Top 5: 1) Russian River Brewing - just an amazing brewery with incredible selection. From Pliny the Elder to Temptation, their beer really goes to all extremes. 2) Brouwerij Rodenbach N.V. - A limited selection available in America (Rodenbach, Rodenbach Grand Cru), but both are amazing beers that really changed my beer drinking world. For that, I give thanks. 3) Brasserie Dupont - Another beer revelation when I began drinking...gotta recognize those breweries that really changed your perception of beer. The Saison is still one of my favorite safety nets when I go out for a beer with friends. 4) Allagash Brewing - For a long time Allagash was a solid brewery with ok beers, but their recent additions (Interlude, Confluence, Odyssey, Fluxus, Curieux) have really vaulted them up in my mind's eye. Still holding out hope that I can wrangle some of their new barrel aged stuff (Gargamel, Vagabond) away from someone on the east coast...wink wink. 5) Jolly Pumpkin - A relatively new find for me, but man are there beers amazing. Oro de Calabaza, La Roja, Noel de Calabaza, etc...those crazy wild fermentation flavors are totally my thing. It's tough putting together a definitive top 5 though...ask me again in a few weeks and, while #1 wouldn't have changed, #'s 2-5 could be completely different. Founders, Victory, Deschutes, Boulevard, New Glarus, Three Floyds, Bell's...all great breweries that could easily slot somewhere in the top 5.
