A Complete Guide to Green Coffee Processing: Washed, Natural, and Honey Processing Methods and Their Flavor Differences

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.
