METHOD FOR PRODUCTION OF TABLE WHITE WINE WITH RESIDUAL SUGAR Russian patent published in 2020 - IPC C12G1/02 C12G1/04 C12G1/08 

FIELD: wine industry.

SUBSTANCE: method for production of white table wines with residual sugar includes obtaining wort, its sulphitation, clarification, subsequent multi-step fermentation and filtration, wherein wort is sulphated to 180–200 mg/dm³ of total sulfur dioxide, fermentation of wort is carried out by spontaneous grapes microflora in two steps: first, at temperature of 18–20 °C to concentration of residual sugar 50–80 g/dm³, after which the yeast is separated from the fermenting wort by filtration through membrane filters with pore size of 0.5–1 mcm, then at temperature of 4–6 °C to desired concentration of sugars, after which the wine material is cooled down to 0–+2 °C is held at this temperature for 8–10 days, after which it is filtered at 0–+2 °C through diatomite filters.

EFFECT: invention allows to improve organoleptic indices of the product, preserve the extractivity and enhance the wine stability.
