Dão DOC

Overview

Dão stands as Portugal’s most elegant wine region, producing refined red wines from Touriga Nacional and other indigenous varieties that offer a marked contrast to the power of Douro and Alentejo. Protected by surrounding mountain ranges that create a unique microclimate, the region’s granite soils and continental altitude (up to 800 meters) produce wines of remarkable freshness, finesse, and age-worthiness. The recent focus on Encruzado has revealed Portugal’s greatest white wine variety. For enologists, Dão offers essential study in highland viticulture, Touriga Nacional elegance, and the expression of granite terroir.
