The invention discloses rose-flavored wine and a preparation method thereof. The rose-flavored wine is prepared from wine and rose flowers; the rose flower, which is dried by microwave, is puffed and dried, and more importantly, enzyme deactivation and color fixation are achieved, so that the natural color of the rose flower is reserved to the greatest extent; by soaking and rehydrating in a water solution containing sericin peptide, the loss of active substances of the rose flower caused by freezing can be reduced to the greatest extent, the extraction rate of active ingredients of the rose flower can be improved, and meanwhile a solid foundation can be laid for subsequent variable temperature probiotic fermentation; through the organic combination of such low-temperature extraction technologies as high-pressure pulsed electric field, microwave, ultrasound, biological enzymolysis and the like, the functional substances and fragrance components of the rose flower can be reserved to the greatest extent; the obtained rose-flavored wine, which is catalyzed and aged by the combined action of the high-pressure pulsed electric field, ultrasonic technology and peracetic acid, is equivalent to the quality of existing normal fermented flavored wine which is aged for 8-10 years in quality index; and the rose-flavored wine, compared with the prior art, is good in aging effect, short in cycle and high in efficiency.
