Federico Paternina produces wines from Rioja, Spain's most prestigious red wine region. The winery works primarily with Tempranillo, the backbone of classical Rioja, and Graciano, a traditional regional variety that adds structure and complexity. Clos Rioja Reserva, a blend of Graciano and Tempranillo, represents the winery's approach to age-worthy reds, as does Conde de los Andes Gran Reserva, a Tempranillo-based expression. Tempranillo Castilla offers a more direct encounter with the region's signature grape. These wines have been assessed by major critics including Wine Spectator, Wine Enthusiast, Falstaff, and Decanter.
