International Bitterness Units in Wort by Segmented Flow Analysis
The automated procedure for the determination of international bitterness units (IBUs) in wort is based on the following reaction: the wort sample is acidified with hydrochloric acid and then combined and extracted with iso-octane. The emulsified layer is separated, and absorbance is measured at 275 nm.
