Abstract： In this study， coffee pulp with peel was used as raw material to brew fruit wine， and the optimum brewing process of fruit wine was determined by single factor test. The results showed that the optimum pretreatment process parameters were as follows： pectinase addition 0.05%， enzymolysis temperature 40 ℃， enzymolysis time
4.0 h. The optimum fermentation process parameters were as follows： the addition amount of BV818 yeast was 0.50%， the initial sugar content was 23%， the fermentation temperature was 25 ℃， and the fermentation time was 6 d or 7 d.
Keywords： coffee pulp with skin; enzymatic hydrolysis; fermentation; fruit wine
