The invention discloses cherry Maotai-flavor Baijiu and a preparation method thereof. The preparation method comprises the following steps: preparing materials: based on mass percent, weighing 85 percent to 90 percent of sorghum and 10 percent to 15 percent of wheat as raw materials; based on mass percent, weighing 18 percent to 22 percent of rhizopus oryzae bran koji, 45 percent to 50 percent of aroma-producing yeast and 30 percent to 35 percent of lactic acid bacteria bran koji as auxiliary materials; weighing cherries which account for 3 percent to 7 percent of the mass of the sorghum for later use; after moistening the materials, steaming the materials under the pressure of 0.4MPa to 0.5MPa; after spreading and cooling the cooked materials, uniformly mixing the materials with a cherry mixture; after uniformly mixing with the auxiliary materials, accumulating and fermenting; putting the materials into a cellar and distilling to obtain the cherry Maotai-flavor Baijiu.
