Favorite beer? Well, like you hear so often with food, I think the approach is to consume locally and in season. "In season" meaning IPA's in the spring and fall (and summer if not too hot), Weissbeers and pilsners in summer, Mai Bocks (or Oktoberfests, basically the same) in late spring and fall, Stouts in fall and winter, and Bocks and barleywines in winter. If you're not sure of what's "in season", consult your local brewpub. If it's of any quality whatsover you should be able to tell what's in season by what they have on tap. Of course, there can be exceptions to the rule - like it's nice to have a good chocolate stout or barleywine with dessert year-round, or if I happen to be eating Southwestern food in the winter I'll still get an IPA with it, etc. That said, in a pinch I'll get a Sierra Nevada Pale Ale when I'm in a restaurant in my hometown since that's pretty widely available in NYC. If not, Yuengling or Rolling Rock is just fine.
