The Tempranillo comes from old proprietary vineyards in San Vicente de la Sonsierra of the Rioja DOCa, and were all planted before 1980 upon calcareous clay with gravel. The fruit is entirely hand-harvested before a careful selection occurs on a double sorting table. Fermentation occurs under temperature control vessels with indigenous yeast, before the wine ages for 24 months in French and American oak, of which 25% is new.
