FIELD: wine-producing industry. ^ SUBSTANCE: method involves fraction distillation of wine material to obtain cognac alcohol that is enriched with oak extractive substances at increased temperature in battery of hermetically closed and in-line joined tanks containing oak staves after their thermal treatment and under providing the average alcohol concentration in each tank in limits from 40.0°C to 45.0°C. After 10-12 h gaseous oxygen is bubbled into each tank in the amount from 2.5 to 4.0 mg/dm3 of adding alcohol. Alcohol is fed to supply tank joined with atmosphere through alcohol-trapping condenser wherein alcohol is cooled to temperature from 15.0°C to 20.0°C and fed for many seasoning years with treated oak stoves. At the last seasoning year alcohols are blended to uniform set and pumped over into vertical enameled tanks containing oak staves after their preliminary thermal treatment and wherein gaseous oxygen is bubbled at the rate from 1.0 to 2.5 m3/h with periodicity 30-40 days and by maintaining the constant excessive oxygen pressure in the limits from 5.0 to 10.0 KPa in their gaseous chambers. Cognac alcohol is blended, treated by cold, subjected for resting and filtration. Also, invention gives recommendations concerning selection of amounts of tanks in battery, thermal treatment of staves and stacking staves for stack into vertical tanks. Invention provides enhancing organoleptic indices of the ready product and decreasing consumption for it producing. ^ EFFECT: improved producing method of cognac. ^ 4 cl, 11 dwg, 2 tbl, 3 ex |
