German, Belgian, Czech, Polish beers.
I've been drinking Andechs and Augustiner, Tegernsee, those are all excellent Bavarian beers, and I had their Oktoberfest versions a few weeks ago at the event.
Haven't had Belgian beer in a while, since it's hard to get in Germany, but I have a weak spot for Kriek and Gueuze, also for Chimay Blue, which is probably the finest beer I've tasted.
Czech- can't go wrong with all of them, including Pilsner Urquell and Budweiser (the real Budweiser).
Polish- Okocim is fine fine fine, and strong strong strong. Had that a few weeks ago in Poland, and also had it in one of the many Polish joints in Detroit.
Out of the U.S. beers, I'm always game for Fat Tire, and many of the microbrews are great, Bridgeport and Deschutes comes to mind.
The Mexican beers are also great, I like Dos Equis and Negra Modelo, Dos Equis is actually German, or at least was started by a German immigrant. Not a Corona or Tecate fan.
