Well see. You want to climb up to the peak of a high mountain and pick the red berries off this bush. Then you load sacks of them onto a donkey and haul them back down the hill. Ok, now don't eat them! You're going to spread them out all over the ground and let them dry up a little. Nope, still don't eat them. Now you're going to put them into a basket and shake them like crazy until all the parts you thought you were going to eat fall off. Now spread the seeds back on the ground and let them dry out more. Nope, don't plant them. Make a fire and put them in a pot hanging over the fire and start stirring. Keep stirring until they start to change colour and sound like a bunch of exploding maggots. Yes, I know they smell burnt and nasty, just trust me. Then take them off the heat and fan them with a big palm frond to cool them and wave away the skins. They smell better now, right? No! Still don't eat them. When you're going to do is take a handful and smash them up with a rock. Now, put that into a clean loin cloth suspended over a mug. Now pour boiling water over it. No, seriously. There you go coffee!
Oh, it tastes like burnt sandal leather? Well, dump some sugar and cream in it. Maybe a little vanilla and ice and drink it with a straw. There! Now it tastes nothing like coffee! Enjoy!
