The fact that monks breed beer in Weltenburg is documented for the first time in 1050, which is why Weltenburg promotes the "oldest monastery brewery in the world". The annual output is almost 30,000 hectoliters. A beer garden was set up in the cloister yard, where brewery products were served. Since April 2007, the brewery has been offering guided tours on the weekends. The "World Monastery Baroque Dark" was awarded the "World Beer Cup" in 2004, 2008 and 2012 as the best dark beer in the world.
