Caiño Tinto is a dark-skinned grape variety used to make fragrant red wines in the west of the Iberian Peninsula (Spain and Portugal). It is primarily grown in Galicia, and in particular Rias Baixas and Ribeiro, where it is used predominantly in red wine blends that range from delicate and perfumed to medium bodied and very sour. In Portugal, Caino Tinto is known as Borraçal and is used as a blending agent in the zingy red wines of Vinho Verde.
