High Quality Content by WIKIPEDIA articles! Strained yoghurt, yoghurt cheese, labneh, or Greek yoghurt is yoghurt which has been strained in a cloth or paper bag or filter to remove the whey, giving a consistency between that of yoghurt and cheese, while preserving yoghurt`s distinctive sour taste. Like many yoghurts, strained yoghurt is often made from milk which has been enriched by boiling off some of the water content, or by adding extra butterfat and powdered milk. However most strained Greek yogurts have no added fats and are made of real milk.
