Foz Torto produces wines from the Douro, the steep-terraced heart of Portugal's Duriense region in the north. The winery's portfolio centers on red blends built from the region's signature varieties: Tinta Roriz, Touriga Franca, Touriga Nacional, Tinta Francisca, and Alicante Bouschet. The Vinhas Velhas Tinto and Tinto showcase these grapes in different proportions, while a white expression, Vinhas Velhas Branco, rounds the range. The Douro's schist soils and continental climate produce wines of structure and depth—reds marked by dark fruit and tannin, whites by minerality and weight. Wine Advocate, Wine Enthusiast, and Decanter have all assessed Foz Torto's releases, with the Vinhas Velhas Branco and Vinhas Velhas Tinto among the highest-rated expressions in the lineup.
