Douro Wine Region
"The Paiz do Vinho, the home of the noblest vintages of port wine, embraces the mica-schist regions on the Douro (Baixo Corgo, Lower Douro), where the lighter varieties are produced, and the hilly country on both sides of the Corgo as far N. as Villa Real (Cima Corgo, Upper Douro), which yields the stronger vintages".--Baedeker 1913
