Touriga Nacional

From Wikipedia, the free encyclopedia

Touriga Nacional is a variety of wine grape used predominantly to make port, and considered by many to be Portugal's finest grape.

Also occasionally known as Mortágua, the Touriga Nacional grape is unpopular with some vineyards as its grapes are unusually small, leading to comparatively low yields. Nonetheless, it is hard to find a manufacturer of port that does not consider the grape as one of its most important ingredients, and it is the principal variety used in the great vintage ports and table wines of the Douro valley.

Recently its use in the production of dry table wines has increased, particularly in the Rio Dão region of Portugal.
