Nice to see not all of my fellow Reds are Stella drinking heathens.
Just got back from the US like a month ago - hit up all the good ones Anchor, 21st Ammendment, Stone, Alesmith, Green Flash, Pizza Port, Lost Abbey/Port Brewing, and Uncommon in Cali. Visited some epic craft beer bars there too, Zeitgeist in particular was eye opening. Would have loved to hit Alpine but maybe next time. Oh and of course Russian River and was there on the second to last day of the PtY thing at the brewery.
edit: oh and I forgot Lagunitas too. For a 'small brewery' their facility is humongous.
In Portland I checked out this up and coming brewery called The Commons (look out for them, they do some really cool Belgian/German style beers which the craft industry has been neglecting a bit), Hopworks Urban Brewery and checked out both the Rogue Bar (whose food was ridiculously good) and the Deschutes Bar. The most epic craft beer bar there was Apex - 50 taps of some awesome shit. By far the highlight though was sitting down and having a chat with craft beer legend Alan Sprints (Hair of the Dog) who made some time to talk to us. Drinking Adam from the Wood 2011 was a close second.
Best beer I had in the US was suprisingly not the Younger, but a beer called Allocation IIPA - a collab between Portland's Barley Browns and Boneyard.
Planning another trip soon, there were a couple we wanted to hit but couldn't make and we'd like to give Denver a go and check out the likes of Great Divide and some others down that way.
