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

FIELD: chemistry.

SUBSTANCE: invention relates to beer brewing technology. The method involves mixing bayleaf with hop. The obtained mixture is extracted using liquid nitrogen with separation of the corresponding miscella. Chicory is cut, dried in a microwave field at given process parametres and roasted. The chicory is mixed with malt. The obtained mixture is saturated with the separated miscella while simultaneously increasing pressure. Pressure is reduced to atmospheric pressure level with simultaneous freezing of the mixture. The mixture is subjected to cryogenic grinding in the medium of the released nitrogen. Drinking water is poured and the mixture is saccharified to obtain wort. Brewing yeast is added to the wort. Primary fermentation, after fermentation and filtration are carried out.

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