Abstract: The invention provides a method of processing green coffee beans that improves the aromas and flavors of green coffee beans through simple means, allowing richly fragrant green coffee beans that have unique aromas to be obtained with ease. A method of processing green coffee beans includes a fermentation process by bringing green coffee beans, which are unground seeds from coffee berries, microorganisms, and nutritive substances that are metabolized by the microorganisms into contact with one another to cause fermentation, followed by a separation process of separating out only said green coffee beans that have passed through the fermentation process.

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.

Abstract: A method of treating coffee cherries, comprising a refining step for separating and refining green coffee beans from coffee cherries, wherein the coffee cherries are steam treated, after which the green coffee beans are separated and refined.

Abstract: A method for manufacturing a coffee beverage is provided that is capable of efficiently removing precipitating components and turbid components from a highly concentrated coffee extract 1, and that is also capable of addressing increases in the production volume of the coffee beverage without particularly large changes being made to the scale of the equipment. The coffee extract 1 obtained from an extraction process performed on ground roasted coffee beans is diluted in the method for manufacturing a coffee beverage, and the coffee extract 1 is filtered using a cross-flow filtering apparatus before dilution.
