Embodiment 1

[0031] A kind of cellar mud for brewing wine, the formula of pit mud is shown in Table 1:

[0032] Table 1

[0033]

[0034] Among them, the foundation mud is the soil below 50cm of the ground surface. After removing the sundries, the soil is exposed to the sun until it is completely dry, crushed and filtered through a 100-mesh sieve to obtain the foundation mud. Daqu powder is obtained by pulverizing high-quality medium-high temperature Daqu stored for 6 to 12 months. The hot water is water with a temperature above 90°C, and the tail is a high-quality tail with an alcohol content of 20% vol, which is the component between the third stage of liquor extraction and the end of the alcohol component in the liquor distillation process. The yellow water is filtered through three layers of gauze, and after removing the residue, it is mixed with the first part of the tail.

Embodiment 2

[0036] The pit mud preparation process includes the following steps:

[0037] (1) Shovel the basic mud into the mixer and first scald the basic mud with hot water above 90°C and stir evenly;

[0038] (2) Melt the first part of Daqu powder and high-quality pit mud with warm water, add it to the basic mud in (1), mix evenly, spread it on the cement floor, and then mix in the yellow water and the first part of wine tail in proportion, heap.

[0039] (3) First sprinkle the second part of koji powder on the cement floor, transfer the mud piled up in 2) to the second part of koji powder, evenly sprinkle the second part of the wine tail, and then sprinkle the third part of koji powder on the mud On the surface, cover the soil with unextracted grains, covering a thickness of about 10cm, and finally cover the grains with a plastic film, and naturally pile up and ferment for 15 days to obtain the primary pit mud;

[0040] (4) Transfer the initial pit mud to an empty pit mud pit or a c...

Embodiment 3

[0045] The pit mud recipe is:

[0046] base mud old pit mud Daqu powder yellow water tail hot water 1000 copies 100 copies 50 copies 70 copies 110 copies 430 copies

[0047] This embodiment includes the following steps:

[0048] (1) Shovel the basic mud into the mixer and first scald the basic mud with hot water above 90°C and stir evenly;

[0049] (2) Melt Daqu powder and high-quality pit mud with warm water and add it to the basic mud in (1), mix evenly, spread it on the cement floor, then mix in yellow water and wine tails in proportion, and pile up.

[0050] (3) Cover the soil with the discarded grains that have not been taken out of the wine, covering about 10cm thick, and finally cover the grains with a plastic film, and naturally accumulate and ferment for 15 days to obtain the primary pit mud;

[0051] (5) Transfer the initial pit mud to an empty pit mud pit or a cellar pool for producing distilled wine, and then put it into the ...

Abstract

The invention discloses pit mud for making Baijiu and a preparation method thereof. The pit mud is prepared from the following ingredients in parts by weight: 950 to 1050 parts of basic mud, 95 to 105parts of high-quality pit mud, 52 to 65 parts of Daqu powder, 65 to 75 parts of yellow water, 100 to 115 parts of feints and 400 to 450 parts of hot water. The manufacturing method provided by the invention has the advantages that the required fermentation period is short; the operation is simple; each parameter can be easily controlled; the manufacturing can be completed in a workshop; and special equipment is not needed.

Description

technical field [0001] The invention relates to the field of wine making, in particular to a cellar mud for wine making and a preparation method thereof. Background technique [0002] The quality of the pit mud plays a vital role in the quality of Luzhou-flavor liquor, because the pit mud is rich in microorganisms and is an important source of microorganisms in the fermentation of wine grains. The most important thing is that the pit mud is rich in Caproic acid bacteria can carry out mass transfer through yellow water, which has an important impact on the main flavor of Luzhou-flavor liquor. Therefore, good pit mud can produce high-quality liquor, and high-quality pit mud is particularly important for improving enterprise profitability. The demand for high-quality pit mud in enterprises is gradually increasing. This makes the study of high-quality pit mud an unavoidable and important topic for liquor production enterprises and liquor researchers. [0003] At present, the m...
