Steam-volatile, pentane-soluble concentrates collected form wort and beer were analyzed by gas chromatography. Two hop oil components, methyl dec-4-enoate and methyl deca-4,8-dienoate, were identified in wort. Evidence is presented to demonstrate that these compounds are probably trans-esterified during fermentation, and that they appear in the final product as the ethyl esters.
