How does the terroir of the Douro Valley influence the production of Port wine?

The distinctive terroir of the Douro Valley truly rings the bell for the quality and character of Port wine. It is the other extremely rugged landscape with soils of schist character and vineyards which are terraced steeply, which prevent an excess of water, and ensure heat retention and consequential advantage to grapes in term of ripening and flavor concentration. The intense temperatures and very harsh and highly humid climate of the region results in superior grape quality which in turn makes Port wine produce the intense, rich flavors and complex aromas. Throughout the years, the terroir of Douro Valley has proved its adequacy for creating a legacy of the finest fortified wines in the planet.
