Hacker-Pschorr is a brewery in Munich, formed in 1972 out of the merger of two breweries, Hacker and Pschorr. Hacker was founded in 1417, 99 years before the enactment of the Reinheitsgebot Purity Law of 1516.

As one of six breweries located within Munich’s city limits, its beers are among those served at Oktoberfest.
In the late 18th century, Joseph Pschorr (1770-1841) bought the Hacker brewery from his father-in-law Peter-Paul Hacker. He subsequently founded a separate brewery under his own name. His two sons, Georg Pschorr (1798-1867) and Matthias Pschorr Sr., divided his estate by each taking control of one of the two separate breweries. In 1972, Hacker and Pschorr merged to form Hacker-Pschorr, but the beers were sold as separate brands well after 1975.

When Crown Prince Ludwig I of Bavaria was to celebrate his wedding in Munich in 1810, he decided it was an occasion for all of Bavaria to celebrate.
He commissioned Josef Pschorr, then the brewmaster of the Hacker-Pschorr brewery, among other Munich brewers, to develop special brews to commemorate the occasion.
