Reinheitsgebot

The Reinheitsgebot, or "German Beer Purity Law," was enacted in 1516 and regulates the ingredients used in brewing beer. Originally, it allowed only water, barley, and hops, ensuring high-quality and safe products. Yeast was later included as a necessary ingredient after its role in fermentation was understood. This law aims to preserve traditional brewing methods and protect consumers from harmful additives. While not legally binding today, it remains a strong symbol of German beer culture and craftsmanship, emphasizing purity and quality in brewing practices.
