Post Harvest Stability

Post-harvest stability refers to a cannabis plant's biochemical resilience during drying, curing, and storage—the period when volatile compounds degrade, cannabinoids oxidize, and aromatic profiles shift. This trait is influenced by initial terpene concentration, ambient humidity, temperature consistency, and the plant's natural antioxidant capacity. Breeders and cultivators monitor stability by tracking terpene retention rates and cannabinoid degradation over weeks to months post-harvest. Strains with robust post-harvest stability typically maintain more consistent potency and aroma profiles across storage timelines. This is distinct from fresh plant terpene expression and reflects the genetic and environmental factors that determine long-term product quality.

Breeders select for post-harvest stability by evaluating parent lines for resilience to oxidative stress and terpene volatilization. Strains bred for commercial scale production or extended shelf-life often prioritize genetic markers associated with slower cannabinoid degradation and terpene loss.
