The Touriga Nacional originally comes from the Dão, in the heart of Portugal. There is a village there named Tourigo. But it became famous in the Douro Valley, where port wine is produced. When the five best varieties were selected from the motley assortment of grapes growing in the vine terraces in the 1980s, the Touriga Nacional was the first choice. It smells of cassis, raspberry, plum, violet and liquorice, and is concentrated on the palate with supple tannins. It does well not only in port wine, but also in dry reds. Solo, the Touriga Nacional tastes almost too intense; therefore, it is usually blended with other varieties such as Touriga Franca and Tinta Barroca. Developed in barriques, the wines show their full potential. In the past ten years, the cultivation area of this grape has more than doubled, and spread to the whole of Portugal.
