Strained yogurt, Greek yogurt, yogurt cheese, sack yogurt, or kerned yogurt is yogurt that has been strained to remove most of its whey, resulting in a thicker consistency than normal unstrained yogurt, while still preserving the distinctive sour taste of yogurt. Like many types, strained yogurt is often made from milk enriched by boiling off some water content, or by adding extra butterfat and powdered milk. In its places of origin, strained yogurt has two kinds of names: those which explicitly mention how it is made, meaning literally "strained" from Turkish Language or "hung" or "bag" yogurt; and those with a special name.
