The only real indulgence I allow myself to have as far as substances are concerned is the occasional glass of wine. I don't smoke, drink liquor or beer, and I don't touch drugs. Red wines are my favorite, maybe because they are so similarly colored to blood! I especially like dessert wines like port but I also enjoy Cabernet Sauvignon, Pinot Noir, and Syrah. Wine is very good to get your creative energies flowing. While your drinking it, it enhances the atmosphere. Therefore, wine can be a very enjoyable experience. I have created several stories while under the influence of wine, and they always turn out rather brilliant. The taste of wine is definitely something to be savored, if you don't enjoy the taste of wine, any wine, you shouldn't drink it.
What I like most about wine is the fact that you can drink it for other reasons than to just get inebriated, which is different than liquor or beer. I feel that every writer should try wine if they ever come across a severe writer's block, you'd be surprised at the results!
