Hijos de Antonio Polo produces Tempranillo from Ribera del Duero, the Castilian region renowned for structured, age-worthy reds built on the Duero's continental climate and chalky soils. The winery's portfolio centers on two expressions: Aldealbar Reserva and Pagos de Peñafiel, offered in both Roble and Reserva formats. These wines reflect Ribera del Duero's signature character—dark fruit, firm tannin, and the mineral grip that defines the region's best bottlings. Wine Spectator, Falstaff, and Wine Advocate have rated the portfolio, with Aldealbar Reserva reaching 91 points and the Pagos de Peñafiel Roble at 90 points. The Reserva expression of Pagos de Peñafiel scores 89.3. Each wine is built on Tempranillo, the grape that anchors the region's identity and demands the extended aging that Reserva designation implies.
