Portuguese white grape variety grown mainly in bairrada, and dão, where it is called Borrado das Moscas, or fly droppings. The wines have good acidity and can be persuaded to display some aroma in some still varietal versions, although in Bairrada the grapes are often used in blends for sparkling wines. Some capacity for ageing has been demonstrated, Bical developing an almost riesling-like bouquet after a decade in bottle. It was grown on 1,456 ha/3,620 acres in 2010.
