Abstract
The invention relates to a method for aging yellow wine with microaerobes, belonging to the technical field of biological engineering. In the invention, the aging of the yellow wine is accelerated manually and physically, which is a method for accelerating aging with microaerobes. The method comprises the following steps: after sterilizing the raw yellow wine, carrying out microaerobe treatment on the yellow wine by using specific ventilatory capacity and ventilation frequency, and periodically detecting primary physicochemical properties, amino acids, flavor substances, organoleptic properties and other indexes of the stored yellow wine. The yellow wine subjected to microaerobe treatment can implement aging, and achieves the aging standard in the aspects of color, scent and flavor, so that the yellow wine subjected to microaerobe treatment is identical to that naturally aged in a pottery jar. After being subjected to microaerobe treatment, the yellow wine aged for fewer years tends to the yellow wine aged for more years. The method for aging yellow wine can implement aging of the yellow wine instead of the traditional pottery jar for storing wine. The method has the advantage of outstanding aging effect. When the yellow wine industry adopts a large-scale container for storing wine, the method can reduce the volatilization loss of wine, shorten the storage period, enhance the production efficiency, reduce the occupied area and enhance the sanitary safety, thereby having high application value.
Description
technical field [0001] The invention relates to conditions affecting the aging of rice wine, which belongs to a method for artificially and physically accelerating the aging of rice wine, and belongs to the technical field of bioengineering. Background technique [0002] Usually, the taste of newly brewed rice wine is relatively rough, with insufficient smell, more irritating, and less soft. However, aging can effectively promote the association between alcohol molecules, alcohol molecules and water molecules, and promote the esterification of alcohol and acid. Make the wine fragrant and fragrant, taste sweet and soft. Therefore, rice wine usually needs to be stored and aged for at least one year before it can be sold. To obtain high-quality rice wine, it needs to be aged for a longer period of time, so that the unique mellow aroma of rice wine is more intense, more delicate, the wine quality is more coordinated, and the taste is more comfortable. . [0003] Both productio...
