This grape variety is from Minho, where it is known by the name Vinhão, having migrated to the Douro region, where it has always been known as Sousão. It originates wines with dark and intense black color with some rudeness and brusqueness in the tannins and in the acidity. It is precisely these peculiar characteristics that made it so tempting in Douro where its colouring skills were quickly appreciated for the Port Wine.
