These guys get it - they've got plenty of interesting stuff for beer nerds, at totally reasonable prices. Granted, I had a large backlog of reviews to write after going to Denver for GABF, so the specific beers are probably totally irrelevant by now (seems like the sort of place where beer rotates frequently), but when I was there, I got a flight of 4: a cucumber gose (fantastic), a bba sour with zin grape must (also excellent), a passion fruit gose (good, but not as fruity as I was hoping - but still good), and a bba cherry stout (pretty good - not my favorite bba stout, but I've got high standards. Was still pretty good though.) They do serve individual 3oz pours for between $2-4, but you get a discount if you do a flight of 4 - $10 for a core flight, or $11 for a flight of the 4 priciest ones. Alternatively, if, as was the case when I was there a few weeks ago, there are exactly four beers you want tasters of, then at least as of right now, you should check in on yelp, claim your free taster (it can be any beer, so have them comp one of the $4 tasters), then get the other three individually and it'll be less than $11!
I also got a free bonus totally by accident: I got there on Wednesday around 8, had no idea they have no-cover live jazz from 7-9 on Wednesday. Was pretty good, too! Probably partially explains why it was so busy on a Wednesday night, too - though also partially probably because it was GABF week, the same reason I was there. Not sure how busy it is on a normal day, but regardless, despite being pretty busy, I was still able to get beer almost immediately.
This would definitely be one of the breweries I'd make sure to pop back into if I was ever back in Denver. (And if possible, I'd go on a Wednesday evening!)
