Its hard for me to pinpoint all the breweries, I've gone to so many Onion Beer Societies, that I forgot how many different breweries I've tried, or which I liked the most. I usually just get a different 6 pack of whatever each week to have one when I get home from work. then I just drink PBR or Hamm's on the weekends. 1. Lakefront Brewery - for pretty much all the reasons Colby said...the new Local Acre is great, had it last night for the first time. It's the Brewery I know the most. I've been on that tour so many times, at one point Mr Klitsch joked and asked if me or any of my friends wanted to do the tour for him one afternoon. (best place for a wedding reception too!) 2. New Glarus - Spotted Cow is kinda an obvious pick, but still, great. 3. New Belgium - Went nuts and bought a 6 pack of the Fat Tire when I first saw it. Best 25 bucks I'd spent on beers ever (22oz bottles at that) 4. Capital Brewery - I love their winter ale, their Octoberfest was delicious as well 5. Furthermore - I've only tried the Fatty, but it ruled hard. Worst Brewery? MAGIC HAT. I got a 12 pack variety, and each beer made me wanna vomit more than the last, most notably the Winter 09 ale. Lemon water with carbonation. Worst beer ever (and yes, I've tried Steel Reserve)
