METHOD FOR INDUSTRIAL PRODUCTION OF KVASS BEVERAGE Russian patent published in 2017 - IPC C23G3/02 

FIELD: food industry.

SUBSTANCE: invention relates to a method for production of a fermented product capable to mixing with at least a sweetener and water to produce a kvass beverage. Method includes a step (a), of mixing kvass wort with a fermented sweetener, step (b) of performing fermentation of product from step (a) using yeast to obtain ethanol content of 2.5–5 % (vol), at step (c) performing separation of yeast product at stage (b) then stage (d), of distilling fermented separated product of wort from step (c) to produce concentrated wort with dry substances content of at least 65 %, measured in form of refractometric Brix, and a step for thermal treatment of wort concentrate a step (d) to produce a fermented product, which is concentrated fermented kvass wort; or method includes following steps: mixing kvass wort concentrate in an amount of 100 % of fermented sweetener and water to obtain wort with dry substances content 15–34 %, measured in form of refractometric Brix (a1); step for fermentation of product from step (a1) using yeast to obtain 4–8 % (vol/vol) ethanol (b1) and step (c1) for separation of yeast from product from step (b1) to produce a fermented product, which is fermented wort.

EFFECT: method provides a process of fermentation before final mixing of kvass, which enables to carry out process final mixing and final production of kvass outside of fermentative production.
