Embodiment 1

[0025] A method for cultivating multi-grain Luzhou-flavor liquor in an artificial cellar mud, specifically comprising the following steps:

[0026] Step S1: take the yellow mud and dry it, crush it through a 100-mesh sieve, then add the first mixed solution and mix evenly to obtain a yellow mud ball, so that the water content of the yellow mud ball is 48wt%;

[0027] Step S2: Take the pit skin mud, add the second mixed solution and mix evenly to prepare pit skin mud balls, so that the water content of the pit skin mud balls is 48wt%;

[0028] Step S3: Mix the yellow mud ball prepared in step S1 and the pit skin mud ball prepared in step S2 in a weight ratio of 2:1, then add activated carbon fibers of 1% of the total weight of the yellow mud ball and pit skin mud ball, and mix After uniformity, the basic mud mass is obtained;

[0029] Step S4: Take high-quality pit mud, add wine tail, yellow water and distiller's grain squeeze liquid and mix evenly to prepare high-quality pit ...

Embodiment 2

[0042] A method for cultivating multi-grain Luzhou-flavor liquor in an artificial cellar mud, specifically comprising the following steps:

[0043] Step S1: take the yellow mud and dry it, crush it through a 100-mesh sieve, then add the first mixed solution and mix evenly to obtain a yellow mud ball, so that the water content of the yellow mud ball is 50 wt%;

[0044] Step S2: Take pit skin mud, add the second mixed liquid and mix evenly to prepare pit skin mud balls, so that the water content of pit skin mud balls is 50wt%;

[0045] Step S3: Mix the yellow mud ball prepared in step S1 and the pit skin mud ball prepared in step S2 uniformly in a weight ratio of 3:1, then add activated carbon fibers of 1% of the total weight of the yellow mud ball and pit skin mud ball, and mix After uniformity, the basic mud mass is obtained;

[0046] Step S4: Take high-quality pit mud, add wine tail, yellow water and distiller's grain squeeze liquid and mix evenly to prepare high-quality pit...

Embodiment 3

[0059] A method for cultivating multi-grain Luzhou-flavor liquor in an artificial cellar mud, specifically comprising the following steps:

[0060] Step S1: take the yellow mud and dry it, crush it through a 100-mesh sieve, then add the first mixed solution and mix it evenly to obtain a yellow mud ball, so that the water content of the yellow mud ball is 55wt%;

[0061] Step S2: Take the pit skin mud, add the second mixed solution and mix evenly to prepare pit skin mud balls, so that the water content of the pit skin mud balls is 55wt%;

[0062] Step S3: Mix the yellow mud ball prepared in step S1 and the pit skin mud ball prepared in step S2 evenly in a weight ratio of 5:1, then add activated carbon fibers of 1% of the total weight of the yellow mud ball and pit skin mud ball, and mix After uniformity, the basic mud mass is obtained;

Abstract

The invention discloses a method for culturing artificial pit mud of multi-grain Luzhou-flavor liquor. The method comprises the following steps of S1, preparing yellow mud pies; S2, preparing pit skinmud pies; S3, mixing and adding activated carbon fibers to prepare basic mud pies; S4, preparing high-quality pit mud pies; and S5, mixing the mud pies, adding a nutritional material and a fermentation promoter, and performing fermentation to prepare the artificial pit mud. The fermentation promoter is prepared by the following steps of A1, preparing aroma-producing yeast liquid; A2, preparing bacillus subtilis culture liquid; A3, preparing neutral protease activation liquid; and A4, taking soybean meal and bran as matrixes, carrying out mixed culture on aroma-producing yeast and bacillus subtilis, and performing drying to obtain the fermentation promoter. According to the invention, the problems that in the prior art, the quality of the artificial pit mud is poor, the variety and quantity of strains do not reach the standard, the culture time of the artificial pit mud is long, and the yield is low are solved.

Description

technical field [0001] The invention belongs to the technical field of brewing, and in particular relates to an artificial cellar mud cultivation method for multi-grain Luzhou-flavor liquor. Background technique [0002] Luzhou-flavor liquor occupies a dominant position in China's liquor market, and its excellent quality is closely related to pit mud. The quality of the pit mud directly affects the yield and quality of the base wine, and is also closely related to the style of the wine. Pit mud is the carrier and nutrient bank for microorganisms such as ester-producing aroma, acid-producing and flavor-producing microorganisms. Pit mud is an important factor affecting wine quality, because only pit mud can provide rich acid-producing and ester-producing microorganisms, such as propionic acid bacteria, caproic acid bacteria, and butyric acid bacteria. However, the traditional pit mud cultivation is all based on experience, which is extremely poor in science. Therefore, it ca...
