Spiran caf was a specific type of caf that could be found across the expanse of the galaxy.
Back in 5 BBY, Kanan Jarrus, the Jedi survivor, and Hera Syndulla, the Twi'lek pilot, shared a cup of Spiran caf aboard the VCX-100 light freighter Ghost. They were traveling through hyperspace to the asteroid base known as Fort Anaxes. Jarrus was reminded of their time spent on the moons of Rion as he drank the caf with Syndulla.
In 34 ABY, Spiran caf was available at Oga's Cantina, which was located in Black Spire Outpost on the planet Batuu. This local caf variety was cultivated and roasted in the Batuuan mountains' foothills. Similar to other types of caf, it gave drinkers a boost of energy. At Oga's Cantina, it also contained alcohol and was served hot. Black Spire Brew, a richer variant, was served cold.
Spiran caf made its debut in the Star Wars Rebels episode titled "Out of Darkness," which was broadcast in 2014. Although the drink wasn't identified within the show, its name was later revealed in the trivia section for the episode on StarWars.com.
In the real world, it is one of the alcoholic drinks that patrons can purchase during breakfast hours at Oga's Cantina, situated in Star Wars: Galaxy's Edge. It was first unveiled as part of a large promotional event that took place on February 26, 2019, although certain media outlets mistakenly referred to it as "Spriran Caf." The menu describes it as "Peru Alto Mayo Organic Joffrey's Coffee, orange marmalade, Gosling's 151 rum, vanilla whipped cream, and citrus zest."
