PURPOSE: A method of manufacturing functional fermented coffee using a fast-fermented bean paste is provided to manufacture fermented coffee which produces useful components for the human body and is softly fermented by the activity of various lactobacilli and organic acids.CONSTITUTION: A method of manufacturing functional fermented coffee using a fast-fermented bean paste comprises: washing beans with clean water, macerating the same in water for 24 hours, and removing water by placing the beans on a basket adding 3-4 times of drinking water based on the weight of the soaked beans and boiling the same at 113-115 deg. Celsius for 5-6 hours removing water by scooping the boiled beans with the basket and cooling the same to 40-45 deg. Celsius washing the peeled and dried raw coffee with clean water and macerating the same for 24 hours mixing the macerated coffee and the boiled bean at a weight ratio of 6:4 inoculating the mixed boiled beans and macerated coffee with a bacillus strain at a 800:2 weight ratio fermenting the inoculated mixed boiled beans and macerated beans in a fermentation room at 38-45 deg. Celsius for 24-36 hours separating coffee from the completed fermentation product, washing, and hot-air drying the same placing the dried coffee in a container and roasting the same rapidly cooling the fermented coffee at -20 deg. Celsius after roasting the same and manufacturing coffee bean powder and mixing the coffee bean powder in hot water, and manufacturing coffee by extracting, spraying, and freeze drying the coffee using various coffee extracting machines including a filter.COPYRIGHT KIPO 2013본 발명은 야생 사향고양이나 태국에서 사육되는 코끼리가 커피열매를 따 먹거나 인위적으로 먹여 커피가 사향고양이나 코끼리 체내 소화기관을 통과하여 소화가 안 되고 배설한 커피는 그 맛과 향이 독특하고 귀해서 고가에 거래되고 있음을 상기하여 사향고양이나 코끼리 체내 소화기관 환경과 비슷한 환경을 인위적으로 만들고자 그 방법으로 청국장 발효과정의 환경이 사향고양이 소화기관을 통과하는 커피의 환경이 비슷하기 때문에 삶은 콩과 생 커피를 섞어 바실러스균주를 접종시켜 커피를 발효시키면 바실러스균의 작용에 의해서 다량의 유산균과 각종 유기산의 생성 및 작용으로 부드럽게 발효되고 커피와 콩에 없었던 인체에 유용한 성분들이 생성되기 때문에 커피의 맛과 향이 사향고
