The area of the designation of origin is diverse with varying geological and climatic characteristics. Its nexus is the middle basin of the river Segre, between the Pyrenees and the Ebro, and the inland, dry climate, which is far removed from any
maritime influences, is marked by an elevated insolation, sparse rainfall and persistent humidity from the winter fogs.
The vines are at an altitude of between 200 and 400 metres. The soil is calcareous and covered with sand and there is extreme uniformity throughout the designation.
The subzones of Artesa and Pallars are the most northerly, with vines of greater altitude and Pyrenean influences. Raimat, to the far east, enjoys a slight relief and a continental climate. The subzone of the Segrià, in the plain of Lleida, is characteristic of the dry lands. Garrigues and the Riucorb valleys are arid lands.
