Castillo Labastida produces Tempranillo-based wines from Rioja, Spain's most prestigious red wine region. The winery's portfolio centers on the grape that defines the region: Tempranillo, which thrives in Rioja's continental climate and yields wines of structure and aging potential. The Aniversario 40, a pure Tempranillo expression, represents the winery's top offering. The range also includes a straightforward Tempranillo and a Crianza—a category that denotes oak aging and marks a step toward complexity. These wines have been assessed by major international critics including Wine Enthusiast, Decanter, Wine Advocate, and Wine Spectator. Rioja's tradition of blending old and new world techniques, combined with its limestone and clay soils, produces reds known for balance between fruit and tannin. Castillo Labastida's focus on single-varietal Tempranillo reflects the region's core identity.
