I don't always drink beer, but when I do. . .
I'll pretty much drink anything that's ice cold and will always look for something that's on tap, even if I didn't really care for it when bottled. I've found that some IPAs are too bitter, but I do enjoy a number of IPAs. Lately, I've found myself with Belgian and Italian beers.
The past many years, I have been drinking Miller Lite when going out with friends. A large part of that is being good friends with a Miller distributor. Free beer is always good beer.

I have a number of close friends that like trying beers from smaller or less mainstream companies. One that I tried recently is the Lagunitas Hairy Eyeball. That was pretty good. Also some stuff like limited edition Goose Island and St. Bernardus. Some of them can be quite pricey though, like $10+ for about a liter sized bottle.
Anyways, what're your favorite beers?
