Sitting in the southwestern corner of Europe, in Iberian Peninsula, Portugal is the seafaring nation that discovered so much of the new world without ever losing sight of the old, in its ancient culture and wine tradition.
In wine producing countries and in the greatness of the wine world, Portugal is better known by the cork industry, being its dominant producer, than for its wines. However, there is an inner world in Portuguese wine, its legion of indigenous grape varieties explained by the diversity of terroirs. For this reason and for such a small nation, there is an impressive diversity of wines. The Atlantic Ocean influences the fresh and crisp wines produced on the flat littoral coast. In the mountain ranges north of Oporto, rainfall reaches 2000 mm / year being strongly different from the 500 mm / year that occurs in some inland areas influenced by the continental dryness coming from east. The temperate maritime climate characterized by warm summers and cool, wet winters, turn more extreme on the direction of south and east, with an average annual temperature of around 10 ºC in the northern hills contrasting with more than 17.5 ºC on the southern plains, where, temperatures frequently exceed 35 ºC in summer days .
As a result of this dissimilar climate circumstances, two neighbouring vineyards growing the same grape can produce quite distinct wines. As an example of it, two of the most famous type of wines in the world known as Vinho Verde and Port are produced in contiguous regions. This phenomenon happens all over Portugal and that’s why other foreign varieties adapted so well.
