Strained yogurt, Greek or Greek-style yogurt,[2] yogurt cheese, sack yogurt, kerned yogurt or labneh 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. Strained yogurt is made from milk, with the intermediate product being classic yoghurt, but it is concentrated by straining liquid off with cheese cloth or similar technique. In Europe and North America, it is often made from low-fat or fat-free cow's milk. In Iceland a similar product named skyr is made.
