On a hilltop in Bavaria just south of Munich lies the Andechs Abbey, famous for the monk-made beer, beautiful hiking, organic dairy and produce and an all-around monastery/brewery German experience. Nearby are the lakefront towns of Dießen and Herrsching, known to German locals as relaxing places to kick back.
A visit to Avery Brewing Company has its address in Boulder, Colorado. But really it's in the Gunbarrel area of Boulder County. Each local brewery here has its own gig, and Avery's is lots of diverse beer types, plus a surprisingly creative and delicious kitchen! Check out the photos of their wonderful, two-story taproom.
A visit to a very congenial brewery and taproom, New Belgium Brewery in Ft. Collins, Colorado. You might know its Fat Tire beer. In my experience, New Belgium's digs could qualify as a beer garten in many ways, including the way people are invited to hang out there, take the free tour, and feel comfortable doing so.
