Technical field
What the present invention relates to cognac urges old technology, and particularly a kind of redox potential works in coordination with the method for high pressure regulation and control special oak rapid ageing cognac.
Background technology
Along with the progress of society, growth in the living standard, people more and more pay close attention to health diet, and fruit wine is also more and more subject to extensive concern as wine kind human body to unique health-care effect, and cognac is well received by consumers as a kind of fruit wine of higher-end.Cognac need carry out storage ageing in oak barrel, by reaction slowly between oak and wine for wine adds look flavouring, makes wine golden yellow color transparent, mellow.But brandy generally need be preserved for many years in oak barrel, as superfine brandy (X.O) at least will deposit more than 6 years in oak barrel, the superfine brandy of some reputable brands is deposited and is reached more than 15 years.Therefore, in order to improve brandy oak barrel during aging speed, save the oak resource that the world is limited, reduce production cost, shorten the ageing cycle, enhance productivity, the research of brandy ageing method is more and more subject to people's attention, and the old research of urging of brandy becomes brandy fruit wine industry facing challenges.
Original brandy is in oak barrel storage process, original brandy extracts a large amount of aromatoising substances and coloring matter from oak, and a series of physicochemical change occurs, while vinosity maturation, the aroma of ageing and oak perfume are merged mutually, forms the style of brandy uniqueness.But oak barrel is expensive, the French Oak bucket price of 300 liters of sizes is at about 600 dollars, and U.S.'s oak barrel is between 300 ~ 400 dollars, and domestic oak barrel price is Renminbi about 3000 yuan.Except purchasing the expense of oak barrel first, long storage periods brandy also has many problems.As: set up huge wine storehouse, the overstocking of huge storage wine fund, wine cellar daily administration and oak barrel safeguarded, old oak barrel eliminates renewals, wine at lay up period owing to volatilizing and seepage and loss of annual 3% ~ 5% of causing etc., this all further increases productive expense, and therefore natural aging method greatly limit the development of brandy.
What now have report urges old patent more about drinks, and Chinese patent 87105894 discloses a kind of employing and increases wine liquid and the contact area of storing drinking vessel surface, to strengthen the efficient aging technology of aging interfacial drinks and equipment; Chinese patent 95236641 discloses a kind of brandy ageing of wine device adopting infrared rays and oak coke associated treatment; Chinese patent 200810240216.X discloses a kind of electromagnetic effect-enhanced oxygen source ozone air-liquor mixture hydraulic pressure jet flow liquor ageing machine; Chinese patent ZL200920153794.X discloses a kind of high-voltage electric field wine processing device; Chinese patent 200410011304.4 discloses a kind of preaging treatment process and voltage pulse electric field processing device thereof of wine.
