Rías Baixas is a Denominación de Origen located in Galicia, northwestern Spain, established in 1988. The appellation takes its name from the coastal inlets called rías that characterize this Atlantic-facing region. It encompasses five sub-zones: Val do Salnés, Condado do Tea, O Rosal, Soutomaior, and Ribeira do Ulla, with Val do Salnés being the most significant for wine production.

The region's maritime climate is heavily influenced by the Atlantic Ocean, creating moderate temperatures and high humidity levels. Soils are primarily granite-based with good drainage, often mixed with sand and alluvial deposits near river valleys. Albariño is the dominant grape variety, required to comprise at least 70% of blends in most sub-zones, though it often appears as a varietal wine. Traditional training systems include the pergola-style parral, which elevates vines above ground level to improve air circulation in the humid climate.

Rías Baixas wines, particularly those made from Albariño, typically display bright acidity and mineral character reflecting their coastal terroir. The wines often exhibit citrus and stone fruit flavors, with saline notes that speak to their proximity to the Atlantic. These characteristics make them natural partners for the region's abundant seafood, and they generally show best when consumed young, though quality examples can develop complexity with several years of aging.
