Volatile Terpene Loss

Volatile terpene loss refers to the degradation or evaporation of aromatic compounds during cannabis cultivation, processing, storage, and handling. Terpenes—the organic molecules responsible for aroma and flavor—have varying vapor pressures; more volatile compounds like limonene and pinene evaporate more readily than heavier sesquiterpenes. This process accelerates with heat, light exposure, oxygen contact, and extended time. Breeders and processors studying terpene retention must account for post-harvest losses when selecting phenotypes or optimizing preservation techniques.

Breeders working on terpene stability often select for cultivars with higher proportions of less-volatile sesquiterpenes or employ controlled drying and storage protocols to preserve target aromatic profiles. Understanding which terpenes are most prone to loss helps guide selection criteria when developing strains intended for specific end-use applications.
