Evidence for brewing beer in Mesopotamia dates back to 3500-3100 BCE at the Sumerian settlement of Godin Tepe, an archaeological site in western Iran In 1992, archaeologists discovered chemical traces of beer in a fragmented jar dating to the mid-fourth century BCE. The same site also yielded evidence for early wine-making.
The Hymn to Ninkasi, the ancient Sumerian matron goddess of beer and alcohol, is probably the earliest surviving recipe for making beer. It's date is estimated at 1800 BCE. It is believed that recording the recipe in song or poetry may have served as a mnemonic for a people that was primarily illiterate. An English translation of the Hymn from the University of Oxford Electronic Text Corpus (ETCSLtranslation: t.4.23.1) reads as follows:
