While its area is quite vast, it has still only 2,000 hectares under vines.
The climate is continental with some Atlantic influences. The altitude is just under 900 metres. These are mainly rocky alluvial terraces, with a good drainage, poor in mineral salts but rich in calcium.
The typical grape here is Prieto Picudo, a red grape which one finds virtually nowhere else in Spain.
Very tannic, it makes well-structured wines.
