Description

one

The invention relates to winemaking and can be used in the production of an accelerator made from oak wood for the maturation of alcoholic beverages, such as horse alcohol, whiskey, rum, calvados. Known methods for producing an oak wood accelerator for the maturation of alcoholic beverages are based on extracting excess tannins and resinous substances from oak riveting, giving unpleasant coarse (duel) tones in flavor and taste, and partial oxidation of tannins and lignin located in the surface layer of riveting

A method is known for producing an oak wood accelerator for the maturation of alcoholic beverages, which consists in hydrolyzing wood, impregnating it with ammonia solution, and air oxidation.

The disadvantage of this method is that when extracting alcoholic beverages, there is a gradual extraction of non-oxidized extractive substances from deeper layers of riveting. As a result, drinks get a coarse taste. Longer aging is required to fully extract and oxidize the desired components of oak riveting in the required amount (3-5 years

The purpose of the invention is a more complete oxidation of the beverage components of oak riveting and acceleration of the ripening process.

This is achieved by the fact that before the treatment with ammonia, the riveting is kept in the vessel reactor under a vacuum of mm Hg. After 5 minutes of removal of the main part of the air from the rivets, ammonia is introduced in the gaseous state and the treated rivets are held at a temperature of 20-35 ° C for 0.5-5 ches in an alkaline medium in which the wire t oxidation by oxygen at a temperature of 20-35 ° С for O, 5-3 days.

In addition, ammonia is injected under an overpressure of 0.5-1 MPa, followed by removal of its excess under vacuum.

The essence of the method is illustrated by an example of its implementation.

G1 p and M 8 p. 1OO kg of oak staves with a thickness of 20 mm is placed in a CPR-reactor, with a capacity of 5OO: i, create an aaum of 30 mm i Hg. Art. VI incubated for 5 min. After that, gaseous ammonia is introduced to an excess pressure of 1 atom and kept at the temperature for 1 hour. Next, the pressure is removed and a vacuum of 30 mm Hg is created in the reactor again. In addition, oxygen is introduced into the reactor to an overpressure of 1 bar and maintained at a temperature of 20-25 ° C for 1 day. Then, the oxygen pressure is released, the reactor is opened, the rivets-i are taken out, they are ventilated in air for 1 day, and used to obtain horse alcohols using the reservaire method. At the same time, 3 months is enough for completion of ripening of spirits with the quality of 3-year barrel aging. The use of the proposed method has the following advantages: using gases as oxidizing agents provides oxidation of tannins to lignin and other desirable components in the entire volume of riveting; When this KIM is aged by the method of treated riveting with horse alcohol, additional oxidation is not required during aging, which sharply shortens the maturation period, depending mainly on the extraction of wood. As a result, it is enough to get horse alcohol for 3-5 years in a barrel 2 -3 months of treated wood exposure. The proposed method can be used for DLI accelerated ripening of whiskey, ohm, calvados and other alcoholic beverages, the maturation of which is associated with the extraction and oxidation of oak wood substances.
