Trader Joe's gets praise for their cheap wine, but they also have a good selection of interesting beers. I especially love how TJ's lets you make your own 6 pack. Last time I was there, I got a variety of wheat beers so my friends and I could do a taste-test of sorts. The unanimous favorite was the Pyramid Apricot Wiezen, which was unique in that it had a fruity "beforetaste" (if that's a word) rather than a fruity aftertaste.
Have you made any interesting beer discoveries there?
