Campo Viejo produces wines from Rioja, Spain's most celebrated red wine region. The winery works primarily with Tempranillo, the backbone grape of the region, alongside traditional varieties like Graciano and Mazuelo. Its Dominio blend—a combination of Graciano, Tempranillo, and Mazuelo—represents the winery's approach to the region's classic style. The Tempranillo and Gran Reserva offerings further demonstrate a focus on the variety that defines Rioja's character: structured, age-worthy reds with earthy depth and balanced tannin. Wines from Campo Viejo have been assessed by major critics including Decanter, Wine Spectator, Wine Advocate, Wine Enthusiast, and Falstaff.
