The Tempranillo grapes are sourced from vineyards planted in the foothills of the Cantabrian mountains, and from the lower course of the Najerilla river (near Uruñuela and Torremontalbo). The Garnacha vines are planted near the higher course of the Najerilla (near Badarán). Soil types are a combination of alluvial, sandstone-clay and ferrous-clay. The grapes are handpicked into 200kg crates and sorted by hand at the winery. After 3 days of pre-fermentative maceration at low temperature, the must undergoes daily remontage and delestage during temperature-controlled fermentation in cone-shaped stainless steel tanks. This is followed by 12 months maturation in, mostly new, American oak barriques.
