Yak butter (also known as "dri butter" or "su oil" Standard Tibetan: འབྲི་མར།, Chinese: 酥油) is butter made from the milk of the domestic yak (Bos grunniens). Many herder communities in China, India, Mongolia, Nepal, Gilgit-Baltistan Pakistan and Tibet produce and consume dairy products made from yak's milk, including butter. Whole yak's milk has about twice the fat content of whole cow's milk, producing a butter with a texture closer to cheese.[1][2] It is a staple food product and trade item for herder communities in south Central Asia and the Tibetan Plateau.
