Krohn produces Port wines from the Douro Valley's steep terraced vineyards, where granite soils and continental climate shape the character of the region's fortified wines. The winery draws on traditional Portuguese varieties—Touriga Nacional, Touriga Franca, Tinta Roriz, and Tinto Cao among the reds; Malvasia Fina, Codega de Larinho, and Gouveio among the whites—to craft expressions across the Port spectrum. Porto King's Port Blanc, a white Port made from aromatic white varieties, and Porto Jack's Port 10 Anos D'Age, a tawny aged in wood, represent the range. The Vintage Port, built from the region's dark-skinned varieties, captures the structure and aging potential that define the category. Wines from Krohn have been assessed by Wine Enthusiast, Wine Spectator, Falstaff, Wine Advocate, and Decanter.
