Quality-based liquor storage technology for baijiu

Abstract

The invention discloses a quality-based liquor storage technology for baijiu. The quality-based liquor storage technology for baijiu adopts layered and segmented liquor flowing and comprises steps as follows: (1), fermented grains subjected to diastatic fermentation are subjected to layered pulling out and are stacked, wherein the layered pulling out is executed according to the sequence of surface-layer fermented grains, upper-layer fermented grains, middle-layer fermented grains, lower-layer fermented grains and bottom-layer fermented grains or dual-wheel bottom fermented grains; (2), single grain powder or mixed grain powder accounting for 15%-25% of the mass of each layer of fermented grains is added to each layer of fermented grains in the step (1), the components are stirred and mixed uniformly, and mixed fermented grains are obtained; (3), the mixed fermented grains are put in a retort, atmospheric pressure is controlled in a range from 0.05 MPa to 0.07 MPa, and the steam pressure is regulated to be lower than or equal to 0.03 MPa after liquor flowing starts; each layer of fermented grains adopts segmented liquor storage. According to the technology, each layer of segmented liquor is separated and extracted, advantages of each layer of segmented liquor are shown as far as possible, the liquor after storage is suitable for blending of finished alcohol of all grades, and selection range of flavoring liquor is enlarged.

Description

technical field [0001] The invention belongs to the technical field of wine brewing, and in particular relates to a process for picking wine for quantity and quality of (robust-flavor) liquor. Background technique [0002] Various starch or sugar raw materials, under the action of saccharification, starter or separate starter, are fermented by microorganisms to produce wine, and then distilled to extract liquor. In the extraction process, "quantity and quality picking" is carried out according to the quality of liquor, which is a very important production link and process technology in liquor production. [0003] Patent No. CN201210426653.7 "A staged wine picking process for liquor production, which is a process for selecting high-quality wine in the process of liquor production. Step to determine the different qualities of the distilled wine and pick them separately. The good quality is processed into finished wine, and the bad one is used for other purposes." There are d...
