The Alentejo is a region of gentle, flat plains, covering nearly a third of mainland Portugal. Only the Serra de São Mamede, to the north, stands out with its relief. The soils alternate between schist, clay, marble, granite, and limestone, offering great diversity. The climate is Mediterranean, hot and dry, with a strong continental influence.

The Alentejo has eight sub-regions: Borba, Évora, Granja-Amareleja, Moura, Portalegre, Redondo, Reguengos, and Vidigueira. Portalegre, with its granite predominance, is distinguished by the freshness of the Serra de São Mamede. Borba, Évora, Redondo, and Reguengos embody the Alentejo balance, while Granja-Amareleja, Moura, and Vidigueira, to the south, produce warmer and softer wines.

The main white grape varieties are Antão Vaz, Arinto, and Roupeiro, as well as Diagalves, Manteúdo, Perrum, and Rabo de Ovelha. The red varieties are Alfrocheiro, Alicante Bouschet, Aragonez, Castelão, and Trincadeira, as well as Moreto, Tinta Caiada, and Tinta Grossa.
