Yak butter

Yak butter is butter made from the milk of the domesticated yak (Bos grunniens). It is a staple food item and trade item for herding communities in south Central Asia and the Tibetan Plateau. Many different political entities have communities of herders who produce and consume yak's dairy products including cheese and butter – for example, China, India, Mongolia, Nepal, and Tibet.

Whole yak's milk has about twice the fat content of whole cow's milk, producing a butter with a texture closer to cheese.

Production

Yaks provide their herders with many different benefits, including dung for fuel, draught power, meat, fiber, and milk. Not all herding communities have a tradition of using yak's milk or making butter, although in regions of mountain pastures the practice is common. Each individual yak cow produces little milk, so only when large herds are present can herders expect much milk to be obtained. Milk is much more plentiful in summer than winter; turning fresh milk into butter or cheese is a way to store calories for later use.
