By adopting the method, Chinese wampee leaves and Chinese wampee fruits are mixed to make fermented wine for the first time, and the key problems of juice preparation, enzyme treatment, early-stage separated fermentation, later mixed fermentation, filtering and the like are mainly solved. High-temperature treatment is avoided in the whole process, so that on the basis that the quality of fermented wine is ensured, flavor substances and active components in the Chinese wampee leaves and the Chinese wampee fruits are not damaged. Wine residues are maintained in a fermentation system all the time, so that the faint scent of the Chinese wampee leaves, the fruit fregrnace of the Chinese wampee fruits and the special fragrance of fermented wine are generated; and meanwhile, antioxidation active substances in raw materials are maintained, and the fruit wine has the effects of invigorating the stomach and removing food retention, circulating qi and relieving pain, quenching cough and relieving asthma and the like.
