FIELD: food industry. SUBSTANCE: prior art method for distillation of fermentation products involves heating of source materials, their preliminary depletion in counterflow with heating steam of volatile impurities with separation of vapor phase, partial condensing of the latter with formation of phlegmy and separation of noncondensed vapors of ester aldehyde fraction, subsequent complete depletion of raw material in counterflow with heating steam of alcohol and remaining volatile impurities. The novelty consists in that phlegmy formed during partial condensing of the vapor phase of volatile impurities in the amount of up to 5% of anhydrous alcohol in the raw material is separated as a fraction of unwanted high-boiling impurities while heating steam for preliminary depletion of raw materials from volatile impurities is constituted by water-alcohol vapors produced at the last stages of complete depletion of the raw materials of alcohol and volatile impurities. EFFECT: higher efficiency. 1 dwg, 1 tbl
