Beer is one of the world’s oldest beverages, with the history of beer dating back to the 6th millennium BC, and being recorded in the written history of Ancient Iraq. The earliest Sumerian writings contain 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.
As almost any substance containing carbohydrates, mainly 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.The earliest chemically confirmed barley beer to date was discovered at Godin Tepe in the central Zagros Mountains of Iran, ca. 3400-3000 B.C. (Chalcolithic/Late Uruk Period).
Beer may have been known in Neolithic Europe as far back as 3000 BC, and was mainly brewed on a domestic scale.
Beer produced before the Industrial Revolution continued to be made and sold on a domestic scale, although 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.
Today, the brewing industry is a global business, consisting of several dominant multinational companies and many thousands of smaller producers ranging from brewpubs to regional breweries. More than 133 billion liters (35 billion gallons) are sold per year—producing total global revenues of $294.5 billion in 2006.
