Overview

Touriga Nacional is Portugal’s most prestigious red grape variety—a small-berried, thick-skinned grape that produces wines of extraordinary aromatic intensity, color depth, and concentration. Considered the finest variety for Port production and increasingly acclaimed for table wines, Touriga Nacional offers floral aromatics (violets, roses) combined with dark fruit intensity and remarkable structure. For enologists, Touriga Nacional represents an important study in low-yield, high-quality viticulture and the production of concentrated wines from small-berried varieties.
