Method of Processing Green Coffee Beans

Abstract

A method of processing coffee berries which includes a fermentation process of bringing coffee berries having a coffee seed and coffee pulp into contact with microorganisms that metabolize said coffee pulp to cause fermentation, and a refining process. Green coffee beans are obtained by performing a fermentation process of bringing coffee berries, which have a coffee seed and coffee pulp, and microorganisms into contact with one another to cause fermentation, and a refining process.
