Terpene Loss

Terpene Loss refers to the degradation or volatilization of aromatic compounds during cultivation, harvest, drying, curing, or storage. Cannabis plants synthesize diverse terpene profiles during flowering, but these volatile organic compounds can evaporate or break down under heat, light, extended storage, or improper handling. Breeders and cultivators often study terpene stability as a preservation trait, seeking genetics that maintain aromatic complexity through the post-harvest lifecycle. Understanding terpene loss mechanisms helps inform decisions about environmental controls, timing of harvest, and curing protocols. This category encompasses both the chemical processes involved and the horticultural strategies used to minimize degradation.

Breeders working in preservation genetics select for lineages and cultivars that demonstrate robust terpene retention, particularly when environmental stress or extended dry-down periods are anticipated. Stability traits are increasingly valued in commercial breeding programs seeking to match the organoleptic profile at point-of-sale with the profile at point-of-harvest.
