The Purity Law (Reinheitsgebot)

The Purity Law, or Reinheitsgebot, was established in 1516 in Bavaria to regulate beer ingredients. It primarily allowed only water, barley, and hops in brewing, with yeast later added once its role was understood. The law aimed to ensure quality, prevent adulteration, and control prices by restricting harmful or cheap ingredients. Over time, it became a symbol of brewing tradition and quality control, influencing beer standards in Germany and beyond. Today, modern regulations have relaxed some restrictions, but the Reinheitsgebot remains a historical reference to Germany’s commitment to purity and craftsmanship in brewing.
