There is evidence to suggest that vines in the Douro Valley date back from 4 thousand years ago. Widely explored by the Romans in the first century AD the Douro vineyards are still expanding today.
The Douro Valley was the first in the world to be demarcated and regulated in 1756, and has been granted the acclaimed title of UNESCO World Heritage Site.
The region’s unique terroir is home to more than 120 varieties of grape. The Douro Valley extends through 250 thousand hectares of area (600.000 acres), 80km wide (50 miles), a difference in altitude of +/- 700 meters (more than 2million feet), and its the largest area of mountain vineyard on Earth.
