The Douro Valley in Portugal—a DOC traditionally known for its production of Port wine—increasingly is becoming known for its unfortified wines, bottles that celebrate the valley's unique terroir and continued use of traditional grapes. The oldest demarcated region for wine production in the world, the Douro Valley is one of those anomaly wine regions whose climate changes from east to west, not north to south. To the west is the Lower Corgo, more influenced by the wet, cool Atlantic, and in the center is the Upper Corgo, the largest of the three sub-regions and home to most of the better-known quintas, or wine houses. Furthest east is the Douro Superior, with more continental weather (extremely hot summers, extremely cold winters) and the smallest amount of viticulture of the three regions. Interestingly, Porto itself has a climate unsuitable for growing grapes, but perfect for storing wines due to its cool and humid conditions.

Quinto do Crasto Reserva Old Vines, Douro, 2009: A blend of more than 25 grape varieties (the older vineyards are a mix of different vines), certain to include some of the "top cinco:" Touriga Nacional for structure; Touriga Franca for bouquet and length of finish; Tinta Roriz, known as Tempranillo in Spain; Tinto Cấo, with low yields but great concentration of flavor and spicy bouquet; and Tinta Barroca, a robust grape to add fullness to blends. The Reserva is an example of brilliant blending, characterized by mature soft tannins with a strong, fruity finish. ($36 retail)
Quinta Vale D. Maria, Van Zellers White, Douro, 2010: A blend of Viosinho, Rabigato, Codega, and Gouveio, with vines from 30 to 80 years old. More floral than citrus with pleasant spring hints of grass, the mouthfeel is round with an almond richness and a refreshing mellow citrus on the finish. ($16 retail)
Niepoort, Vertente, Douro, 2008: A blend of many grapes lends a dark ruby robe, elegant and light on the nose, but full of baked red fruit, like raspberry pie, on the palate. Although rich in minerality, spice, and lush tannins, here the fruit sings loudest. ($27 retail)
Quinta do Vallado Reserva Field Blend, Douro, 2009: Mostly old vines and more than 20 grape varieties, including Tinta Roriz, Tinta Amarela, and Touriga Franca. Surprisingly big for such a young wine, due to the complex soil and old vines. Mellow and rich earth notes are balanced by baked fig and plum fruit on the palate. ($65 retail)
Quinto do Vale Meão Vintage Port, 2008: Rich tannins, yet somehow lightly refreshing for a Port; black and red fruit stand out in the loamy soil notes. A blend of Tinta Barroca, Tinta Amarela, Tinta Roriz, Touriga Franca, Touriga Nacional, Sousão, and Tinto Cão make this Port just right after a big meal: sweet and rich, but not overpowering.
