The natural method implies that cherries are dried in the sun, instead, the washed or wet method requires that the freshly picked drupes are immersed in tanks of water: in this way ripe cherries are separated from the immature ones or that have defects. The latter, floating are so removed.

At this point, drupes are passed through machines that in a continuous flow of water break peel and pulp. As a result, the grains are still covered  by mucilage and endocarp. The latter, are then fermented in large tanks with or without water from 8 to 72 hours, in this way mucilage ferments and decomposes.

At the end of this stage, coffee beans are put in tanks or cement ducts and washed. At last, they are dried in the sun as in the natural method.

At this point the coffee is passed through machines that break the endocarp without damaging the beans.
