Post Harvest Terpene Loss

Post-harvest terpene loss refers to the degradation and volatilization of aromatic compounds that occurs after cannabis flowers are harvested, dried, and stored. Terpenes are sensitive to heat, light, oxygen, and time, making preservation a primary concern in breeding and cultivation programs. Environmental factors such as temperature fluctuations, humidity levels, and exposure to UV radiation accelerate terpene breakdown during the post-harvest window. Breeders working with terpene-rich cultivars must account for this natural degradation when selecting parent plants and evaluating genetic potential. Understanding terpene stability has become increasingly important as consumers and researchers seek to preserve the full aromatic and chemical profile of harvested material.

Breeders increasingly select for cultivars with robust terpene production and greater inherent stability, as higher baseline terpene concentrations can better withstand post-harvest losses. Lineage records frequently report that certain strain families demonstrate superior terpene retention compared to others, making this trait a consideration in multi-generational breeding programs focused on qua
