Torre de Oña produces Tempranillo-based wines from Rioja, Spain's premier red wine region. The winery's portfolio centers on age-worthy expressions of the variety: Finca Martelo, a flagship that has drawn attention from Decanter, Wine Spectator, Wine Enthusiast, and Wine Advocate; Martelo Reserva, a more concentrated iteration; and Finca San Martín Crianza, an entry point to the house style. Rioja's continental climate and alluvial soils favor Tempranillo's natural structure and aging potential, qualities evident across Torre de Oña's range. The wines reflect the region's tradition of oak-influenced reds built for cellaring, with the depth and balance that define serious Rioja.
