evidence: In northern Portugal, Vila Real is a town in a hilly landscape, clinging to a headland far above the Corgo River. The Corgo is a tributary of the Douro and meanders down to the main stream through an epic landscape of terraced vineyards. [...] The Vila Real district is rooted in the port wine trade, and the closest wine lodges to the town are on the left bank of the River Corgo.
