Terpene Volatilization

Terpene volatilization refers to the process by which volatile terpene compounds evaporate or disperse from cannabis plant material, particularly during drying, curing, storage, and consumption. Terpenes are sensitive aromatic hydrocarbons with low boiling points, meaning they readily convert from liquid or solid state to vapor under ambient conditions. Environmental factors—temperature, humidity, air exposure, and light—directly influence the rate and extent of volatilization. Understanding this process is critical for breeders and cultivators working to preserve strain-specific aromatic profiles, as improper handling can result in significant loss of the terpene composition that defines a cultivar's sensory character.

Breeders selecting for stable terpene expression often prioritize cultivars that retain aromatic volatiles across storage cycles, as this indicates robust biochemical stability. Some breeding programs focus on identifying genetic markers associated with higher absolute terpene production, which can partially offset losses from volatilization during post-harvest handling.
