You may be familiar with the phrase fermentation and believe it has something to do with brewing or bacteria. In truth, Fermentation is an essential step in producing foods, including bread, beer, wine, and cheese. Probiotics, or helpful bacteria that aid digestion, are also produced by some types of Fermentation. It’s important to note that Fermentation is not the same as pickling.
Humans had fermented food since the Neolithic period, long before anyone understood fermentation science.
