I'm a little biased because I love them so much, but I think a list of 50 beers to try should include all the Belgian trappist beers. Especially if their going to include 9 different varieties of stout.
Reaper, that's impressive that you've had 37 of those. I usually try to get different beers whenever I can and I don't think I could even buy 37 of those beers at the store. I don't even think I could hit that at the Great American Beer Festival. Well done!
