Oyster plant are cut and dried in microwave field at preset process parametres and mixed with malt at a weight ratio of 1:(40-60). The produced mixture is impregnated with the separated miscella with simultaneous increase of pressure up to a value that corresponds to pressure of saturated nitrogen vapours at the temperature of impregnation. Pressure is reduced down to atmospheric one with simultaneous freezing of mixture, its cryogrinding is carried out in medium of released nitrogen, poured with drinking water and saccharified to produce wort. Beer yeast is added into wort, fermented and filtered to make finished product.
