During the beer brewing process , bitter tasting cis and trans iso‐α‐acids are generated from the precursor α‐acids found in hops. The absolute configurations of the α‐acid (−)‐humulone and several of its derivatives have now been elucidated by X‐ray crystallography, thus resolving decades of confusion over the humulone isomerization mechanism.
