Altún produces Tempranillo-based wines from Rioja, Spain's most prestigious red wine region. The winery's portfolio centers on three flagship expressions: Peñaquemada, Carralaguardia, and Crianza—each built from the region's signature grape. Rioja's continental climate, with Atlantic influences and high-altitude vineyards, shapes Tempranillo into wines of structure and aging potential. Wine Advocate and Wine Spectator have rated Altún's releases, with Peñaquemada earning particular recognition among the trio. The winery operates within a region defined by its commitment to traditional winemaking methods alongside modern precision, where oak aging and careful extraction define the category's character.
