<P> The Reinheitsgebot (German pronunciation: (ˈʁaɪnhaɪtsɡəboːt) (listen), 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 the states of the former Holy Roman Empire . The best - 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 . </P> <P> The most influential predecessor of the modern Reinheitsgebot was a law first adopted in the duchy of Munich in 1487 . After Bavaria was reunited, the Munich law was adopted across the entirety of Bavaria on April 23, 1516 . As Germany unified, Bavaria pushed for adoption of this law on a national basis (see Broader adoption). </P>
