Nestled in the extreme northwest of Spain, Rias Baixas is a wine region that is located in the province of Pontevedra and south of A Coruna, in Galicia. Rias Baixas is known for white wine, produced from the Albariño grape variety.

Historians believe that the grapes were introduced to Rias Baixas around the 12th century by the Cistercian monks when they established the Monastery of Armeteira. The five sub-regions, Condado do Tea, Soutomaior, Ribera de Ulla Val do Salnés and O Rosal; also have a long history of wine production with their own traditional styles. The sub-regions have different soil types and range from sandy to alluvial, granite and slate.

Rias Baixas has an Atlantic climate with sea fog and wet winters. The average rainfall is high with mild temperatures. During the summer, temperatures rarely exceed 86°. The coldest areas in the regions are Val do Salnés and Ribera de Ulla, because of their coastal location. Condado do Tea is the warmest, but also the coldest with heavy rainfall and frequent frosts.  

Rias Baixas white grapes that are authorized include Albariño, Loureira Blanca, Treixadura, Caiño Blanca, Torrontés and Godello. The red authorized varieties are Caiño Tinto, Espadeiro, Loureira Tinta, Sousón, Mencía and Brancellao.
