Buttermilk is a fermented dairy drink. Traditional buttermilk is the liquid leftover after whole milk has been churned into butter. This type of buttermilk is rarely found in Western countries today but remains common in parts of Nepal, Pakistan, and India. Buttermilk today consists mostly of water, the milk sugar lactose, and the milk protein casein. Buttermilk is thicker than milk. When the bacteria in the beverage produce lactic acid, the pH level is reduced, and casein, the primary protein in milk, solidifies.
