Functional pit mud for strong-flavor spirit, and manufacturing method thereof

Abstract

The invention discloses a functional pit mud for strong-flavor spirit. The pit mud comprises raw materials of, by weight: 70% to 75% of yellow mud, 12% to 14% of lotus pond mud, 1.2% to 1.5% of strong-flavor Daqu powder, 1% to 2% of bean cake powder, 0.05% of potassium dihydrogen phosphate, 0.8% of sodium acetate, 0.01% of magnesium sulfate, 4% to 5% of feints, and 5% to 6% of a functional bacilli liquid. The functional bacilli liquid is a mixed liquid of acetic bacilli, propionic bacilli and saccharomyces cerevisiae. The manufacturing method comprises steps of raw material preparating, mud mixing and in-pit cultivating. The functional pit mud for strong-flavor spirit provided by the present invention fundamentally prevents the pit from retrogression, and provides a good living environment for the microbes in the pit. With the functional pit mud, the flavoring components ethyl caproate and ethyl propanoate of the base spirit of the strong-flavor spirit can be increased, and the quality of the base spirit is improved.

Description

technical field [0001] The invention relates to a special-flavor wine functional cellar mud which can quickly stabilize the fermentation environment of a cellar and improve the quality of the special-flavor base wine and a preparation method thereof. Background technique [0002] Pit mud is the root of improving the quality of liquor. As a carrier of functional microorganisms, the pit mud adsorbs a large number of microorganisms. Under the joint action of various microorganisms, the base wine produces a variety of aroma components. However, the traditional pit mud cultivation is based on experience, which is extremely poor in science. Therefore, it can only rely on the pit mud to naturally and slowly generate beneficial microorganisms under the environment of long-term contact with the mother's grains, so as to achieve the so-called "old ripening". ". In recent years, all major and medium-sized wineries have devoted themselves to the research of artificial pit mud cultivat...
