La Rioja Alta is a renowned Spanish winery established in 1890 by five local growers in Haro, La Rioja. Over six generations, the winery has been dedicated to producing high-quality wines, specializing in red varieties such as Tempranillo, Mazuelo, Graciano, and Garnacha.

Their flagship wines include Gran Reserva 890 and Gran Reserva 904, named to commemorate significant dates in the winery's history. La Rioja Alta owns approximately 425 hectares of vineyards in the Rioja Alta region, ensuring control over grape quality.

The winery employs traditional winemaking techniques, including aging wines in American oak barrels crafted in their own cooperage. In addition to their Rioja operations, they have expanded to other prominent Spanish wine regions, owning wineries such as Torre de Oña in Rioja Alavesa, Lagar de Fornelos in Rías Baixas, and Áster in Ribera del Duero.
