Douro 101 Items Follow

The home of Port—perhaps the most internationally acclaimed beverage—the Douro region of Portugal is one of the world’s oldest delimited wine regions, established in 1756. The vineyards of the Douro, set on the slopes surrounding the Douro River (known as the Duero in Spain), are incredibly steep, necessitating the use of terracing and thus, manual vineyard management as well as harvesting. The Douro's best sites, rare outcroppings of Cambrian schist, are reserved for vineyards that yield high quality Port.

While more than 100 indigenous varieties are approved for wine production in the Douro, there are five primary grapes that make up most Port and the region's excellent, though less known, red table wines. Touriga Nacional is the finest of these, prized for its deep color, tannins and floral aromatics. Tinta Roriz (Spain's Tempranillo) adds bright acidity and red fruit flavors. Touriga Franca shows great persistence of fruit and Tinta Barroca helps round out the blend with its supple texture. Tinta Cão, a fine but low-yielding variety, is now rarely planted but still highly valued for its ability to produce excellent, complex wines.

White wines, generally crisp, mineral-driven blends of Arinto, Viosinho, Gouveio, Malvasia Fina and an assortment of other rare but local varieties, are produced in small quantities but worth noting.

With hot summers and cool, wet winters, the Duoro has a maritime climate.
