No domestics for me.
Having lived in Italy for a time, I got used to Peroni and Moretti. A bit darker than the watered-down pee they serve at parties here. Sometimes you can find some classy folks who will serve Magic Hat and Blue Moon, but I end up usually bringing my own bottles. I like Chimay and Red Stripe a lot. I was much less discriminating my freshman year--I actually drank Schlitz and Genny Lite. Yikes.
Mr. Munchkin03 likes Guinness a lot, but I can't handle it. He also mixes his own black and tans.
But, I really don't do beer that much...I don't go to fraternity parties anymore, and the bars and parties that I DO attend usually have more options as to drinks. No one's buying the $8.99 24-pack much anymore.
