Abstract

The invention discloses a method for preparing brandy by extracting aroma substances. The method comprises the following steps: S1, preparing 79%vol of an alcoholic solution to serve as an extractionagent; S2, weighing five different types of oak chips such as mocha, vanilla, fruit, natural and Cognac, and wrapping by gauze; S3, mounting a soxhlet extractor, adding the extraction agent into a round-bottom flask, and adding one oak chip into the intermediate soxhlet reflux device; S4, turning on a heating jacket, extracting and refluxing for three times, taking out the oak chips, changing thesame type of oak chips, refluxing for three times again, and removing the round-bottom flask so as to obtain an oak extracting solution having the concentration of 240g/L; repeating the S3 until fivedifferent types of oak extracting solutions are obtained; and S5, mixing the five different types of oak extracting solutions according to a ratio, thereby obtaining the brandy. According to the method disclosed by the invention, after the different types of oak chips are extracted, according to the aging characteristics of the brandy, the oak chips are blended into the proportion that the Cognactype is the principal and the other four types are auxiliary types.

Description

technical field [0001] The invention relates to the field of brandy, in particular to a method for extracting aroma substances for preparing brandy. Background technique [0002] Aging brandy in oak barrels can give brandy a smoother taste and rich aroma. Therefore, the division of brandy grades is inseparable from the aging time. The minimum age of X.O is 6 years, the minimum age of V.S.O.P is 4 years, the minimum age of VO is 3 years, and the minimum age of Tier 2 is 2 years. It takes a lot of time and money to produce high-quality brandy. [0003] For the extraction of substances in oak, a more complicated method is to soak oak boards or chips in 60% and 80% alcohol solutions in turn, and finally soak in water to extract various compounds. In order to simulate the oxidation in oak barrels, some researchers soaked and extracted these substances with about 55% alcohol under the condition of aeration of oxygen. There are also some methods that utilize ultrasound and low ...
