Luis Seabra works in the Douro, the steep-terraced heart of Portugal's northern wine country. The winery's portfolio centers on indigenous varieties that thrive in the region's schist soils and continental climate. Xisto Cru Branco blends Rabigato, Gouveio, and Codega de Larinho into a white of mineral precision. Indie Xisto Tinto draws from five regional red varieties—Touriga Franca, Tinta Amarela, Tinta Barroca, Tinta Roriz, and Rufete—layering the complexity the Douro is known for. Mono C Castelão offers a single-varietal expression of Castelão, the dark-skinned grape native to Portugal's Atlantic-facing regions. Wine Spectator, Wine Advocate, and Decanter have all rated these wines.
