What is the main grape variety used in making Chianti wines?

Chianti wines are primarily made from the Sangiovese grape, which is iconic to the region and plays a central role in the character of these wines. Sangiovese is known for its bright acidity, firm tannins, and cherry-like flavors, which contribute to the overall profile of Chianti. The grape thrives in the terroir of Tuscany, where Chianti is produced, and its characteristics reflect the climate and soil of the area.

In addition to being the main grape, Sangiovese is often blended with other varietals to enhance the complexity and flavor profile of the final wine. However, regardless of these blends, Sangiovese must constitute a significant proportion of the wine to qualify as Chianti. This makes it not only the predominant grape but also the defining one, with its unique traits strongly influencing the style and quality of Chianti wines.
