The main grape variety used in the Ribera del Duero Denominación de Origen (DO) is d. Tempranillo.

Ribera del Duero is a prominent wine region in Spain known for producing high-quality red wines. While it does allow other grape varieties, Tempranillo is the predominant grape, known for its robust flavor and aging potential. The region's climate, with its significant temperature variations between day and night, combined with the unique soil composition, helps enhance the characteristics of Tempranillo, offering wines that are rich, full-bodied, and often exhibit notes of dark fruit, spices, and oak when aged. This makes Tempranillo synonymous with Ribera del Duero wines and a primary choice for winemakers in the area.
