METHOD FOR PRODUCTION OF DEALCOHOLISED WINE Russian patent published in 2025 - IPC C12G1/14 C12H3/02 

FIELD: wine industry.

SUBSTANCE: disclosed is a method of producing dealcoholised wine, which involves evaporation of dry wine to obtain a wine concentrate and a distillate fraction with aromatic substances contained therein, separation of this fraction of the distillate with extraction of the alcohol fraction and the fraction of aromatic substances, mixing wine concentrate and fractions of aromatic substances and subsequent stabilization of alcohol-free wine, wherein dry wine evaporation is carried out in an evaporator reactor under vacuum of minus 94 kPa at temperature of 25-27 °C, the obtained distillate fraction with aromatic substances contained therein is subjected to double distillation under vacuum of minus 94 kPa at temperature of 23-24 °C with separation of ethyl alcohol and extraction of fractions of aromatic substances by means of combined two-stage low-temperature direct-flow refrigerator with temperature of cooling agent to minus 42 °C, wine concentrate is combined with the extracted fraction of aromatic substances, brought with concentrated grape wort to weight concentration of sugars from 4.0 g/dm³ to 18.0 g/dm³ in semi-dry wine, from 18.0 g/dm³ to 45 g/dm³ in semi-sweet wine and stabilized by treatment with gluing substances, followed by filtration and introduction of antioxidants and/or carbon dioxide.

EFFECT: invention enables to obtain a product with a volume fraction of ethyl alcohol of less than 0.5% and having organoleptic characteristics close to those of the initial wine.
