Cepa 21 produces Tempranillo from Ribera del Duero, the prestigious wine region of Castilla y León in Spain. The winery's portfolio centers on this noble varietal, which thrives in the region's continental climate and limestone-rich soils. Horcajo, the flagship expression, demonstrates the depth and structure Ribera del Duero Tempranillo can achieve, followed by Malabrigo Ribera del Duero and the core Ribera del Duero Tinto. These wines have been assessed by Wine Advocate, Wine Spectator, Wine Enthusiast, and Decanter. Tempranillo from this region characteristically shows dark fruit, mineral tension, and aging potential—qualities reflected across Cepa 21's range.
