BEER PRODUCTION PROCESS Russian patent published in 2001 - IPC

FIELD: brewery. SUBSTANCE: process of production of semi-dark beer using unmalted raw materials involves preparing mash from light barley brewery malt, candy malt with unmalted raw material additive in the form of corn groats. Mash is further saccharified and filtered to give wort, which is boiled with hops and extra sugar, cooled, fermented and after-fermented. When preparing mash, 85-95% of light barley brewery malt, 1-3% of dark or candy malt, and 3-7% of corn groats based on the weight of grain material are used. Mash is prepared via separate single-boiling method: simultaneously preparing boiled product from 15-20% of light barley malt, 1-3% of dark or candy malt, and 3-7% of corn groats and major mash from 70-75% of light barley malt in separate kettles. The latter operation begins with heating boiled product to boil followed by boiling and pumping product into major mash, whereas boiling of hopped wort is carried out with addition of 2-4% sugar. EFFECT: improved organoleptic characteristics of beer enriched with biologically-active substances and simplified process. 1 tbl, 3 ex
