The story
In 1910, master butcher Karl and his wife Johanna Händlmaier founded a butcher shop on Gesandtenstraße in Regensburg. In 1914, Johanna Händlmaier created a recipe for a sweet Bavarian mustard, which today is principally consumed with Weißwurst and Leberkäse.
In 1945, after the end of the Second World War, Karl Händlmaier's son Joseph took over the butcher shop and ran it together with his wife. After the death of Joseph in 1955, his widow Luise ran the butcher shop until 1964, when, at the age of 54, she sold all six locations to a local sausage producer to concentrate exclusively on the production and sale of the sweet mustard.
After the death of Luise Händlmaier in 1981, the company was run by Christa Aumer, Luise's daughter. In 1988, Christa Aumer's son Franz Wunderlich assumed control of the company.
The firm relocated in 1992 from the Regensburg city center into an industrial area Haslbach further outside the city. From there, the company also produces mustard for private label discount chains such as Aldi or Lidl.
