Concentrated fragrance type distilled spirit pit mud pit-maintaining liquid, production method thereof and concentrated fragrance type distilled spirit pit mud maintenance method

Abstract

The invention relates to concentrated fragrance type distilled spirit pit mud pit-maintaining liquid, a production method thereof and a concentrated fragrance type distilled spirit pit mud maintenance method, and belongs to the technical field of distilled spirit making. The production method of the concentrated fragrance type distilled spirit pit mud pit-maintaining liquid comprises the following steps of: a, uniformly mixing 25 to 40 parts of yellow water, 40 to 50 parts of tail water and 10 to 20 parts of squeezed liquor by weight to obtain mixed solution, wherein the squeezed liquor is liquid obtained by dehydration squeezing after wine lees are steamed; b, adding a high-temperature starter which accounts for 4 to 6 percent of the weight of the mixed solution and concentrated fragrance type distilled spirit pit-closing mud or pit mud which accounts for 3 to 5 percent of the weight of the mixed solution into the mixed solution, and uniformly mixing; c, fermenting at 25 to 35 DEG C for 3 to 7 days in an airtight way; and d, ending the fermentation, filtering to obtain the concentrated fragrance type distilled spirit pit mud pit-maintaining liquid.

Description

technical field [0001] The invention relates to a cellar mud culture liquid for Luzhou-flavor liquor and a production method thereof, and a maintenance method for pit mud of Luzhou-flavor liquor, belonging to the technical field of brewing. Background technique [0002] In the production of Luzhou-flavor liquor, in order to maintain and continuously improve the activity of microorganisms in the pit mud, it is necessary to add nutrient solution to promote the growth and reproduction of microorganisms in the pit mud. The cellar liquid maintains the cellar mud, one is to supplement the water for the pit mud; the second is to provide a richer microbial flora for the pit mud; the third is to provide a large amount of organic acids and esters for the pit mud to provide nutrients for the functional microorganisms of the pit mud , so that the pit mud soil forms a good soil aggregate structure, which is conducive to the good growth and reproduction of soil microorganisms, and makes t...

AI Technical Summary

Problems solved by technology

However, whether it is to use yellow water to raise cellars or to use tail water to raise cellars, there are certain defects.

Yellow water is used for cellar cultivation. Due to the low pH value and high acidity of yellow water, it is not conducive to long-term use. Long-term use will adversely affect the functional microorganisms of the pit mud.

Using tail water for cellar cultivation, the content of organic matter in tail water is not as good as that of yellow water, and it will also have adverse effects on the functional microorganisms of pit mud
