Considered to be the finest of the grapes that are used to create the substantial and long-lived fortified wines known as Port. Touriga Nacional has a thick skin and small clusters of berries which help to contribute to the colorful and tannic wine it creates. In addition to the flowers, tannins and extract the Touriga Nacional brings to the Port table, the grape is an integral part of the blends of still red wine found in both the Duoro and Dão valleys, producing wines that are heavy in both red fruits and structure. Yields are low, but recent clonal selection has improved production.
While some of the best and most expensive wines of the Duoro and the Dão contain high percentages of Touriga Nacional, usually even the every day reds have at least a small portion of this varietal. Used for port production in Australia (where it is known as Touriga) as well as in small amounts in Chile, Argentina and the United States.
