Diez Caballero produces Tempranillo from Rioja, Spain's most celebrated red wine region. The winery's portfolio centers on three core expressions: Vendemia Seleccionada and Gran Reserva, both Tempranillo-based wines that have drawn attention from major critics including Wine Enthusiast, Wine Advocate, Wine Spectator, and Decanter; and Tempranillo Crianza, a more approachable entry point. Rioja's continental climate and varied terroirs—from clay and limestone soils to iron-rich deposits—shape the character of its Tempranillo, typically yielding wines with dark fruit, structured tannins, and aging potential. Diez Caballero's tiered range reflects the region's traditional classification system, offering versions suited to both near-term drinking and cellaring.
