““Why is coffee so valuable? isn't there other stuff in the, uh, multiverse, to find?"                 "Like what? Gold? There was enough gold and silver in the asteroid belt of your former solar system to make every house, car, building and road on Earth out of the stuff. Diamonds? shiny pebbles. Fiat currency? don't make me laugh. Utility is what creates value for the meta-traveler. Food, meta-vehicles, water, or at least whatever fluid solvent is necessary for continuing your biochemical reactions. Of these, the scarcest is good coffee. It rarely evolves, and only naturally evolved coffee has the right flavor. Only coffee grown in its native environment will please the palate. Few universes have the right cosmological constants and physical laws to even create good coffee. Good coffee only grows in narrow bands of subtropical climates and only at high elevations that aren't cold. Coffee is portable, dividable, consistent in mass, and quality can be tested with common olfactory senses. Every brew is a little different; the permutations of the coffee experience are endless. For most meta-traveling humanoid species, coffee is consistently satisfying. It is the only true currency."   *””
