Maritávora produces wines from the Douro, Portugal's steep-terraced river valley in the north. The winery works with the region's traditional varieties: white grapes like Codega de Larinho, Rabigato, and Viosinho; reds including Tinta Roriz, Touriga Franca, and Touriga Nacional. The Grande Reserva Old Vines Branco, a blend of Codega de Larinho, Rabigato, and Viosinho, stands as the flagship, rated by Wine Spectator, Wine Enthusiast, Wine Advocate, and Decanter. The Reserva Branco and Reserva Tinto follow, both drawing on the same varietal palette that defines Douro winemaking. These wines reflect the region's continental climate, schist soils, and the intensity that comes from old-vine fruit in one of Portugal's most demanding terroirs.
