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 big variety of local kinds, producing a very wide variety of different wines with distinctive personality.
Romans did much to expand and promote viticulture in their settlements in the province of Lusitania (mainly modern south Portugal). Wines were 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 the Algarve region (Lagoa, Lagos, Portimão, and Tavira) was finally demarcated. In 1998, the Alentejo region was demarked by the gathering several smaller demarked regions created in 1995.
Portugal has a large array of native varietals, producing an abundant variety of different wines. The wide array of Portuguese grape varietals contributes as significantly as the soil and climate to wine differentiation, producing distinctive wines from the Northern regions to Madeira Islands, and from Algarve to the Azores. In Portugal only some grape varietals or castas are authorized or endorsed in the Demarcated regions, such as:

Vinho Verde : This region is mainly in the Minho province and is in the extreme north-west of Portugal. There are six areas : Monção, Lima, Braga, Penafiel, Basto and Amarante.
Vinho Verde derived its name from the fact that the grapes used are ‘green’ meaning slightly under-ripe. Vinho Verde wines are now largely exported, and are the most exported Portuguese wines after the Port Wine. The most popular variety in Portugal and abroad are the white wines, but there are also red and more rarely rosé wines. A notable variety of Vinho Verde is Vinho Alvarinho which is a special variety of white Vinho Verde, the production of Alvarinho is restricted by EU law to a small sub-region of Monção, in the northern part of the Minho region in Portugal. It has more alcohol (11.5 to 13%) than the other varieties (8 to 11.5%).
Douro wine (Vinho do Douro) originates from the same region as port wines. In the past they were considered to be a bitter tasting wine. In order to prevent spoilage during the voyage from Portugal to England, the English decided to add a Portuguese wine brandy known as aguardente. The first documented commercial transactions appearing in registries of export date as far back as 1679. Today’s Douro table wines are enjoying growing favor in the world, maintaining many traits that are reminiscent of a port wine.
Dão wine is from the Região Demarcada do Dão, a region demarcated in 1908, but already in 1390 there were taken some measures to protect this wine. The Dão Wine is produced in a mountainous region with temperate climate, in the area of the Mondego and Dão Rivers in the north region of central Portugal. These mountains protect the castas from maritime and continental influences.
Bairrada wine, is produced in the Região Demarcada da Bairrada. The name “Bairrada” is from “barros” (clay) and due to the clayey soils of the region. Although the region was classified in 1979, it is an ancient vineyard region. The vines grow exposed to the sun, favouring the further maturity of the grapes. The Baga casta is intensely used in the wines of the region. The Bairrada region produces table, white and red wines. Yet, it is notable for its sparkling natural wine.
Alentejo wine is produced from grapes planted in vast vineyards extending over rolling plains under the sun which shines on the grapes and ripens them for the production. Some producers of this region still do wine in great potteries as in Roman times.
Colares wine is type of wine produced in sandy soils outside Lisbon between the foothills of Sintra and Roca Cape. Because of Lisbon’s urban sprawl, the lands available for vineyards became so small, that the demands has always been higher than the production, making it one of the most expensive Portuguese wines.
