What are the aging potential and characteristics of Portuguese red wines?

Portuguese red wines’ tasting notes reveal the traits from their grape variety and origin, so their flavor appetizes from the differences provided in the region. Touriga Nacional wines are characterized by a deep, rich fruity flavor, including plenty of native harsh tannins. This type of wine is ageing-oriented. However, darker grapes such as Castelão are aged year by year in order to achieve flow of flavors and depth, which is exhibited when having them young and fruits together. The Douro and Dao regions are creating reds that can make it to the finish line because of their layers of flavors and age-worthiness; while others are early-drinking to have us pleased by them now.
