Port and still wine can be made from more than 80 different grape varieties, but in practice the vineyards are dominated by five key varieties; Touriga Nacional, Touriga Franca, Tinta Barroca, Tinto Cao and Tinta Roriz (Tempranillo). Of these, aromatic Touriga Nacional is the most highly regarded, and Touriga Franca the most widely planted. Vineyards tend to be an eclectic cross-section of port grape varieties, often with more than 20 present within a single vineyard.
Douro table wines are typically made from the same grape varieties as their esteemed port cousins, but a number of international varieties have also found a home in the valley. Cabernet Sauvignon, Sauvignon Blanc and Gewurztraminer are among the more common non-native grapes planted here.
