Torre de Oña is the Rioja Alavesa winery that is part of the La Rioja Alta, S.A. group, the historic house based in Haro. It lies in Páganos, in the municipality of Laguardia, in Álava, in one of the appellation's most prestigious areas, sheltered by the Sierra de Cantabria.

The project was launched in 1995, when La Rioja Alta, S.A. decided to produce on this estate a high-quality wine capable of expressing its terroir. Since 2005, the work has focused on an in-depth understanding of the soils and individual parcels: each sub-parcel is vinified and matured separately, and the best grapes are reserved for the flagship wines.

In the vineyards, some of which lie close to the altitudinal limit for cultivation and are planted with century-old vines, Tempranillo and Mazuelo predominate. The estate features a neoclassical manor house among the vines, a stone cellar, and the Chapel of Santiago dating back to the 16th century. More recently, the Viñedos Artesanales project was launched, dedicated to reviving old vineyards over 50 years of age, with a new fermentation room equipped with small stainless-steel tanks.

The range, all DOCa Rioja, includes Finca San Martín, a pure Tempranillo from the vineyards surrounding the Páganos winery, Finca Martelo, and El Camino, the first wine from the Viñedos Artesanales project: a red based on Tempranillo from old bush-trained vines in Elvillar de Álava, aged for 14 months in 500-liter French oak barrels.

Tradition, the study of terroir, and respect for old vines make Torre de Oña one of the most authentic expressions of Rioja Alavesa.
