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. Different processing methods directly affect the appearance, moisture content, and final flavor of green beans. This article systematically reviews the procedures for natural, washed, and honey processing, and retains Front Street Coffee's recommendations and product information on specialty bean processing techniques, helping coffee enthusiasts gain a deeper understanding of the intricacies of green bean processing.
