German Beer Purity Act

The German Beer Purity Act, known as the Reinheitsgebot, was enacted in 1516 to regulate beer ingredients. It primarily allowed only water, barley, and hops in beer, with yeast added later once its role was understood. The law aimed to ensure quality, prevent adulteration, and control costs. Over time, it became a symbol of brewing tradition and purity in Germany. Today, modern regulations have evolved, but the Reinheitsgebot remains a historic milestone emphasizing the importance of quality ingredients and craftsmanship in beer brewing.
