## Abstract The three main microbiological conversions in the production of kaffir beer have been studied, viz.: the souring of the mash by lactic acid bacteria, the alcoholic fermentation of the wort by a variety of yeasts generally present on the malt used in the conversion and, finally, the spoi
Xanthohumol (XN), a component of hops, is lost in significant quantities in the conventional brewing process. In commercial beers less than 0.2 mg XN/L are found. In order to increase the yield of XN in the brewing process, the parameters of XN recovery were studied. During wort boiling, XN is large
