The yeast Saccharomyces cerevisiae is found in beer, wine, and bread, but also in research laboratories, as it is the organism that initiated modern biochemistry and molecular biology and remains a fundamental testing ground for science.
Fermentation is the heart of the beer brewing process: through it, wort made from malted grains is transformed into alcohol and carbon dioxide by yeast. Beer fermentation is generally divided into three stages: primary fermentation, secondary fermentation, and conditioning.
