Go for red wines. There is immense variety, cheap, one glass should do, you can seem sophisticated, and it helps stave off alziemers.

Seriously, I stopped drinking for about 5 years and recently started having a glass of wine once or twice a week. It's much better than I ever would have expected, plus you can always say your doing it for the health benefits.

Also you can get some pretty good wines in the $5-10 range. I usually go to Trader Joe's or a similar type of store and they have a huge selection in that price range.

Also Sangria is a new favorite. It's mexican wine, red wine mixed with fruit juices. Very easy to drink and cheap also.
