Guojing dark-red organic pit mud and preparation method

Abstract

The invention relates to a Guojing dark-red organic pit mud and a preparation method, and belongs to the field of wine making methods. The organic pit mud consists of the following raw materials: yellow soil, red clay, yellow water, fermented grains, ending water, high-temperature daqu, bran and an angel aroma-producing yeast at the mass ratio of (80-90): (87-100): (14-16): (5-5.5): (3-3.5): (0.8-1): (0.7-0.8): (0.2-0.8). According to the organic pit mud provided by the invention, the raw materials are selected in accordance with the principle of 'reserving the materials from fermentation andapplying the materials to fermentation'; the flavor of the pit mud, which gets mature in fermentation, can be obviously improved under the condition that the number of such clostridia as caproic acidbacteria is guaranteed to be similar; and the fishy smell and mud odor of artificial pit mud are reduced, and the adverse influence of the fishy smell and the mud odor to the quality of base wine is relieved.

Description

technical field [0001] The invention relates to Guojing Chixuan organic cellar mud and a preparation method thereof, belonging to the field of wine making methods. Background technique [0002] The characteristic aroma component of Luzhou-flavor liquor is ethyl caproate, and its aroma is a compound aroma composed of ethyl caproate as the main body and other aroma components. The production principle of ethyl caproate in Luzhou-flavor liquor is: the esterase in Daqu plays an esterification role, and metabolizes the caproic acid produced by the caproic acid bacteria in the pit mud functional bacteria with the alcoholic yeast in the koji. The ethanol produced is biosynthesized into ethyl hexanoate. The main source of caproic acid bacteria is the pit mud on the four walls and bottom of the pit; the main source of alcoholic yeast is koji. The existing technical method for making artificial pit mud is cumbersome and requires a lot of raw materials. When the prepared pit mud is u...

AI Technical Summary

Problems solved by technology

The existing technical method for making artificial pit mud is cumbersome and requires a lot of raw materials. When the prepared pit mud is used in the production of raw wine, it will bring unpleasant fishy smell and muddy smell, which will affect the quality of raw wine. Activated carbon treats the above odors. The process is very troublesome and increases the cost of purification. At the same time, the discharge of a large amount of waste activated carbon has caused a certain purification pressure on the environment.
