Embodiment 1

[0028] A production method for improving the flavor of rice-flavored liquor and promoting its aging, comprising the following steps:

[0029] Seal 100 tons of 23-degree rice wine in a stainless steel tank with heat-insulating material on the outer layer, add 80 kg of 20 angstrom activated carbon powder, and feed clean compressed air for 30 minutes at the same time; To 2 ℃, maintain 12h.

[0030] The temperature was lowered to 1°C by the refrigerating unit again, and at the same time, clean compressed air was introduced for 30 minutes, and the maintenance time was 48 hours.

[0031] Clean compressed air was passed again for 30 minutes, and the temperature was maintained at 1° C. for 5 days.

[0032] Use a diatomaceous earth filter to filter the liquor at 1°C until it becomes clear and translucent, then pass through clean compressed air for 30 minutes, and return the liquor to normal temperature, seal and age for 5 days to obtain the processed liquor.

Embodiment 2

[0034] A production method for improving the flavor of rice-flavored liquor and promoting its aging, comprising the following steps:

[0035] Seal 100 tons of 40-degree rice wine in a stainless steel tank with heat-insulating material on the outer layer, add 30 kg of 14 angm activated carbon powder, and feed clean compressed air for 40 minutes at the same time; To 4 ℃, maintain 12h.

[0036] The temperature was lowered to -2°C by the refrigerating unit again, and at the same time, clean compressed air was introduced for 45 minutes, and the maintenance time was 24 hours.

[0037] Clean compressed air was passed again for 40 minutes, and the temperature was maintained at -2°C for 4 days.

[0038] Use a diatomaceous earth filter to filter the wine at -2°C until it is clear and translucent, then pass it through clean compressed air for 45 minutes, and return the wine to normal temperature, seal and age for 7 days to obtain the processed wine.

Embodiment 3

[0040] A production method for improving the flavor of rice-flavored liquor and promoting its aging, comprising the following steps:

[0041] Seal 100 tons of 52-degree rice wine in a stainless steel tank with heat-insulating material on the outer layer, add 40 kg of 18 angstrom activated carbon powder, and feed clean compressed air for 45 minutes at the same time; To 3 ℃, maintain 12h.

[0042] The temperature was lowered to -8°C by the refrigerating unit again, and at the same time, clean compressed air was introduced for 40 minutes, and the maintenance time was 36 hours.

[0043] Clean compressed air was passed again for 45 minutes, and the temperature at -8°C was maintained for 2 days.

[0044] Use a diatomaceous earth filter to filter the wine at -8°C until it is clear and translucent, then pass in clean compressed air for 40 minutes, and return the wine to normal temperature, seal and age for 10 days to obtain the processed wine.

Abstract

The invention discloses a rice-flavored wine flavor improving and aging promoting method. The method includes steps: sealing to-be-treated rice wine in wine storage vats, adding activated carbon powder, feeding compressed air, cooling wine liquor to 2-4 DEG C, and keeping for 12h or longer; cooling wine liquor to a temperature ranging from -8 DEG C to 1 DEG C, feeding compressed air, and keeping for 24-48h at the temperature; feeding compressed air for 30-45 minutes, and keeping for 2-5 days at a temperature ranging from -8 DEG C to 1 DEG C; filtering the wine liquor through diatomite until the wine liquor is crystal clear; feeding compressed air into the wine liquor for the last time, and after the wine liquor recovers to the normal temperature, hermetically alcoholizing for 5-10 days toobtain aged rice wine. The method has advantages that by intermittent air feeding, oxidation of alcohol and aldehyde in wine is accelerated, and reactions of esterification, condensation, redox and the like are accelerated; in addition, volatile substances such as hydrogen sulfide, mercaptan and dimethylsulfide in wine liquor can be effectively eliminated, and wine aging is promoted.

Description

technical field [0001] The invention belongs to the field of liquor brewing, in particular to a method for improving the flavor of rice-flavored liquor and promoting its aging. Background technique [0002] Rice-flavored liquor, also known as honey-flavored liquor, or rice wine for short, is one of the four flavor types of traditional Chinese liquor. It has a history of thousands of years and can be said to be the earliest flavor type in China. However, at present, baijiu is increasingly neglected by the younger generation, and the inheritance of Chinese baijiu culture and history is in jeopardy, and rice-flavored baijiu is no exception. [0003] The freshly produced rice wine is mostly dry and pungent, with the taste of chaff and burnt bitterness. Generally, it takes 3 years of natural aging to complete the aging process of rice wine, showing the appearance of ethyl lactate, ethyl acetate and β- Honey aroma and smooth taste composed of phenylethyl alcohol. However, long-t...
