As part of NPR's summer travel series, Rob Schmitz takes us to a remote corner of southern Germany, where a nun has been brewing Bavarian beer for nearly five decades.
For centuries, German law has stipulated that beer can only be made from four ingredients. But as Germany embraces craft beer, some believe the law impedes good brewing.
A German brewers association is seeking UNESCO World Heritage status for a 500-year-old law that dictates how to make beer. The brewers argue that the law ensures purity in German beers. But others say the law is from a bygone era.
