The first references to a brewery in the Weltenburg Monastery are to be found in the Weltenburg Nekrologium, in which it states that the master brewer died. Another scientifically recognized source is a recorded entry in the “Libellus Traditionum”, which is over 900 years old, and which dates from shortly before or after 1050.

In the barely millennium to the present day, monastic beer production in Weltenburg was only interrupted by the secularization from 1803 to 1846. In 1846 the brewery became monastery property again, and it has remained there to this day. The Weltenburg monastery brewery can therefore rightly be called the oldest monastery brewery in the world.
