Portuguese wine is the result of traditions introduced to the region by ancient civilizations, such as the Phoenicians, Carthaginians, Greeks, and mostly the Romans.
Portugal started to export its wines to Rome during the Roman Empire. Modern exports developed with trade to England after the Methuen Treaty in 1703. From this commerce a wide variety of wines started to be grown in Portugal. And, in 1758, one of the first wine-producing region of the world, the Região Demarcada do Douro was created under the orientation of Marquis of Pombal, in the Douro Valley.
Portugal has two wine producing regions protected by UNESCO as World Heritage: the Douro Valley Wine Region (Douro Vinhateiro) and Pico Island Wine Region (Ilha do Pico Vinhateira). Portugal has a large variety of native breeds, producing a very wide variety of different wines with distinctive personality.
