Skeffington produces Port wines from the Duriense region of northern Portugal, where the steep schist terraces and continental climate shape the character of the wines. The winery's Vintage Port draws from a blend of classic Porto varieties—Touriga Nacional, Tinta Cão, Touriga Franca, Tinta Barroca, and Tinta Roriz—grapes prized for their depth and aging potential. The Late Bottled Vintage Port follows a similar varietal foundation, offering a more accessible expression of the region's traditional style. Both wines have been assessed by major critics including Wine Advocate, Falstaff, Wine Enthusiast, Decanter, and Wine Spectator. The Vintage Port, in particular, reflects the intensity and structure that define the finest Ports from this storied region.
