Vine-coffee
From Wookieepedia, the Star Wars wiki.
Vine-coffee was a variety of coffee notoriously hard to rear.
Emperor Palpatine owned farms on various planets that provided the beans to produce high quality coffee and vine-coffee, solely for the use of his Court.
On Belsavis, the vine-coffee plant was grown on adjustable platforms built under the artificial dome of a volcanic rift valley - a plan conceived by Jedi Master Plett.
Like regular coffee, it could be prepared and dispensed from a coffee machine, and was usually served in a coffee cup.
Porcellus was known to serve the beverage in Jabba's Palace.
