The beverages are not pre-made. Like most of the food that goes up to the space station it is all dehydrated so that you are launching as little water as possible (and therefore additional mass). Water is recycled on the station as much as they can. So they have two methods for making coffee (that I am aware of): 1. Packets filled with essentially instant coffee that they add hot water to: https://www.youtube.com/watch?v=PvIT3l9QYnQ https://www.youtube.com/watch?v=PvIT3l9QYnQ 2. An espresso machine similar to a pod-based system. Fairly like an espresso machine on Earth since it relies on pressure. https://www.npr.org/sections/thesalt/2014/07/08/328130351/what-it-takes-to-make-a-decent-cup-of-coffee-in-space https://www.npr.org/sections/thesalt/2014/07/08/328130351/wh...
