Which grape variety is associated with wines that have high acidity and high tannin?

The grape variety that is widely recognized for producing wines with high acidity and high tannin is Nebbiolo. This variety is predominantly grown in the Piedmont region of Italy and is the main grape used in prestigious wines such as Barolo and Barbaresco. Nebbiolo is characterized by its complex flavor profile, including notes of cherry, rose, tar, and earthy undertones, and it typically exhibits both high acidity and robust tannins. This combination allows the wines to age exceptionally well, developing greater complexity over time.

While Sangiovese, another Italian variety, can also have high acidity and moderate tannins, it does not generally achieve the same level of tannin structure as Nebbiolo. Barbera tends to have lower tannins and is known for its fresh acidity and fruit-forward profile. Corvina, primarily used in Valpolicella wines, contributes to a blend but is not typically highlighted for high acidity and tannin in comparison to Nebbiolo.
