Why does yogurt taste sour?
Plain and simple, yogurt is the result of bacterial fermentation of milk. All you need is pasteurized milk and bacteria. During this process, bacterial strains such as Lactobacillus and Bifidus — just two of the many types of lactic acid microorganisms — convert lactose sugars in milk into lactic acid. Standard starter cultures often number in the millions, and these little guys are active as hell; now you know why yogurt always contains “active culture” in the list of ingredients.
With such a high volume of active bacteria chugging away, the end result becomes supremely tangy. For some, that sour taste is anything but tasty, so many varieties of yogurt come adorned with additives ranging from honey to fruit preserves to balance out the flavor.
