Zymology

Zymology, also known as zymurgy,[a] is an applied science that studies the biochemical process of fermentation and its practical uses.

Fermentation can be simply defined, in the context of brewing, as the conversion of sugar molecules into ethanol and carbon dioxide by yeast.

Si l'on me demandai en quoi consiste la réaction chimique par laquelle le sucre et décomposé … je l'ignore complètement.

The German Eduard Buchner, winner of the 1907 Nobel Prize in chemistry, later determined that fermentation was actually caused by a yeast secretion, which he termed 'zymase'.

The research efforts undertaken by the Danish Carlsberg scientists greatly accelerated understanding of yeast and brewing.
