Arabica Gayo Coffee Bean, Speciality, Semi-Washed (Unroasted) Semi-washed Process (Pulped Natural Process) The semi-washed process, also known as the pulped natural process, combines elements of both the natural and washed processing methods. Ripe coffee cherries are pulped to remove the outer skin, but the beans are left covered in a thin layer of mucilage and dried without fermentation. This method results in coffees with a unique combination of fruity sweetness from the mucilage and clarity of flavor from the washed process, often exhibiting a creamy mouthfeel and nuanced acidity.
