Purity Law

The Purity Law, originally known as the "Reinheitsgebot," was a regulation in 16th-century Germany that set strict standards for beer ingredients. It allowed only barley, hops, and water—later yeast was recognized—as legitimate ingredients, preventing the use of other grains or additives. The law aimed to ensure beer quality and safety. Today, it symbolizes traditional brewing standards, emphasizing natural ingredients and purity in beer production, and has influenced modern brewing regulations worldwide.
