Bread and beer increased prosperity to a level that allowed time for development of other technologies and contributed to the building of civilizations.The product that the early Europeans drank might not be recognised as beer by most people today.Beer is brewed from cereal grains—most commonly from malted barley, though wheat, maize (corn), and rice are also used.During the brewing process, fermentation of the starch sugars in the wort produces ethanol and carbonation in the resulting beer.Brewing beer is subject to legislation and taxation in developed countries, which from the late 19th century largely restricted brewing to a commercial operation only.However, the UK government relaxed legislation in 1963, followed by Australia in 1972 and the US in 1978, allowing homebrewing to become a popular hobby.A company that makes beer is called either a brewery or a brewing company.

In 1516, William IV, Duke of Bavaria, adopted the Reinheitsgebot (purity law), perhaps the oldest food-quality regulation still in use in the 21st century, according to which the only allowed ingredients of beer are water, hops and barley-malt.

(The PPN is lasted from around 8500 BC to 5500 BC.) The earliest clear chemical evidence of barley beer dates to about 3500–3100 BC, from the site of Godin Tepe in the Zagros Mountains of western Iran.

During the building of the Great Pyramids in Giza, Egypt, each worker got a daily ration of four to five litres of beer, which served as both nutrition and refreshment that was crucial to the pyramids' construction.

Beer in South Korea must have less than 25% ABV, which means that it has to be 25 m L of alcohol or less per 100 m L of solution, and can be considered ‘lite’ only if it has less than 30 kcal per 100ml.

Additionally, beer in South Korea must use only water, hops, and starches (wheat, rice, barley, corn, or potato) as ingredients in the brewing process.
