Hazaña produces Tempranillo-based wines from Rioja, Spain's most celebrated red wine region. The winery's portfolio centers on Tempranillo, the grape that defines Rioja's character—structured, age-worthy, and capable of expressing the region's varied terroir. Viñas Viejas, a pure Tempranillo, represents the winery's core expression, while Tradición blends Tempranillo with Graciano, the traditional Rioja complement that adds complexity and aromatic lift. Tinto rounds out the range as a straightforward Tempranillo offering. These wines have been assessed by Wine Advocate, Wine Enthusiast, and Decanter, establishing a presence among prestige critics. Hazaña's focus on Tempranillo reflects both regional tradition and the grape's natural affinity for Rioja's continental climate and varied soils.
