Get me a Fat Tire and I'm a happy man, its been my favorite for quite awhile. I also enjoy trying new IPA's as I have recently become a fan. Finally, Guinness Foreign Extra is superb...something you have to try if you haven't tried the legit Guinness.
The one in my hand, of course. In general, though, I like hoppy beers more than malty, sweet beers. I often drink the Costco brand snack pack, with two pale ales, a brown ale, and a wheat for 5-10 bucks less per case than Harpoon, Sam Adams or Sierra Nevada.
Abita Amber (local bias)
Widmer Hefeweizen (or pretty much any hefeweizen). There's a local distributor, but I haven't seen it on sale anywhere. Need to call up the old guy down the street who runs a grocery store and have him get some for me.
Had Shiner Bock for the first time a few weeks ago and liked it a lot. Need to drink that again next time I get a chance.
