Alpha Humulene

Alpha-humulene (also called α-humulene or humulene) is a sesquiterpene commonly found in cannabis, hops, basil, and other plants. In cannabis breeding records, strains carrying elevated humulene levels are often associated with earthy, woody, and spicy aromatic profiles. The compound is frequently identified through gas chromatography analysis during strain characterization work. Breeders tracking terpene expression often monitor humulene alongside myrcene and caryophyllene to predict aroma phenotypes. Humulene's presence is typically correlated with specific parent lineages and environmental growing conditions.

Breeders working with hops-derived or Old World cannabis genetics frequently encounter elevated humulene expression. Selection for this terpene is commonly used to stabilize earthy, herbal, and spicy aroma profiles across generations.
