Fermentation is a metabolic process that converts sugar to acids, gases, and/or alcohol. It occurs in yeast and bacteria, and also in oxygen-starved muscle cells, as in the case of lactic acid fermentation. Fermentation is a process that has been used by humanity to preserve foods, changing chemical structure and taste, for millennia. Pickles, wine, beer, bread and much more are made using fermentation.
