Portugal is a relatively small but diverse wine producing nation. Apart from supplying most of the world’s cork, it also makes two of the world’s most popular fortified wines, Port and Madeira. With a wealth of indigenous varieties, varied geography and modern wine producing technology, Portugal is now exporting a selection of unique and interesting quality table wines. Climates have a big impact on the style of wine. Regions within a stone’s throw of the coast are heavily influenced by the moderating effects of the Atlantic Ocean, whereas slightly further inland, temperatures rise considerably and precipitation drops dramatically. Even between neighboring regions these differences have a big impact on the styles of wine made. The difference between the coastal region of Minho (responsible for light, spritzy, Vinho Verde) and the wines of the Douro (home of Port) is a case in point. Southern Portuguese regions such as the Alentejo are showing promise with native varietals, Castelão, and Trincadeira, and white skinned grapes such as Arinto.
