Beer: Hoegaarden if I have a choice; since most bars/restaurants around here don't have it, probably Blue Moon or Sam Adams when I am 21.
Wine: Depends entirely on what I'm eating. I developed a strong affinity toward good French wine when I was living abroad, though. If I am drinking wine without food, I'll generally try to find something more on the sweet side; if I'm serving it with food, dry.
Mixed drinks: Anything with white rum is usually good; vodka is my second choice. I'll drink (and savor) whisky if it's top-shelf stuff, but no cheap swill for me. As to what drinks I like? Bacardi-and-coke, White Russians, any sort of fruity blended ice drink, Long Island Iced teas, etc.
