The Douro valley in Portugal has long been one of Europe's most important and unique wine regions, with a history which stretches back over two thousand years to when Pheonician tradesmen and settlers first began planting grapevines in the rich and fertile soil found there. The region itself is something of an ideal location for viticulture, with mineral rich soils and plenty of moisture from the river, alongside long, baking hot summers which help the grapes reach full ripeness. Wineries in the Douro utilize a wide range of grape varietals for their distinctive and characterful wines, including red varietals such as Tinta Barroca, Tinta Roriz and Tinta Cao, and delightful white varietals such as Gouveio and the increasingly popular Viosinho. However, it is for the fortified wines of Porto which Douro is most famous for, and these are widely considered to be amongst the finest fortified wines in the world.
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.
