The grapes for this wine come from proprietary vineyards in San Vicente de la Sonsierra and Laguardia, at an altitude of 1,860 ft. above sea level. Soils are calcareous clay with gravel. The wine undergoes 8 days of maceration during fermentation with two daily pump-overs. After alcoholic fermentation, it undergoes an extended maceration of 17 days with reduced frequency of pump-overs to avoid the extraction of bitter characters. Aged for 6 months in tanks and another 6 months in 2-3 year-old Bordelaise barrels of American and French oak.
The Sierra Cantabria mountain range (1,200 m. of altitude) and the river Ebro (350 m.), create a special microclimate with Mediterranean and Continental characteristics -providing mild winters and gentle summers- unique for vine cultivation. The landscape of the vineyard is characterized by the influence by both the mountain range Sierra de Cantabria and the depression of the Ebro River, creating a soft and wavy relief, which faces south to south-southwest, thus allowing more sunlight hours to reach the plants and enhance the maturation of the grapes.
The soils, of calcareous-clay composition and poor in organic matter, nutrients and minerals, are very suitable for grape growing. Whilst, the abundance of boulders, remnants of alluvium material and gravel, gives optimal drainage and water retention. In the subsoil cracked rocks are found which aid the search for additional nutrients by the vine roots and therefore favoring the balance of the fruit.
