American - New Glarus - Stone Soup (brewed and distributed in Wisconsin, USA)there are others I really like but New Glarus as a brewery is solid.
Worldwide - Westvleteren 12 (Trappist Ale brewed by monks for centuries, not "commies")
Trappist Ales are my
#1 beer world wide and only brewed in 5 monasteries world wide. Only 28 recipes exist.
I've tried at least 400-500 beers in the past 10 years. I usually get something new each time, and occasionally go back for favorites (of which there are dozens). I started saving bottles about 6 years ago. I plan on lining shelves in a game room with them. IMO - Beer is only as good as the variety available. One thing I've learned over the past decade is that you never know what you're missing until you've tried it - and good or bad, you still get drunk.
