Vinho do Douro
From Wikipedia, the free encyclopedia
The 'Douro wine (or Vinho do Douro), from the same region of Port Wines, were bitter wines but the English started adding Aguardente to it so that it would endure the voyage from Portugal to England. From then on the wine only got better and it appears by the first time in the registries of exports in 1679. Today's Douro wines are tasty table wines with some traits that remember a Port Wine.
