This DOCG wine from Tuscany is a complex subject because there are no less than seven subzones:
- Colli Aretini
- Colli Fiorentini
- Colline Pisane
- Colli Senesi
Within these subzones the rules may vary but there will never be less than 70% Sangiovese with additional permitted grapes that may include Cabernet Franc and Cabernet Sauvignon.
