What does fresh cow milk taste like?

Fresh cow's milk has a slightly sweet, creamy, and slightly tangy flavor. It has a full and rich mouthfeel, with a slightly grainy texture. The sweetness comes from the lactose, or milk sugar, present in the milk. The creaminess comes from the fat content, while the tanginess comes from the lactic acid produced by bacteria present in the milk. The grainy texture comes from the casein proteins in the milk.
