Ontañón produces wines from Rioja, Spain's most celebrated red wine region. The winery works with the classic grapes of the area: Tempranillo, Graciano, and Garnacha. Its Altos de Ontañon Reserva, built on Tempranillo, has earned recognition from Wine Enthusiast, Wine Advocate, Wine Spectator, Decanter, and Falstaff. The Rioja Gran Reserva, made from Graciano, and Queirón El Arca Garnachas, sourced from Garnacha, have similarly impressed prestige critics. These wines reflect Rioja's tradition of age-worthy reds with structure and complexity, where extended oak aging and careful blending define the region's character.
