In an effort to protect the authenticity of Buldan chestnuts, a unique variety from Denizli, producers have been granted a geographical indication certificate. This action was taken by the Buldan Chamber of Agriculture after Chinese chestnuts were falsely sold as Buldan chestnuts. The certificate, which verifies the distinct taste, aroma, and sugar content of Buldan chestnuts, has been given to farmers registered in the Farmer Registration System. This measure is anticipated to prevent financial losses for local farmers and maintain the authenticity of Buldan chestnuts in the market.
