The Duero River is the same river as the Douro in Portugal. This region is notable for the rich white Verdejo of Rueda and the red wines of Toro, Ribera del Duero and Leon. The wine grape of Toro, called Tinta de Toro, has long been considered a mutant of Tempranillo. Ribera del Duero is home to one of the most famous wineries in Spain: Vega Sicilia.
