A sweet hot beverage available from the replicators of Deep Space 9, ordered so often by Doctor Julian Bashir that it became as much his signature as raktajino was for the rest of the station.
Tarkalean tea is a hot drink served at the Replimat and at Quark's on Deep Space 9. It is closely associated with Doctor Julian Bashir, who usually asks for it extra sweet.
Bashir drinks it during his regular lunches with the Cardassian tailor Garak, among them the meal that opens the episode Cardassians, and it turns up at his table throughout the series. The name suggests an origin among the Tarkaleans, a people mentioned in several Star Trek series, although the tea itself is never explained on screen.
The drink is one of a handful of small habits, alongside Earl Grey for Picard and black coffee for Janeway, that the franchise uses to give its officers a domestic side.
