PURPOSE: A method of extracting an enzyme from grains using microbes and a fermented enzyme beverage manufactured using thereof are provided to extract plant enzymes by fermenting grains with a complex strain and to manufacture a beverage which helps strengthen immunity and reduce body fat. CONSTITUTION: A method of extracting an enzyme from grains using microbes comprises the following steps: washing respectively the prepared grains and plants using a washing tub storing washing water(S110)； putting the washed grains and plants with a microbial complex strain in each fermentation tub for fermentation (S120)； extracting enzyme liquid from the each fermentation tub(S130)； putting the extracted enzyme liquid in a mixing tub for producing a mixture(S140)； putting the produced mixture in an aging tub for ripening the enzyme included in the mixture(S150)； storing the aged mixture in a storing tub(S160). The said prepared grains consist of white corvania containing nutritive components such as recithin, isoflavone, trypsin inhibitor and the like； whole oat containing water-soluble cellulose and dietary fiber； and rice bran helping rid of body waste and harmful metal. The said mixture consists of 40-60 wt% enzyme liquid of white corvania, 20-30 wt% enzyme liquid of whole oat, and 20-30 wt% enzyme liquid of rice bran. An additive is mixed together with the said mixture in order to add taste and flavor to the mixture. The additive is one of the mixtures consisting of xylitol and herb, xylose and herb, or glucose and herb at a ratio of 50 to 50. A fermented enzyme beverage consists of 92 wt%-97 wt% the mixture and 3 wt%-8 wt% the additive.
