Abstract
Reactions of β-acids in wort and in mineral acids and alkali have been investigated. Under acidic conditions colupulone lost isopentenyl side chains forming two isomeric butenols. Under alkaline conditions two after-bitter compounds were formed, the structures of which were elucidated. They were also found in an isomerized hop extract.Keywords
