Continental in nature, with slight Atlantic influences. The winters are rather cold and the summers hot, although mention must be made of the significant difference in day-night temperatures contributing to the slow ripening of the grapes, enabling excellent acidity indexes to be achieved. The greatest risk factor in the region is the spring frosts, which are on many occasions responsible for sharp drops in production. The average annual rainfall is between 450 mm and 500 mm.


In general, the soils are loose, not very fertile and with a rather high limestone content. Most of the sediment is composed of layers of sandy limestone or clay. The vineyards are located on the interfluvial hills and in the valleys at an altitude of between 700 and 850 m.
