ABSTRACT:
A method of enhancing the bitterness of beer by oxidation of .beta.-acids obtained from a carbon dioxide extract of hops and introducing the resulting hulupone, preferably at least partially purified, into the beer. The extract contains also .alpha.-acids which are isomerized, separated from the .beta.-acids, and introduced into the beer. The result is a high yield of bitterness-producing material for use in the brewing process.
