The process of fermentation is used to make various products, primarily food and beverages, through the conversion of sugars into acids, gases, or alcohol by microorganisms, primarily yeast and bacteria. This process is widely used in producing alcoholic beverages like beer and wine, as well as in the making of bread, yogurt, and pickled foods. Fermentation not only enhances the flavor and preservation of these items but also provides health benefits, such as probiotics in yogurt. The versatility of fermentation makes it an essential practice in culinary traditions around the world.
