Technological method for brewing white spirit by single-pit circulation method

Abstract

The invention discloses a technological method for brewing white spirit by a single-pit circulation method, and belongs to the technical field of white spirit brewing. The technological method comprises the following steps of: 1) respectively weighing a single-grain spirit body raw material, a multi-grain spirit body raw material and auxiliary materials according to a ratio, and carrying out fine crushing and cooking treatment on the weighed raw materials; 2) when a pit is not opened at the end of a fermentation period, extracting yellow water through a pre-buried yellow water pipe, then opening the pit to take off sealing mud, taking out fermented grains subjected to saccharification fermentation from the pit in a layered manner, and stacking; 3) dividing the taken-out fermented grains in each layer into two groups, respectively adding the single-grain spirit body raw material and the multi-grain spirit body raw material, stirring and mixing uniformly, and scattering the auxiliary materials; and 4) taking out the fermented grains in each layer in a layered manner, distilling in a layered manner, and picking the spirit in a segmented manner. According to the technology, a single-grain type and a five-grain type are adopted for separate fermentation, and small-pit type fermentation is adopted, so that the brewed white spirit more fully integrates single-grain mellow and five-grain fragrant essence, and the spirit body is soft in taste and low in alcoholic intoxication degree, and has the style characteristics of strong pit fragrance, sweet and soft taste, harmonious fragrance, and soft, sweet and refreshing taste.

Description

technical field [0001] The invention belongs to the technical field of liquor brewing, and in particular relates to a single cellar circulation method for brewing liquor. Background technique [0002] The brewing of liquor has a long history in my country, and the basic principle and process of its brewing mostly follow the traditional way to produce. In traditional wine production, most of the winemaking enterprises with a certain scale adopt the method of cellar fermentation. The cellars used for production now mainly include the Tiaoshi cellar of "Moutai Liquor", the mud cellar of "Luzhou Laojiao", and the "Baiyun" cellar. The brick cellar of "Bian", the new mud cellar of "Xifeng Wine", etc. In the traditional wine production process, it is necessary to take out the fermented dregs from the cellar and steam the wine with brewing equipment. The traditional methods for removing the dregs include "original cellar method" and "running cellar method". [0003] The original c...

Problems solved by technology

[0006] The object of the present invention is to aim at the defects in the prior art, and provide a single-cellar circulation method for brewing liquor. The single-cellar circulation method is characterized by less opening of cellars, layering, and avoiding long-term exposure of the cellar pools. In the air, it solves the unfavorable factors of climate and environment such as dry climate and large evaporation in Hexi area that are unfavorable to wine making, significantly improves the yield and quality of semi-finished wine, and reduces production costs
