The invention discloses fermented konjac aromatic vinegar and a production method thereof and belongs to the technical field of biological engineering. The konjac aromatic vinegar is prepared by the following steps: carrying out pre-treatment including squeezing, filtering, enzyme preparation treatment and the like on konjac to obtain clarified konjac fine powder; when fermenting and blending thekonjac fine powder, adding 80 to 85 parts of glutinous rice, 1 to 5 parts of the konjac fine powder, 10 to 15 parts of natural koji, 3 to 5 parts of pure culture koji, 120 to 150 parts of water, 5 to10 parts of saccharomyces cerevisiae, 135 to 145 parts of wheat bran, 5 to 8 parts of acetic acid bacteria, 75 to 80 parts of rice husks and 3 to 5 parts of table salt and fermenting to obtain the fermented konjac aromatic vinegar. The konjac health-care aromatic vinegar developed according to the technology has a fresh medicine aroma, a slight fermented medicine aroma, thick quality and abundantnutrients; the fermented konjac aromatic vinegar contains amino acids, protein, organic acids and the like of traditional aromatic vinegar, and also contains polysaccharide substances including oligo-glucomannan obtained by fermenting and decomposing the konjac fine powder and the like, so that the fermented konjac aromatic vinegar has abundant nutrients.
