Barco de Piedra is located in the heart of the western district of Ribera del Duero, about a mile north of the Duero River and 4 miles east of Vega Sicilia. The wines are made from organic, estate fruit grown on the hillsides of the Quinon Estate. Of the two main growing areas in Ribera, the west side, where El Quinon is located, is not as exposed to frost and enjoys more moderate temperatures. Cool nights, minimal rain and older vines produce small berries with a high skin-to-juice ratio and strong tannins, thereby diminishing the need for oak.
At harvest, the fruit is sorted, de-stemmed and macerated on its skins for 2-3 days at cool temperatures for 11 days with an additional eight days of post-fermentation. The wine aged for five months in neutral 300-liter French oak (85%) and French and American oak barrels (15%).
