What beverage dates back to 5th millienium and has some of the oldest recipes written in Summerian
Brewing methods Beer is produced through steeping a sugar source (commonly malted cereal grains) in water and then fermenting with yeast. Brewing has taken place since around the 6th millennium BC, and archeological evidence suggests that this technique was used in ancient Egypt. Descriptions of various beer recipes can be found in Sumerian writings, some of the oldest known writing of any sort. Brewing is done in a brewery by a brewer, and the brewing industry is part of most western economies.
Aspergillus oryzae Aspergillus oryzae, known in English as koji (Japanese: 麹 , Hepburn: kōji ) , is a filamentous fungus (a mold) used in Chinese and other East Asian cuisines to ferment soybeans for making soy sauce and fermented bean paste, and also to saccharify rice, other grains, and potatoes in the making of alcoholic beverages such as "huangjiu", "sake", "makgeolli", and "shōchū". The domestication of "A. oryzae" occurred at least 2000 years ago. "A. oryzae" is also used for the production of rice vinegars.
