The present invention relates to a method for preparing coffee wine by means of coffee cherries, the method comprising the steps of: (A) mashing coffee cherries including parchment and outer skin covering the parchment, and then adding water such that the solid matter is contained in 40 to 60 degrees Brix; (B) primarily fermenting the mashed coffee cherries by adding malt; (C) secondarily fermenting the primarily fermented coffee cherries by adding yeast; and (D) filtering the secondarily fermented coffee cherries to separate a filter residue and a filtered liquid. Therefore, coffee wine may be obtained from the filtered liquid, and fermented coffee beans may be obtained from the filter residue.
