The grapes to make this wine are the Tempranillo variety grown on 25-year-old vines on our La Planta estate, which is at an altitude of 911 m (2,989 ft) in the Golden Mile of La Ribera del Duero at Quintanilla de Onésimo in the province of Valladolid. The estate is special because of its unusual chalky clay soil, with unfragmented bedrock just one metre below the surface.
