Olivier Rivière produces wines from Rioja that have drawn attention from major critics including Wine Advocate, Wine Enthusiast, Wine Spectator, and Decanter. The winery's portfolio centers on the region's classic varieties: Tempranillo, Grenache, and Graciano. Pozo Alto, a Grenache-based wine, represents the house's approach to the variety's potential in this terroir. Rioja Losares blends Graciano and Tempranillo, combining the latter's structure with Graciano's distinctive character. Arlanza El Quemado showcases Tempranillo alone. These three wines form the core of the winery's output, each capturing different facets of Rioja's expressive range. The wines reflect the region's continental climate and varied soil compositions, which shape the character of its reds across the Alta, Alavesa, and Baja subzones.
