Coffee cherries are the fruit of the coffee plant, and yes, you can make coffee from them! The process is fairly simple: first, the cherries are picked and then they're hulled (the outer fleshy part is removed). Next, the beans are roasted to desired darkness. Finally, the beans are ground up and brewed just like regular coffee.
The resulting coffee has a fruity flavor that is unlike any other coffee out there. If you're a fan of fruity coffees, then this is definitely worth trying!
