Buttermilk is a fermented dairy drink. It’s very common in warm climates where unrefrigerated milk turns sour quickly. Milk has naturally-occurring lactic acid that produces bacteria which causes the milk to ferment. This is traditional buttermilk and it’s still common in some countries.

In the United States, the buttermilk sold in stores is typically cultured buttermilk. It has been pasteurized, homogenized, and inoculated with several strains of bacteria to simulate the naturally-occurring bacteria in traditional buttermilk.
