Portuguese wine was mostly introduced by the Romans and other ancient Mediterranean peoples who traded with local coastal populations, mainly in the South. In pre-Roman Gallaecia-Lusitania times, the native peoples only drank beer and were unfamiliar with wine production. 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 regions 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 big variety of local kinds, producing a very wide variety of different wines with distinctive personality. History In southern Iberian Peninsula, some archeological finds attest that the consumption of wine occurred around the 7th to the 6th century B.C. and production started in the 5th to the 4th century B.C. Romans did much to expand and promote viticulture in their settlements in the province of Lusitania, most especially Portuguese Estremadura and the south of Portugal. In Northern Portugal, and according to the current knowledge, wine-making started with Roman rule. Strabo notices that the indigenous peoples in Northern Portugal mostly consumed zhytos (a form of beer) and wine was rarely produced or consumed; the wine, of low production, was immediately consumed in family banquets, all orderly sited and consuming by age and status, proving that wine was a fascination to them. Wines were then produced across the territory for both local consumption as well as export to Rome. During the Reconquista in the 12th and 13th centuries, with the populating (povoamento) of the conquered territories, areas due to religion the Arabs reduced wine production. During this period, some new varieties were added to the ancient ones, from Burgundy came the French varieties. And during the period of discoveries, Henry the Navigator brought to the newly discovered island of Madeira the Moscatel and Malvasia from the Greek Island of Crete. In the Reign of King Carlos, the Região Demarcada do Vinho Verde and the Região Demarcada do Dão among Colares, Carcavelos, Setúbal, and Madeira were created. In 1979, Bairrada was added and in 1980
