Name the German beer purity law which stipulates that beer must include only hops, barley, water, and yeast.

The Reinheitsgebot is a set of rules set in Germany and the former Holy Roman Empire that restrict the ingredients allowed in beer. Although the most famous form of the legislation was enacted in Bavaria in 1516, comparable restrictions precede the Bavarian order.
