It produces beer types such as Dunkel, Helles, and Pilsner, plus seasonal Bock and Pale lagers.

[3] The origins of the Aldersbach brewery, in the Klosterwinkel region close to Passau, go back to the High Middle Ages.

[1] As early as 1268, the brewery was documented in an arbitration letter from Count Albert von Hals.

[5] Climate changes and phylloxera disasters put an end to viticulture and beer became the main and popular drink in Bavaria.

Secularization hit Aldersbach hard: in 1803 the monastery was dissolved and the brewery was initially sold to a beer brewer from Passau.

A few years later, in 1811, Johann Adam von Aretin acquired the monastery brewery; as early as 1806 he had bought forest and arable land around Heidelberg Palace.
