Soil-brick combined yeast wine cellar and construction method thereof

Abstract

The invention relates to yeast wine fermentation, in particular to a soil-brick combined yeast wine cellar and a construction method thereof in the field of strong aromatic yeast wines. The yeast wine cellar of which not only the cellar moisture retention is good but also a wall body cannot collapse easily is provided by a method comprising the following steps of: culturing artificial aging cellar mud; building a two-component soil waterproof layer at the bottom of the cellar; ramming a two-component soil internal wall based on the waterproof layer at the bottom of the cellar; and building an inclining brick wall with a certain inclination angle by using red bricks on two sides next to the two-component soil internal wall respectively. The soil-brick combined yeast wine cellar overcomes the defects in the prior art, and can effectively improve the activity of cellar mud functional bacteria and accelerate the aging of artificially cultured cellar mud to ensure that the fragrance of a produced base liquor is a composite fragrance mainly comprising ethyl caproate, and the liquor body style is a typical concentrated fragrance type liquor style with 'a strong cellar fragrance, a sweet and clear taste, harmonious fragrances and long aftertastes'.

Description

technical field [0001] The invention relates to the fermentation of koji wine, in particular to an earth-brick combined koji wine cellar and a construction method in the field of Luzhou-flavor koji wine. Background technique: [0002] The production of Luzhou-flavor Daqu is different from other flavors in that pit mud and Wannian grains are used. "Old cellar produces good wine". The foundation of the pit, it needs to infiltrate the pit mud with the long-term continuous fermentation products to achieve the purpose of "nourishing the pit with the bad, and nourishing the bad with the pit", and gradually enrich the functional bacteria related to the aroma in the pit mud. [0003] As the only carrier of pit mud, the pit wall directly affects the moisture of pit mud: one of the main reasons affecting the biological activity of pit mud functional bacteria is the low water content of pit mud: it is an important growth factor and reproduction requirement of pit mud microorganisms If...

AI Technical Summary

Problems solved by technology

Its advantage is that the cellar pool has good water retention, which is beneficial to the growth of microorganisms in the cellar mud and the aging of the cellar mud; its disadvantage is that the water in the cellar mud slowly penetrates into the wall, which gradually increases the water in the wall, resulting in the cellar wall Collapsed, and when the cellar was rebuilt, it became a new cellar and lost the meaning of the old cellar

[0006] Brick cellar: with masonry as the main body, it is built into a wall shape, bamboo sticks are used, and cellar mud is applied. It is called a brick cellar. It has the advantages of stable structure and is not easy to collapse; the disadvantage is that the walls of the cellar are straight up and down, and the fermentation process produced It is not easy for things to enter the pit mud, and the purpose of "raising the cellar with the bad and raising the bad with the cellar" is not achieved. At the same time, the cellars penetrate each other, and the fermented grains that have just entered the pool are easily soaked by the fermentation product (yellow water), which makes the fermentation unusual
