Problems solved by technology

However, the above filtering method is only applicable to foreign distilled liquor and not to oak barrel liquor. The reason is that no koji is used in the production of foreign distilled liquor, and the liquid fermentation of single bacteria results in almost pure alcohol, less flavor substances and weak aroma. , which is different from the rich flavor substances of Chinese liquor. Experiments show that diatomaceous earth filtration will seriously damage the flavor of oak barrel liquor

Abstract

The invention relates to a liquor production method, and particularly discloses an oak barrel liquor clarification method which comprises the step of performing membrane filtration on oak barrel liquor; wherein the barrier molecular weight of a filter membrane used in the membrane filtration step is 250,000-300,000 Daltons. The method has the advantages that the technical problem of turbidity of the liquor in an oak barrel after pulp addition and alcohol content reduction and during storage on the premise of keeping the original taste and color of the oak barrel liquor is solved. The method has the advantages that the filtering precision is high, the filtering flow is large, the color, flavor and taste of the oak barrel liquor are not damaged, the turbidity of the oak barrel liquor can beeffectively removed after the oak barrel liquor is filtered by a device, the oak barrel liquor is not turbid again after being frozen for 72 hours at the temperature of-10 DEG C, and the freezing resistance and low-temperature stability are effectively improved.

Description

technical field [0001] The invention relates to a wine production technology, in particular to a liquor production technology. Background technique [0002] Oak barrel liquor is a new type of improved liquor in recent years. It is obtained by storing the brewed original liquor in oak barrels and extracting the flavor components in the barrels. For example, publication number is that the patent document of CN105950420A promptly discloses a kind of method of improving wine quality with oak barrel storage liquor. Different from traditional liquor, oak barrel liquor has a golden and transparent amber color due to the extraction of tannins, polyphenols and other substances in oak. [0003] The same as the traditional liquor brewing technology, the newly brewed oak barrel liquor is usually not suitable for drinking due to its high alcohol content, and needs to be added to reduce the alcohol content to improve the taste of the wine. Experiments have shown that oak barrel liquor w...
