Alentejo is one of Portugal's wine regions and is divided into eight sub-regions: Portalegre; Borba; Redondo; Vidigueira; Reguengos; Évora; Granja-Amareleja and Moura. Renowned for its red wines, the Alentejo region gained visibility at the end of the 1980s, when consumer appreciation for the wine potential of this region grew, which has remained one of the most sought-after regions in Portugal to this day. The Alentejo is located between latitudes 38º and 39º north of the equator, in a region in central southern Portugal and includes the districts of Portalegre, Évora, Beja, half of the southern district of Setúbal and part of the district of Santarém. The Alentejo region is the largest in Portugal and has around 21,000 hectares of vineyards planted on predominantly gently sloping, low-yielding soils. Its topography is not very irregular, with three main mountain ranges: Serra de S. Mamede, Serra d'Ossa and Serra de Portel.
