METHOD OF BREWING FLAVOURED LIGHT BEER Russian patent published in 2010 - IPC C12C12/00 

FIELD: chemistry.

SUBSTANCE: invention relates to brewing technology. The method involves mixing dill and hop, extraction of the obtained mixture with liquid nitrogen and separation of the corresponding miscella. Girasol is cut and dried in a microwave field at given process parametres. The girasol is mixed with malt. The obtained mixture is saturated with the separated miscella, while simultaneously increasing pressure. Pressure is then lowered to atmospheric pressure level and the mixture is simultaneously frozen. The mixture then undergoes cryogenic grinding in the medium of the released nitrogen. Water is added and saccharification is carried out to obtain wort. Brewing yeast is added and fermentation and filtration are carried out to obtain the end product.

EFFECT: method shortens duration of the process and increases foam stability of the end product.
