Which grape variety is primarily used in Chianti wines?

Chianti wines are primarily made from the Sangiovese grape variety, which is known for its high acidity and bright cherry flavors, along with herbal and earthy notes. Sangiovese is well-suited to the climate and terroir of the Chianti region in Tuscany, where it thrives and expresses the characteristics that define the wine. The grape's ability to convey the nuances of the soil and climate contributes significantly to the profile of Chianti wines, making it the foundational grape for this renowned Italian wine.

While other grape varieties like Canaiolo, Colorino, and even some international varieties can be blended into Chianti, Sangiovese is the dominant grape in the region's wine production, following regulations that dictate its minimum percentage in the blends. This ensures that the unique qualities of Sangiovese are at the forefront of any Chianti wine, making it synonymous with the region itself.
