones most often
mentioned in posts on this newsgroup.
