Favorites:
Rogue Dead Guy Ale -- a good "all-rounder", not heavy, not particularly hoppy, not adulterated with flavor, just something that I can almost always reach for when I want a beer.
Rogue Shakespeare Stout/Mocha Porter -- it's been so long since I've had either of these, and they're so close, that I honestly don't remember the difference. These are much heavier, so I tend to go for them during the coldest months. They hit me as having some maltiness and some dark chocolate & coffee undertones, with a fairly clean finish (considering what you were just drinking, it doesn't coat your mouth).
Budweiser -- tastes like someone figured out how to ferment water. retch
Anchor Christmas Blend -- just about the only flavored beer I like, just a perfect combination of spices to give it a "seasonal" flavor, without tasting fruity or whatnot (I think it's primarily nutmeg, cloves, cinnamon and the like, perhaps some oats? not sure...). Again, a little on the heavier side, so not something I'd reach for every day, but really good. And don't ask me which year -- I know they change their recipe each year, but they're close enough together -- and my palette sufficiently insensitive -- that I don't really taste the difference.
