FIELD: chemistry.
SUBSTANCE: method provides producing ethanol by ethanol extraction from fermentable wort in a distillation column, wash distillate cleaning from head and intermediate impurities in an epuration column operating by deep hydroselection, epurate rectification in an alcohol column, impurity recovery in a final purification column operating in the mode of re-epuration and purification of fractions containing head impurities and methanol in a head impurity concentration column. The alcohol column, final purification column and head impurity concentration column operate in vacuum and are heated by secondary alcohol water steam from other columns; between the alcohol column and final purification column, there is an ion exchange reaction for recovering impurities having the negative effect on the organoleptic parameters of the end product.
EFFECT: invention enables improving the organoleptic parameters of ethanol, improving its qualities and reducing the production-related energy consumtion.
