Distillation method and combined ageing method of solid state brewed liquor

Abstract

The invention discloses a distillation method and a combined ageing method of solid state brewed liquor, and belongs to the field of liquor brewage. In order to overcome the defects of an existing ageing method, such as long ageing time and insufficient flavor after ageing, the invention provides the distillation method and the combined ageing method of the solid state brewed liquor. The method combines distillation ventilation treatment, enzyme treatment, heating temperature control, ultrasonic treatment and micro-oxygenation to promote association of molecules in the liquor and bump of molecular energy while accelerating generation of flavor substances, so as to promote ageing of the liquor. The ageing method can obviously shorten the ageing of liquor, and the total acid and total ester in the liquor reach the national standard; in addition, the method effectively reduces the content of harmful substances in the liquor, and is suitable for demands of large-scale industrialization. Accordingly, the invention has quite wide market prospects.

Description

technical field

[0001] The invention belongs to the field of liquor brewing, and relates to a distillation method for solid-state brewed liquor and a combined aging method thereof. Background technique

[0002] Solid liquor distillation adopts atmospheric distillation retort. The principle is to create a thermodynamically separated environment in the distillation retort. According to the different boiling points of the components in the fermented grains, the low boiling point components are evaporated and then condensed to separate them. Alcohol and aroma and taste components are extracted from it. The liquor obtained by this distillation process contains more impurities, is pungent, has strong alcohol irritation, and is mixed with bad taste and bitter taste. It needs a long storage and aging process to become mellow and soft. And white wine has the shortcoming of long storage time and slow turnover in the aging process of storage, and takes up a large number of workshops a...
