The production and processing area of DO Terra Alta (DOTA) is in the southern part of Catalonia between the River Ebro and the border with Aragon. It takes in the 12 towns in the county of la Terra Alta.
Its landscape retains all the characteristic features of an inland terroir close to the Mediterranean: pre-coastal limestone ranges (Ports d’Horta, Pàndols and Cavalls), small rivers (the Algars and the Canaletes), mountains of conglomerate rock, holm oak and white pine forests, and most of all agricultural soils painted with typical Mediterranean crops: almond trees, vines and olives.
Three clearly separate landscape features of agricultural interest can be added to this structure: la Plana, l’Altiplà and les Valls.
