In 1996, Mugello’s sweet chestnut was granted the prestigious PGI (Protected Geographic Indication) status by the European Community. This recognition safeguards and guarantees the chemical-physical properties of agricultural products and food produced in specific geographic areas. IGP certification requires producers to adhere to a strict set of production rules; the produce is inspected by certified experts who must verify that the entire production stream conforms to approved regulations.
