The best preparation would run like this: The coffee cherries are selectively picked as they ripen. The same day they are picked, the outer skin is removed, exposing the pulp. The pulp-covered beans are then subject to controlled fermentation in tanks. The ferment-loosened, flabby pulp is then gently washed off the beans and they are dried, after which the last layers of skin, now dry and crumbly, are stripped from the bean by machine.
