Aroma characterization of regional Cascade and Chinook hops (Humulus lupulus L.)

Aroma compounds in Cascade and Chinook hops harvested from multiple Virginia locations were identified by gas chromatography-mass spectrometry-olfactometry (GC-MS-O) aroma extract dilution analysis (AEDA). Selected quantitated combination of stable isotope (SIDA) standard addition method (SAM). A total 33 aroma-active detected five samples with β-myrcene, methyl octanoate, geraniol linalool being the predominant based on their high flavor (FD) factors odor activity values (OAVs). L-Calamenene germacrene B was major characteristic component unique to variety, respectively. Principal (PCA) showed distinctive profiles for all except Blacksburg Petersburg Cascade. Hierarchical cluster (HCA) reflected higher contents most Meadowview when compared counterparts. The significant variations suggested potential influences environmental agronomic practices hop quality.
