The Douro region in northern Portugal stands as the cradle of Port wine, owing its name to the winding Douro River that traverses from east to west, flowing into the Atlantic Ocean in Oporto. Renowned for Port and its unique still Douro wines, this area features a rugged terrain with diverse terroirs defined by varying aspects, altitudes, and soils. Its vineyards, perched on steep, arid slopes and narrow rocky terraces alongside the river and its tributaries, offer a UNESCO World Heritage landscape akin to Austria's Wachau wine region.
Douro's fame extends to its array of indigenous grape varieties. Red varieties such as Sousão and Tinta Amarela (Trincadeira), alongside white counterparts like Malvasia Fina, Moscatel, Rabigato, Gouveio, and Viosinho, contribute significantly. Notable grapes like Tinta Barroca, Tinta Roriz, Tinto Cao, Touriga Franca, and Touriga Nacional play pivotal roles, especially in Port production. Presently, the Douro produces esteemed red table wines from its diverse native grape varieties. The region's diversity and indigenous varietals underscore its esteemed status in the global wine landscape.
