The undisputed jewel in Portugal's crown is the beautiful wine region of Douro, located along the banks of the river from where it gets its name. The region itself is renowned around the world for its range of wonderfully aromatic fortified wines, as well as a wide variety of still red and white wines made from native grape varietals. Wineries in the Douro region utilize a huge amount of different local grapes for their characterful wines, but generally the most popular are made from Tinta Roriz, a rich and flavorful red wine grape related to Spain's flagship Tempranillo. However, there are plenty of different red and white grape varietals used in the region, all benefiting from the excellent hot weather and mineral rich terroir which characterizes the Douro valleys.
Portugal has been an important center for wine production ever since the Phoenicians and Carthaginians discovered that the many native grape varietals that grow in the country could be cultivated for making excellent wines. After all, Portugal has something of an ideal wine producing climate and terrain; lush green valleys, dry, rocky mountainsides and extremely fertile soil helped by long, hot summers and Atlantic winds. Today, such a climate and range of terroir produces an impressive variety of wines, with the best wines said to be coming out of the Douro region, the Alentejo and the Colares region near Lisbon. Portugal has an appellation system two hundred years older than France's, and much effort is made by regulating bodies to ensure that the quality of the country's produce remains high, and the wines remain representative of the regions they are grown in.
