From harvesting to becoming green beans that can be stored long-term, coffee cherries must undergo processing. The core of processing lies in removing the outer skin and pulp to extract the seeds—typically, 5 kilograms of coffee cherries yield only 1 kilogram of green beans. The mainstream methods fall into three categories: the dry method (natural), the washed method, and the semi-washed method. The natural method is low-cost but depends on weather and is prone to mixing in defective beans; the washed method delivers stable quality but demands strict fermentation management.
