Tarine tea was a beverage, a variety of tea, created by steeping tarine leaves. It could be served either hot or cold, and was available on various locations including the planets of Batuu and Christophsis, as well as the moon of Jedha.
Specifically, tarine tea was a kind of tea prepared using tarine leaves that grew on tarine bushes. It was versatile and could be enjoyed either as a warm drink or a cold one. At Oga's Cantina, which was located in Batuu's Black Spire Outpost, the tea was served as a chilled refreshment. A combination of tarine tea and porridge made for a satisfying and hearty breakfast.
During the Battle of Christophsis, which took place in 22 BBY, the initial year of the Clone Wars, Jedi General Obi-Wan Kenobi of the Galactic Republic engaged in a meeting with General Whorm Loathsom of the Separatists, ostensibly to surrender. However, this was a ruse to allow Kenobi's former Padawan, Anakin Skywalker, along with Skywalker's new Padawan, Ahsoka Tano, to infiltrate the droid army's defenses and deactivate their deflector shield generator. Throughout these deceptive yet courteous negotiations, Kenobi asked for some refreshments and was given a cup of tarine tea, which he deliberately savored to further delay Loathsom. Ultimately, the Republic emerged victorious on Christophsis.
Holshef, an aging human man concealing himself from the Galactic Empire, would occasionally offer Merei Spanjaf tarine tea when she visited him to gather his credits for Yahenna Laxo, who was protecting him. Although some individuals enjoyed tarine tea, Baze Malbus from the Holy City on Jedha found its taste unpleasant. Resistance spy Vi Moradi was another person who disliked the flavor of tarine tea, but she kept this information from Archex to avoid hurting his feelings. Archex himself was not fond of tea either, but he had collected leaves to dry and explained their purpose to Moradi. Tarine tea was the preferred drink of General Armitage Hux, and it was also rumored to be a favorite among others within the First Order.
In the real world, a non-alcoholic version of this beverage can be found during breakfast at Oga's Cantina in Star Wars: Galaxy's Edge. The menu describes it as "Gold Peak Unsweetened Tea, peach, huckleberry, mint."
