Ettal Abbey was founded on 28 April 1330 by Emperor Louis IV, known as the Bavarian. In the 15th and 16th centuries, the monastery had a brewery in the famous village of Oberammergau in Upper Bavaria. The monastery brewery at Ettal Abbey was established in 1609. Alongside agriculture, the monastery brewery is the oldest enterprise run by the Benedictine abbey at Ettal. It has been brewing beer on a continuous basis for over 400 years. Even today, Benediktiner Weissbier for the German and Austrian market is still brewed exclusively at Ettal.
