Brewing Beer: Ancient Origins to Modern Craft (00:10–05:34)

Beer is one of humanity’s oldest beverages, dating back to at least 4,000 BC in Mesopotamia. Early versions were brewed without hops, relying on barley, wheat, rye, or grains and flavored with spices encountered during the Crusades. The introduction of hops in 15th-century Northern Europe shaped the modern beer flavor profile.
