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 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.
It's almost time for Oktoberfest in Munich, Germany. However, if you have no Lederhosen or are in the Tampa area of Florida, you can celebrate the German tradition with a couple of quaffs from the International Beer Garten in Lutz, FL, just off the Suncoast Parkway at Highway 54 in Pasco County. Tell 'em I sent ya. Prost!
