- Once the coffee has been picked, processing must begin as
quickly as possible to prevent fruit spoilage.
- The Dry Method The freshly picked cherries are simply spread
out on huge surfaces to dry in the sun. In order to prevent the cherries from
spoiling, they are raked and turned throughout the day, then covered at night
or during the rain to prevent them from getting wet.
- The Wet Method removes the pulp from the coffee cherry after
harvesting so the bean is dried with only the parchment skin left on. First,
the freshly harvested cherries are passed through a pulping machine to separate
the skin and pulp from the bean.
- Then the beans are separated by weight as they pass through
water channels. The lighter beans float to the top, while the heavier ripe
beans sink to the bottom. They are passed through a series of rotating drums
which separate them by size.When fermentation is complete, the beans feel rough to the
touch. The beans are rinsed by going
through additional water channels and are ready for drying.
