I don't want to get too boosterish, but Oregon is starting to lay in a few layers of bedrock itself. I was reminded of another in an email from Oregon State pointing me to a webpage they recently finished to promote the Fermentation Sciences program. It used to be that if you wanted to get a undergrad degree in brewing, it meant heading to Davis. Now you have OSU as an alternative, and it's nothing to sniff at. The university has wisely put Tom Shellhammer out in front--as one of the world leaders in hop research, he's a pretty attractive draw. You have hop fields nearby, the campus has its own little brewery, and of course, you can't swing a dead cat without hitting another brewer in the nose.
No place in Oregon is about to eclipse Munich anytime soon. But if you wanted to Munich-ize your region, you'd do what we're doing here. Over time, you'd see large breweries emerge, see agriculture respond to the brewing industry (including, as in Hood River, the farming of wild yeasts), see schools dedicated to teaching brewing, research done to support it, and a very broad base of local culture consuming it.
So far, so good.
