 "Mastic is also produced on the Çeşme peninsula, on the Turkish coast across the Aegean from Chios." 

 As far as I know this is not true. Some known tries failed. Mastic is produced only in the South part of Chios. Not even one gram of mastic is produced in the North part. I think that the only source of mastic for Çeşme is the contraband activities.
