One of the most typical products of the Florence area is the sweet chestnut, especially the variety produced in the Mugello district. In 1996, Mugello’s sweet chestnut was granted the prestigious IGP (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. This means that monitoring begins in the chestnut woods and ends when the IGP Mugello sweet chestnut is packed and made ready for sale.
