Quint-berry juice was a very sweet juice made from quint-berry fruit.
On the Jedi mission to Romin in 24 BBY, Master Obi-Wan Kenobi sipped the super-saccharine beverage at an extravagant reception for the world's wealthy, hosted by Romin's corrupt tyrant-ruler, "Great Leader" Roy Teda. By awkward chance, Kenobi also met, then shared the same sweet drink with the criminal he was meant to be impersonating while on the planet.
