Tulaberry wine is an alcoholic drink made from tulaberries that is made by the Karemma and the Dosi. In 2370, Grand Nagus Zek had Quark begin negotiations with the Dosi to purchase tulaberry wine. In reality, Zek cared little about the tulaberry sale, as the Ferengi leader was hoping the Dosi would reveal information about the Dominion. (DS9 episode: "Rules of Acquisition") The Ferengi later established a regular supply of tulaberry wine with the Karemma. (DS9 episode: "The Search, Part I") Quark also obtained tulaberry wine for his own profit. (DS9 episodes: "The Jem'Hadar", "Family Business")
