History of Beer

Beer is the world's oldest beverages, dating back to around the 6th millennium BC, and is recorded in the written history of ancient Egypt and Mesopotamia. The earliest Sumerian writings have a few references to beer. A prayer to the goddess Ninkasi known as "The Hymn to Ninkasi" serves as both a prayer as well as a method of remembering the recipe for beer in a culture with few literate people. The earliest known chemical evidence of beer dates to circa 3500–3100 BC from the site of Godin Tepe in the Zagros Mountains of western Iran. As almost any substance containing carbohydrates, namely sugar or starch, can naturally undergo fermentation, it is likely that beer-like beverages were independently invented among various cultures throughout the world. The invention of bread and beer has been argued to be responsible for humanity's ability to develop technology and build civilization. As for the close link between bread- and beer-making, women produced most beer prior to the introduction of hops in the thirteenth century, selling the beverage from their homes as a means of supplementing the family income. However, by the 7th century AD beer was also being produced and sold by European monasteries. During the Industrial Revolution, the production of beer moved from artisanal manufacture to industrial manufacture, and domestic manufacture ceased to be significant by the end of the 19th century. The development of hydrometers and thermometers changed brewing by allowing the brewer more control of the process, and greater knowledge of the results.
