Reinheisgebot of 1516

The Reinheitsgebot of 1516 was a German law that regulated beer ingredients to ensure quality and safety. It allowed only barley, hops, and water in brewing; later, yeast was also accepted. This law aimed to prevent adulteration and protect consumers from harmful substances, while also controlling costs and maintaining traditional brewing standards. Over time, it became a cultural symbol of beer purity, especially in Germany, influencing brewing practices and beer appreciation worldwide.
