The farmers use a wet method or known as a washed coffee process. The coffee cherries are sorted in the water. The unripe or bad cherries float to the surface and the ripe or good cherries will sink. The cherries are pressed through a machine and screen using water and this helps some of the skin and the pulp to be removed. The balance of the pulp and skin is removed during fermentation.
During fermentation and the wash method, the remainder of the pulp is removed by the breakdown of the cellulose and the addition of microbes, as well as washing the beans in water. Fermentation can be done with extra water or, in "Dry Fermentation", in the fruit's own juices only.
