What is the minimum percentage of Sangiovese that DOCG Vino Nobile di Montalcino wines must contain?

Vino Nobile di Montalcino, recognized as a prestigious DOCG (Denominazione di Origine Controllata e Garantita) wine from Tuscany, mandates that a minimum of 70% Sangiovese be used in its blend. This requirement is significant because Sangiovese is the primary grape that defines the character and style of these wines, known for their elegance, complexity, and aging potential.

The legal requirement ensures that each bottle of Vino Nobile di Montalcino will consistently reflect the distinctive traits attributed to Sangiovese, including its flavors of cherry, plum, and earthy notes, alongside a certain tannic structure and acidity which can contribute to the wine's ability to age well. By specifying a minimum percentage, it also protects the authenticity and reputation of the wine, ensuring that consumers can trust the quality and true representation of the region.
