Herzoglich Bayerisches Brauhaus Tegernsee The company sees itself as the successor to a brewery allegedly founded around 1050 on Lake Tegernsee, where the Benedictine monastery Tegernsee was founded in 746. Today's brewery goes back to the year 1675, when Abbot Bernhard Wenzel brought the necessary brewing rights from Holzkirchen to Tegernsee.
In 1817, the Bavarian King Max I. Joseph acquired the secularized Benedictine monastery and brewery from Baron von Drechsel.
The brewery now operated under the name "Königlich Braunes Brauhaus Tegernsee". For dynastic reasons, the name later changed to "Ducal Bavarian Brewery". Since the purchase, the brewery has been owned by the Wittelsbach family and is now managed by Duchess Maria Anna in Bavaria, a daughter of Max Emanuel Herzog in Bavaria.
