Castillero Diablo cabernet can be had for under $8. Chille heavily subsidizes their wine industry so you can get quite a bang for the buck when you buy Chillean wine.
I think this is the answer for everything. Don't smoke, don't drink especially if your on AAS. I don't do either, but if I want to have a few beers every few weekends I don't think thats gonna hurt me even if I'm on steroids. Look at all the pros that mix it up a lot more than most of us on this board, and their still kicking (for how long I don't know).
A glass of wine or even a few glasses won't kill you, as long as your not making it a daily habit.
