Brewing process of red apricot brandy
Technical Field
The invention relates to the field of wine brewing processes, in particular to a brewing process of red apricot brandy.
Background
The red apricot is a special product of the American lending summons in the inner Mongolia Baoto city, has orange red to dark red peel, orange yellow pulp, fine pulp, pine, sand, less fiber, more juice, sweet and sour taste, strong apricot taste, various organic components, vitamins and inorganic salts necessary for human bodies, higher nutritional value and is one of the most popular fruits. As the apricots belong to seasonal fruits, the maturity period is short, the apricots are not easy to preserve and store, and the harvested apricots have soft pulp at normal temperature, so that the commodity of the apricots is reduced, and the economic value and the industrial development of the apricots are seriously influenced. At present, the fresh fruits are mainly eaten or processed into cans, preserved fruits and the like, but partial nutrient substances are damaged and lost through processes of high-temperature sterilization, constant-temperature drying and the like, and the fresh fruits can be stored for a long time only by adding additives such as preservatives and the like.
Brandy, originally from Brandewijn, the netherlands, means "burnt wine". In a narrow sense, it refers to a wine obtained by distilling a wine obtained by fermenting a grape to obtain a high alcohol, and storing the high alcohol in an oak barrel. In a broad sense, brandy is a distilled liquor which is brewed by taking fruits as raw materials through fermentation, distillation and storage, and comprises grape brandy, apple brandy, cherry brandy and the like.
The processing technology of the apricot wine base wine is simple and random, and a unique processing technology is not established according to the sugar-acid ratio, soluble solid, organic acid and the maturity of fruit pulp of apricot fruits. In the prior art, SO2 is often added in the fermentation production process of the apricot wine to play the effects of resisting oxidation, inhibiting bacteria and the like, however, the residue in the apricot wine base is not good for the health of human body, and the content of brandy acetaldehyde and aldol is increased in the distilled wine to cause the final brandy to have a sulfur taste.
Most of apricot brandy on the market at present is prepared by blending edible alcohol and apricot essence or soaking fruits, so that the market is disturbed by false truth and fish eyes, the product quality is poor, and the health of consumers is adversely affected due to excessive use of food additives. A small number of apricot wines are obtained by distillation, but in order to save production cost, the apricot wine base wine has simple processing technology, unobtrusive fragrance and wine body defects, the apricot raw brandy obtained by distillation is not aged by an oak barrel, has poor appearance clarity and poor color, does not have red apricot aroma and oak aroma, and has poor, not elegant, soft, mellow and mature taste.
