Brauerei Weihenstephan, located at the monastery site since at least 1040, is said to be the world's oldest continuously operating brewery.
A dormitory for monks that originally adjoined the building disappears from records by the end of the eighth century.
The Weihenstephan Brewery can trace its roots at the abbey to 768, as a document from that year refers to a hop garden in the area paying a tithe to the monastery.
Since 1923, the brewery has been known as the Bavarian State Brewery Weihenstephan (in German Bayerische Staatsbrauerei Weihenstephan), and is operated in conjunction with the Technical University of Munich as both a state-of-the-art production facility and a centre for learning.
[2] The brewery produces a range of pale lagers and wheat beers including Weihenstephaner Weissbier, a 5.4% ABV weissbier which is available in filtered (Kristall)[3] and unfiltered (Hefe)[4] versions.
