Reinheitsgebot

The Reinheitsgebot (, literally "purity order"), sometimes called the "German Beer Purity Law" in English, is the collective name for a series of regulations limiting the ingredients in beer in Germany and its predecessor states. The most well-known version of the law was adopted in Bavaria in 1516, but similar regulations predate the Bavarian order, and modern regulations also significantly differ from the 1516 Bavarian version.
