The invention discloses a preparation process of composite fruit wine. The process comprises the following steps: mixing, crushing and fermenting kiwifruits, peaches, food-grade vitamin C and potassium pyrosulfite, respectively fermenting the obtained juice and peel residues under a certain condition to obtain pre-fermentation liquor A and pre-fermentation liquor B, fermenting and clarifying the pre-fermentation liquor A and the pre-fermentation liquor B under a certain condition to obtain clarified fruit wine, uniformly mixing purified water, the prepared apple ferment and the clarified fruitwine, adjusting the alcohol content to 10-12 degrees by using the prepared distilled wine, and performing filling and sterilization to obtain the composite fruit wine. The composite fruit wine produced by the process effectively retains nutritional ingredients, so that a large amount of beneficial ingredients in the fruits such as vitamins, trace elements including zinc, iron, calcium and selenium, amino acids, proteins and pectin are not easy to get lost. The fruit wine is good in taste, pure in chroma, clear and transparent, combines the nutrients of kiwifruits, peaches, apples, peach blossoms and brown sugar, has a unique flavor and strong fruit fragrance, and is particularly suitable for women to drink.
