The invention relates to a method for producing persimmon vinegar. The method is characterized by comprising the following steps: (1) cleaning persimmons, peeling, enucleating, and pulping the persimmons so as to prepare persimmon jam; (2) adding water, of which the volume is equal to that of
rice flour prepared in advance, into the
rice flour, moistening for 1h, then, adding rice
bran, mixing uniformly,
steaming for 1h, and stewing for 30-40 minutes; (3) taking out cooked materials, cooling to the temperature of 40 DEG C, and mixing with the persimmon jam and moldy
bran; (4) blending to cool to the temperature of about 28 DEG C, introducing barm, putting into a
fermentation tank, flattening and compacting fermented grains, sealing a tank opening with plastic cloth, and carrying out
starch saccharification and alcoholic
fermentation; (5) fermenting for about 3-5 days, blending raw
bran and a vinegar mother into mature fermented grains, mixing uniformly, and then, carrying out
acetic acid fermentation; (6) fermenting for 3-4 days, overturning the fermented grains, stacking until the fermented grains are mature, and then, flattening and compacting the fermented grains; (7) when the temperature of the fermented grains is reduced to
room temperature, sealing with plastic cloth, and covering the plastic cloth with common salt by the thickness of 3-5cm; (8)
ageing for one month, and then, carrying out vinegar drenching, sterilizing and clarifying, thereby obtaining a finished product vinegar.
