Established in 1964 by a group of local growers, this 160 hectare estate is named after the best plots in the Rioja Alavesa. Its unique position, where the River Ebro is closest to the Sierra Cantabria mountains, provides a blend of continental and Mediterranean climates, preventing an excess of extreme cold and rain. The poor soils, a base of shallow limestone, help limit the yield and provide grapes of great concentration and colour. In addition, the majority of the vineyards lie between 450-550 metres above sea level, meaning cooler nights and thus a greater retention of natural acidity in the grapes. The wines are fermented in stainless steel tanks before spending between 4-18 months in French and American oak, depending on the designation.
