FIELD: chemistry.

SUBSTANCE: invention relates to beer brewing technology. The method involves mixing jeera and hop, extraction of the obtained mixture with liquid nitrogen with separation of the corresponding miscella, cutting, drying in a microwave field at given process parametres and roasting girasol-sunflower, mixing girasol-sunflower and malt, saturating the obtained mixture with the separated miscella while simultaneously increasing pressure, reducing pressure to atmospheric level with simultaneous freezing of the mixture, cryogenic grinding in the medium of the released nitrogen, adding sugar, pouring water and saccharification to obtain wort, addition of brewing yeast, primary fermentation, after-fermentation and filtration.

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