Portugal, a thin strip of land roughly the size of Indiana, is located on the Iberian Peninsula in Western Europe. Spain literally wraps around the northern and eastern borders while the cool Atlantic Ocean lies to the west. The temperate waters of the Gulf of Cadiz form the southern border. Although grapes are grown throughout the country, the most notable wine producing districts are located inland, away from the maritime influences of the Atlantic. The main red wine producing region in the north is the Douro Valley, best know for growing Touriga Francesa and Touriga Nacional, the two main varietals found in Port wines.
