I'm in the Everett, WA area for a couple of days. I visited 3 breweries so far. Scuttlebutt was quite good, and McMenamins is a 'don't bother.' The most interesting is a little nano brewery named Justice Brewing. It was there that I tried a sour beer fermented with blue cheese cultures. The nose was totally blue cheese, but the flavor only carried hints of it. It was surprisingly good. about half of his beers were sour. All were decent. Some quite good. Worth a try if you have opportunity.
He brews in the garage behind his house and was very welcoming. A nice guy with a very interesting take on beer.
