Until the end of the 19th century, twelve generations of the Schuster family managed the "Sixthof" for the Bernried monastery. After secularisation in 1803, the farm became their property. In 1873, Anton Schuster founded the first brewery in Aying. A small brewhouse with a vaulted cellar and its own beer tap was built on the east side of the Sixthof: Today's "Bräustüberl".
When Anton Schuster died in 1890, his 20-year-old son Kaspar had to take over the "Sixthof" and the brewery. It was probably the debts from the construction of the brewery that led to the ruin of the farm and the sale of the individual buildings. The farm initially went to a brewery owner in nearby Siegertsbrunn. On October 30, 1897, it was finally acquired by the great-great-grandfather of the current generation, Johann Liebhard.
