Why doesn’t this exist?
Take dried beans, roast 'em, grind 'em, and brew some bean juice?
I have no idea if it would taste good or not, but we don’t know if we don’t try.
Edit: I need to see what dried beans I have and maybe go shopping. I will give this a try with a couple different types of beans and report back if I fart or not.
So going by OP’s analogy, we should make cherry juice out of all the varieties of cherries.
You can make cherry juice, but presumably you’d do that by crushing the cherry meat to extract the juice. That’s different from how coffee is made. To create cherry coffee, we’d have to take the cherry pits, dry them, roast them, grind them, then pour hot water over them.
