I drink darker beers. I grew up in Croatia / Germany and I've learned to appreciate them.
I love everything from a good Hef (Widmer, Franziskaner) to a stout such as Guinness or Murphy's. I love Smithwicks and the other beer that Guinness makes - Kilkenny! I wish they had that in the states.
I worked as a volunteer at the Great American Beer Fest in Denver for the last three years. I got a chance to sample some awesome beers every time and it inspired me to brew my own as well. I'm a fan of Rogue, Dogfish Head, Flying Dog, Fat Tire, 98 Shilling, Pete's Wicked... too many to name. Being from CO, I'm a big fan of microbrews. That state has a million of them and I've never been dissapointed by any.
As far as mainstream beers, I do get an occasional Bud Light or a Coors but I do not really like them too much cause they are like Gatorade. When I'm buying my own beer, it's usually Guinness or Sam Adams. I believe Sam Adams to be best mass produced American beer. When I was in Germany last April, I only drank beers I haven't had before!
I can't really do Miller, PBR, Michelob, Nat Ice and such... to tasteless. Heineken is as mellow as I like to go...
Cheers to all ya!
