Simon GmbH) is a large German brewery in Bitburg, Rhineland-Palatinate.

Founded in 1817 by Johann Wallenborn, its Pilsner is the third best-selling in Germany, and the nation's top-selling draught beer.

[2] Johann Peter Wallenborn (1784–1839) founded the brewery in Bitburg in 1817 at the age of 33.

[citation needed] Although Germans generally prefer local breweries, it is a popular beer throughout western Germany, and is favored in many areas of North Rhine Westphalia even over Alt beer or Kölsch, which are popular in Düsseldorf and Cologne.

In the 1970s, a second slogan was introduced, "Abends Bit, morgens fit" ("Bit in the evening, fit in the morning") implying that the consumption would not lead to a hangover.
