Ribera del Duero is a Spanish Denominación de Origen Protegida located in the country's northern plateau and is one of eleven 'quality wine' regions within the autonomous community of Castile and León. It is also one of several recognised wine-producing regions to be found along the course of the Duero river.
The region is characterised by a largely flat, rocky terrain and is centred on the town of Aranda de Duero, although the most famous vineyards surround Peñafiel and Roa de Duero to the west, where the regional regulatory council or Consejo Regulador for the denominación is based.
Ribera del Duero was named Wine Region of the Year 2012 by Wine Enthusiast Magazine.
