TABLE WINE MATERIAL PRODUCTION METHOD Russian patent published in 2020 - IPC C12G1/02 C12H1/22 

FIELD: food industry.

SUBSTANCE: invention relates to winemaking industry. Method for production of table wine material consists in the fact that preparing a vessel for grape must fermentation by loading oat chips in fermentation vessel at rate of 1–10 g/dm³ of fermenting grape must, processing oak chips with 3 % hydrogen peroxide in amount of 10–100 ml/kg of oak chips, holding processed oak chips for 1–3 hours, filling with acidified tartaric acid to concentration of 5–15 g/dm³ of hot water at rate of 5–15 l/kg of oak chips and holding the obtained mixture for 6–8 hours, in ready to fermentation capacity grape must is added in amount of 30–50 vol. % of design volume, adding of pure culture of yeast is added in amount of 2–3 vol. % of design volume of grape must or dry yeast, fermentation is carried out for 6–12 hours, then adding remaining 70–50 vol. % of grape must from the calculated one and performing fermentation to produce table wine material, wherein fermentation is carried out at temperature of 18–26 °C up to residual sugar 2–3 g/dm³ for 7–10 days, draining the ejected table wine material with yeast.

EFFECT: invention allows to manufacture a product with high organoleptic indices, exclude risk of insufficient fermentation, ensure high microbial stability, increase consumer safety of the product and speed of wine material production.
