Post Harvest Volatiles

Post-harvest volatiles refer to aromatic compounds that emerge or transform during cannabis drying, curing, and storage rather than being present in live plant tissue. These secondary metabolites—including various terpenes, esters, and aldehydes—develop through enzymatic degradation, oxidation, and microbial activity in the curing environment. Temperature, humidity, light exposure, and duration of cure significantly influence which volatiles dominate the final profile. Lineage records frequently report that identical genetics can express notably different aromatic signatures depending on post-harvest handling, making curing technique a critical variable in breeding evaluation. Understanding post-harvest volatile development is essential for breeders assessing true genetic potential versus processing artifacts.

Breeders working with phenotypic selection must standardize curing protocols to accurately evaluate aromatic genetic expression across generations. Inconsistent post-harvest conditions can mask or exaggerate terpene profiles, complicating accurate parent selection and F1 hybrid assessment.
