The name came from the observation that mixtures of crushed grapes kept in large ... to decipher the nature of alcoholic fermentation through analytical chemistry and chemical nomenclature.

During traditional fermentation, grape juice evolves ... “I was dealing with crazy sorts of chemistry with these grapes; the pH was perfect but the malic acid was wild.” With carbonic ...

Wine, of course, is made by the process of fermentation: Yeast converts grape sugar to alcohol, and the end result is this glorious liquid we love. One of the byproducts of fermentation is heat ...

The kick-start of yeasts: Yeasts convert grape sugar into alcohol, beginning the fermentation process. And there are two types of yeasts — ambient and cultured. Ambient yeasts are sometimes ...
