Method for bottom microculture of fermentation pit for highly flavored type Baijiu

Abstract

The invention discloses a method for bottom microculture of a fermentation pit for highly flavored type Baijiu. The method is characterized by comprising the following steps: first, clearing the bottom of the fermentation pit; then uniformly turning over mud in the bottom of the pit with an iron fork; then sprinkling medium-high-temperature koji and cold boiled water to the bottom of the pit, and screeding after standing; uniformly sprinkling yeast powder to the surface of the bottom of the fermentation pit before fermented grains enter the pit, thereby finishing bottom microculture. The method disclosed by the invention is simple and convenient to operate; the mud in the bottom of the pit is subjected to nutritional supplementation on the basis of keeping original mud in the bottom of the pit, such that the activity of the mud and the quality of base Baijiu are improved.

Description

technical field [0001] The invention relates to a method for small cultivation at the bottom of a Luzhou-flavor liquor cellar. Background technique [0002] In the production of Luzhou-flavor liquor, pit mud is the foundation, Daqu is the driving force, and technology is the key. Pit mud is the base camp of microorganisms such as ester-producing aroma and acid-producing flavors. The quality of pit mud directly affects the quality of wine. Therefore, to make high-quality Luzhou-flavored wine, the quality of pit mud must first be grasped. The pit mud at the bottom of the cellar is the most important factor affecting the quality of the wine body. [0003] The pit mud at the bottom of the Luzhou-flavor liquor cellar contains the most abundant Clostridium, caproic acid bacteria, methane bacteria, butyric acid bacteria and other microorganisms that are conducive to the fermentation of wine grains, and are the main factors that produce various aroma substances in the wine body . ...
