Method for accelerating pit mud of strong aromatic liquor and spirits to age through old pit yellow water fermentation broth

Abstract

The invention discloses a method for accelerating the pit mud of strong aromatic liquor and spirits to age through old pit yellow water fermentation broth. The method comprises the following steps of:firstly, taking fresh yellow water in an old pit, evenly mixing the fresh yellow water in the old pit with water used for brewing at a certain ratio, and culturing under an anaerobic condition to obtain old pit yellow water fermentation broth; and taking the obtained old pit yellow water fermentation broth to independently improve the mud of a new pit, the mud of a degenerating pit and carry outcuring on the mud of a conventional pit. The method is simple, accurate and efficient, and provides different improvement ways according to circumstances by aiming at various situations. If the methodis adopted to carry out improvement or curing on the pit mud, pit mud aging can be more quickly realized (in 1-3 years).

Description

technical field [0001] The invention relates to a method for promoting the aging of Luzhou-flavor liquor cellar mud through the yellow water fermentation liquid of old cellar pools, and belongs to the technical field of wine making. Background technique [0002] Pit mud is an important material basis for the fermentation of Luzhou-flavor liquor, and the rich anaerobic bacteria in the pit mud play an important role in the formation of aroma substances in Luzhou-flavor liquor. The aging of the pit mud is essentially the aging of the pit mud flora, that is, as the fermentation time prolongs, the pit mud flora and the physical and chemical properties of the fermentation process adapt and interact with each other, gradually reaching the balance between the composition of the flora and the function of the flora. steady state. During the aging process of the cellar mud flora, most of the time is in the process of liquor fermentation except for the interval between fermentation row...

AI Technical Summary

Problems solved by technology

Current research on the composition of flora in new and old pit mud [1] It is confirmed that in the bottom mud of high-quality old pits, the eukaryotic flora has completely disappeared, that is, the eukaryotic flora is not conducive to the aging of pit mud

From another point of view, most of the eukaryotic flora are aerobic flora, while most of the old pit mud are anaerobic flora. The existence of aerobic flora proves that the anaerobic conditions of pit mud are not good, which is not conducive to anaerobic Bacteria, especially the growth of absolute anaerobic flora, is not conducive to the aging of pit mud, because methane bacteria are absolute anaerobic bacteria, and the existence of methane bacteria proves that the metabolic chain of pit mud flora is complete. If absolute anaerobic bacteria survive Not good, not only will not realize the aging of the pit mud, but will also hinder the integrity of the metabolic chain of the pit mud flora
