The Ribera del Duero is a wine-making region of northeast central Spain, mostly split across the province of Burgos and province of Valladolid, both of which are part of the autonomous community of Castile-Leon. It is where the renowned Vega Sicilia wines are made, probably the most famous wine-maker in the region. Pesquera is a town in the Ribera del Duero region that is noted for its excellently balanced red wines. However the area around La Horra, another small town in the region, is respected by locals for its consistently great wines. Viña Sastre is one of the wine makers in this area.
