My personal beer of choice is pretty much any kind of IPA (India Pale Ale, for those who don't know). I actually didn't know what to do last night when my usual bar didn't have Rampant IPA on tap any more. I generally go for high-alcohol beers; most of them just taste good to me. Anchor Steam is pretty good, I was introduced to that one by my boss. Smithwick's is good, Fat Tire is good, most things by Hofbrauer are good... Yeah I really like beer, I could keep naming kinds I like but that seems unnecessary.
I can't drink straight liquor like I did when I was a freshman or a sophomore in college. I kinda pounded my body's acceptance of those into the ground by drinking too much. I still drink too much, but now I do it with mixed drinks. I'm a big fan of rum and Coke, especially if I want to get really fucked up: mix two shots of Kraken spiced rum with a can of coke, repeat as needed. If I drink vodka it's in a screwdriver. Jameson and ginger ale is really good. Long Island iced teas can be good, but only if you've got a really good bartender, otherwise they can taste like death in a glass.
