The winegrowing region of Rioja is located in the Ebro Valley . It limits to the north with the Cantabria mountains and to the south with the Demanda mountains, what constitutes a privileged situation for the vine cultivation . The 57,000 hectares of vineyard included in the Denominación de Origen Calificada "Rioja" are distributed among the autonomous regions of La Rioja , Navarra and the País Vasco.
Different types of soils can be found: Clay-calcareous soils in terraces and small plots are located mainly in Rioja Alavesa, the Sonsierra and some zones of Rioja Alta; the clay-ferrous soils, are distributed in all the territory with vineyards situated in strong and reddish soils with deep and hard rock; while the alluvial soils are closed to the rivers and located in the flattest vineyard with the biggest plots, with deep soils formed by river stones named “cantos rodados”.
