Fermentation

Fermentation (Beer)

Fermentation is a chemical process that makes sugars like glucose transform into acids, gases, or alcohol (beer,wine). Fermentation occurs in yeast and bacteria, as well as inside our muscles when oxygen is insufficient, as in the case of lactic acid fermentation. The way beer is made is by germinating grains by soaking them in water, where amylase enzymes break down endosperm starches into sugar. Depending on what type of flavor is desired, germination is halted at certain points and the grain is dried to create malt through a process called kilning. The malt is then grounded and mixed with water to complete the liberation of sugars.
