BeerBeer is an alcoholic beverage produced by the brewing and fermentation of starches from cereal grain—most commonly malted barley, although wheat, maize, rice, and oats are also used. The grain is mashed to convert starch in the grain to sugars, which dissolve in water to form wort. Fermentation of the wort by yeast produces ethanol and carbonation in the beer.
BarleyCereal grainBarley (Hordeum vulgare), a member of the grass family, is a major cereal grain grown in temperate climates globally. One of the first cultivated grains, it was domesticated in the Fertile Crescent around 9000 BC, giving it nonshatteringspikelets and making it much easier to harvest. Its use then spread throughout Eurasia by 2000 BC. Barley prefers relatively low temperatures and well-drained soil to grow.
CerealGrass that has edible grainHarvesting a cereal with a combine harvester accompanied by a tractor and trailer.Cereal grains: (top) pearl millet, rice, barley(middle) sorghum, maize, oats(bottom) millet, wheat, rye, triticaleA cereal is a grass (family Poaceae) cultivated for its edible grain. Cereals are the world's largest crops, and are therefore staple foods. They include rice, wheat, rye, oats, barley, millet, and maize (US: corn).
StarchStarch is a carbohydrate consisting of numerous glucose units joined by glycosidic bonds. This polysaccharide is produced by most green plants for energy storage. Worldwide, it is the most common carbohydrate in human diets, and is contained in large amounts in staple foods such as wheat, potatoes, maize (corn), rice, and cassava (manioc). Starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol.
FermentationFermentation is a type of anaerobic metabolism that harnesses the redox potential of the reactants to make adenosine triphosphate (ATP) and organic end products. Organic molecules, such as glucose or other sugars, are catabolized and their electrons are transferred to other organic molecules (cofactors, coenzymes, etc.).
SteepingSteeping is the soaking of an organic solid, such as leaves, in a liquid (usually water) to extract flavours or to soften it. The specific process of teas being prepared for drinking by leaving the leaves in heated water to release the flavour and nutrients is known as steeping. Herbal teas may be prepared by decoction, infusion, or maceration. Some solids are soaked to remove an ingredient, such as salt, where the solute is not the desired product.
YeastInformal group of fungiA yeast is any species of fungus that grows primarily in a unicellular form and reproduces via budding or fission. Yeasts are eukaryotic microorganisms that originated hundreds of millions of years ago, with at least 1,500 species currently recognized. They constitute about 1% of all described fungal species.
BreweryA brewery or brewing company is a business that makes and sells beer. The place at which beer is commercially made is either called a brewery or a beerhouse, where distinct sets of brewing equipment are called plant. The commercial brewing of beer has taken place since at least 2500 BC; in ancient Mesopotamia, brewers derived social sanction and divine protection from the goddess Ninkasi.
HomebrewingHomebrewing is the brewing of beer or other alcoholic beverages on a small scale for personal, non-commercial purposes. Supplies, such as kits and fermentation tanks, can be purchased locally at specialty stores or online. Beer was brewed domestically for thousands of years before its commercial production although its legality has varied according to local regulation.
MesopotamiaMesopotamia is a historical region of West Asia situated within the Tigris–Euphrates river system, in the northern part of the Fertile Crescent. It corresponds roughly to the territory of modern Iraq. Just beyond it lies southwestern Iran, where the region transitions into the Iranian plateau, marking the shift from the Arab world to Iran. Mesopotamia is the site of the earliest developments of the Neolithic Revolution from around 10,000 BC.
Ancient EgyptCradle of civilization in North AfricaAncient Egypt was a cradle of civilization concentrated along the lower reaches of the Nile River in the eastern part of North Africa. It emerged from prehistoric Egypt around 3150 BC (according to conventional Egyptian chronology), when Upper and Lower Egypt were united by Menes, who is believed by the majority of Egyptologists to have been the same person as Narmer.
ChinaCountry in East AsiaChina, officially the People's Republic of China (PRC), is a country in East Asia. It is divided into 33 province-level divisions, including two special administrative regions. Beijing is the capital, while Shanghai is the most populous city by urban area. Its geography features the Central Plain, major rivers such as the Yangtze and Yellow River, deserts, subtropical and temperate forests, plateaus, and mountain ranges such as the Himalayas.*As an Amazon Associate I earn from qualifying purchases.
