Strong flavor type Baijiu pit mud curing liquid and preparation method thereof

Abstract

The invention discloses strong flavor type Baijiu pit mud curing liquid and a preparation method thereof. The strong flavor type Baijiu pit mud curing liquid is prepared from the following formula ingredients in parts by mass: 20 to 30 parts of ash calcium, 6 to 8 parts of edible alcohol, 1 to 2 parts of strains, 50 to 60 parts of yellow water, 5 to 7 parts of medium-high-temperature Daqu, 4 to 6 parts of yeast extracts, 1 to 2 parts of a humidizer, 6 to 10 parts of sodium hydroxide, 6 to 8 parts of fermented grains, 2 to 6 parts of methanobacterium culture solution and 60 to 100 parts of purified water. A high-quality aged pit mud is used as a bacterial strain source; the sterilization and culture conditions are simple; beneficial microbial strains such as caproic acid bacteria for brewing strong flavor type Baijiu are subjected to enlarging cultivation, so that the number and the effect of long-term domestication under the natural conditions can be achieved in short time.
