Beer is the world's oldest and most widely consumed alcoholic drink; it is the third most popular drink overall, after water and tea. The production of beer is called brewing, which involves the fermentation of sugars, mainly derived from cereal grain starches—most commonly from malted barley, although wheat, maize (corn), and rice are widely used. Most beer is flavoured with hops, which add bitterness and act as a natural preservative, though other flavourings such as herbs or fruit may occasionally be included. The fermentation process causes a natural carbonation effect, although this is often removed during processing, and replaced with forced carbonation. Some of humanity's earliest known writings refer to the production and distribution of beer: the Code of Hammurabi included laws regulating beer and beer parlours, and "The Hymn to Ninkasi", a prayer to the Mesopotamian goddess of beer, served as both a prayer and as a method of remembering the recipe for beer in a culture with few literate people. https://en.wikipedia.org/wiki/Beer
