Post Harvest Terpene Retention

Post-harvest terpene retention refers to the preservation of volatile aromatic compounds after cannabis flowers are harvested and dried. Terpenes begin to degrade immediately after cutting due to oxidation, light exposure, heat, and microbial activity. Breeders and cultivators track which lineages and phenotypes maintain terpene profiles more effectively through standard drying and storage conditions. Cultivars with dense trichome development and certain genetic backgrounds often show more stable terpene retention over time. This trait is primarily a matter of horticultural technique—proper temperature, humidity, darkness, and curing duration—rather than a singular genetic expression. Understanding post-harvest handling is essential for preserving the aromatic complexity that defines a strain's sensory profile.

Breeders select for traits like waxy cuticles, thick calyx structures, and robust trichome profiles that may support terpene stability, though post-harvest retention is driven largely by environmental management rather than genetics alone. Lineages from high-altitude or harsh-climate origins are often noted for terpene resilience, making them valuable parents in breeding programs focused on aromat
