Beer is one of the oldest drinks humans have produced. The first chemically confirmed barley beer dates back to the 5th millennium BC in modern-day Iran, and was recorded in the written history of ancient Egypt and Mesopotamia and spread throughout the world.
The first solid proof of beer production comes from the period of the Sumerians around 4,000 BCE. During an archeological excavation in Mesopotamia, a tablet was discovered that showed villagers drinking a beverage from a bowl with straws. Archeologists also found an ode to Ninkasi, the patron goddess of brewing.
