Abstract

The invention discloses a culture method and culture medium of a cellar mud bacterium liquid with special flavor-producing function. The culture medium comprises the following components in percentage by weight: 3-5% of waste fermented grains, 8-10% of high-quality cellar mud, 10% of bottom fermented grain immersion liquid, 0.2-0.5% of K2HPO4, 0.1-0.3% of NaAC, 0.005-0.01% of MgSO4, 2-4% of 95% alcohol and 5-10% of barium sulfide solution. The cellar mud bacterium liquid with special flavor-producing function, which is cultured by the culture medium, can provide a hexanoic acid bacteria / methane bacteria / nitrate reducing bacteria compound flora which takes effect on producing compound fragrance of a wine body, and solves the problem of lack of compound fragrance of the wine produced in thepresent cellar which serves for a short time.

Description

technical field [0001] The invention relates to the technical field of brewing, in particular to a method for cultivating special aroma-generating fungal liquid from pit mud and a culture medium thereof. Background technique [0002] In the Luzhou-flavor Daqu liquor, the complex aroma of the wine body is better compared with the wine produced in the cellar with a long use time compared with the cellar with a short use time. The main reason is that the caproic acid bacteria, methane bacteria and The number of nitrate-reducing bacteria is obviously more than that of the pit mud that has been used for a short time, and the effect on the production of complex aroma substances in the wine body is the joint action of caproic acid bacteria, methane bacteria and nitrate-reducing bacteria. We call this type of microorganism special organisms. Aroma function bacteria. However, there is no relevant research on how to artificially mix and cultivate the special aroma-generating function...
