What actually happens, molecule by molecule, when food ferments. A plain-language walk through the chemistry, no lab coat required. The one-line version Microbes eat sugars and give back acids, gases and aromas. That, in a sentence, is fermentation. Everything that follows is just detail worth knowing. Meet the workers Different ferments rely on different microbes. Lactic acid bacteria drive kimchi and most vegetable ferments, turning sugars into lactic acid. Yeasts power kom

The bacteria and the yeasts work as a team: the yeasts turn sugar into alcohol and carbon dioxide, and the bacteria turn that alcohol into the tangy acids that make
