Chestnut producers in Aydın's Nazilli district are defending their geographically marked Aydın chestnut against the Chinese chestnut, as they have received a geographical indication and EU registration. They are upset that Chinese chestnuts are being sold using the names Aydın chestnut and Nazilli chestnut, as they are known as horse chestnuts and are used as animal feed, lacking both taste and use for roasting or in making chestnut candy. Producers and the Nazilli Chamber of Agriculture are demanding that the origin of imported Chinese chestnuts be stated when sold, to prevent confusion with the geographically indicated Aydın chestnut.
