Terpene Degradation

Terpene degradation refers to the breakdown of volatile aromatic compounds (terpenes) in cannabis plant material over time, driven by heat, light, oxidation, and microbial activity. Understanding this process is essential for breeders and cultivators working to preserve strain-specific aroma profiles and genetic expression. Terpene loss occurs most rapidly during drying, curing, storage, and processing—particularly when environmental conditions are not controlled. Lineage records frequently report that older seed lines or improperly preserved samples show altered terpene signatures compared to freshly harvested material. Breeders studying terpene stability often compare cultivar performance across different storage conditions to identify which genetics maintain aromatic profiles more effectively.

Breeders working in terpene preservation research cultivars for storage resilience and aroma stability, treating degradation resistance as a selectable trait. Genetic lines showing slower terpene loss under standard conditions are valuable for creating stable seed stock and predictable commercial phenotypes.
