The invention relates to a production method of a Luzhou-
flavor liquor, belonging to the technical field of liquor
brewing. The technical problem to be solved is to provide the production method of the Luzhou-
flavor liquor, by which spent grains can be fermented sufficiently. The production method of the Luzhou-
flavor liquor comprises the following steps of: a, preparation of
caproic acid bacterial liquid; b, preparation of pit mud enriching bacterial liquid; c, preparation of pit mud functional
bacteria: mixing the
caproic acid bacterial liquid and the pit mud enriching bacterial liquid, inoculating the mixed bacterial liquid to a culture medium of the pit mud functional
bacteria to obtain the pit mud functional
bacteria, and
drying to obtain the dried pit mud functional bacteria; d, mixing the dried pit mud functional bacteria, flavor-producing
yeast, B type enzymatic matters and red
starter esterified
enzyme together to obtain a compound microbial enzymic preparation, wherein the ratio of the
dry weight of the dried pit mud functional bacteria to the weight of flavor-producing
yeast to the weight of the B type enzymatic matters to the weight of the red
starter esterified
enzyme is 1:(0.25-0.35):(1-2):(0.30-0.45); and e, adding the compound microbial enzymic preparation to spent grains when the spent grains are fermented in a cellar, fermenting, taking the spent grains out of the cellar,
steaming to finally obtain the Luzhou-flavor liquor, wherein the addition amount of the compound microbial enzymic preparation is 3-8% weight of the grains in the spent grains.
