By this I mean where you have actually been onsite -- i.e. brewery tour, tasting room, official brewpub. Even local micro-breweries next door to you - a lot of them are great so why not? Just specify the location as I am a geography nut. Here are mine: 1) Sierra Nevada - Chico, California and Mills Creek, North Carolina I've been to both. I was just at the Mills Creek location last month and it literally blew me away. Great beers, great brewpub, and great outdoor concert vibe. 2) Cantillon - Brussels, Belgium This is one of the world's best Lambic style breweries. In the tasting room you can sample all of their amazing Lambic blends. This is how sour is supposed to taste. 3) Cigar City - Tampa, Florida This brewery is a must for anybody living there or passing through. All of the beers are worth sampling in the tasting room. 4) Stone - Escondido, California and Richmond, Virginia (also Berlin, Germany but I have not been to that one) The Escondido location has one of the most beautiful outdoor beer gardens; the one in Richmond is still a production brewery but they do have a decent tasting room. The beers are all hopped up but they do it right. 5) Mt. Pisgah Brewing - Black Mountain, North Carolina Fantastic music venue and brewery. Very informal and the brews are wonderfully complex. I'd go back again in an instant. Honorable mention: Brauhaus Georgbraeu - Berlin, Germany I had the best unfiltered German lager ever there! The beer garden is also not to be missed! Brooklyn Brewing - Brooklyn, New York Go there on a Saturday afternoon and see all of hipsters taking their babies to the brewery. Why didn't they have something like this when I was in my early 30's? Yuengling Brewery - Pottsville, Pennsylvania Yes, the beer is overloaded with corn and it definitely has that taste. The tour in the old, historical brewery is what makes it worthwhile.
