Beer

Beer is one of the oldest alcoholic drinks in the world. There is some evidence that beer was produced as early as 6000 B.C, a full 2000 years before the invention and use of the wheel in 4000 B.C. Proven records of beer produced from barley dates to about 3500–3100 B.C. in the Zagros Mountains of western Iran, but unproven estimates date back even further to about 10,000 B.C., when cereal was first farmed. Archaeologists speculate that beer was instrumental in the formation of civilizations.
