The invention relates to a preparation method for producing calcic fruit ice wine by adopting a fermentation process technology. The calcic fruit ice wine is prepared by the following steps of selection, cleaning, crushing, enzymolysis, juicing, freezing concentration of juice, inoculation, fermentation, wine pouring, gluing, filtration, ageing, blending, cold treatment, filtration, refining filtration, storage, sterilization, filtration and filling, wherein the step of freezing concentration of juice adopts a freezing concentration method to control the sugar content of the juice, determines sub-zero temperature according to the sugar content of the juice, removes ice after the juice is iced, and continues freezing till the sugar content reaches 180 to 220g/L. The preparation method uses the freezing concentration technology of juice to carry out 100% of raw juice fermentation, thus improving the typicality of the calcic fruit ice wine. By test, the preparation method determines the proper techniques for fermentation and gluing, does not add alcohol, pigment and preservative, highlights the characteristics of rich nutrition and elegant fruit flavor of fermented fruit wine, leads the fruit flavor and wine flavor to be harmonious in the calcic fruit ice wine, and leads the wine body to be complete, thus improving the cleanliness of wine and solving the problem that a finished fruit wine easily generates secondary sedimentation.
