Post Harvest Volatile Compounds

Post-harvest volatile compounds refer to aromatic molecules that develop, transform, or degrade during drying, curing, and storage of cannabis plant material. These compounds result from enzymatic processes, oxidation, and microbial activity occurring after harvest—distinct from terpenes present in fresh flower. Common post-harvest volatiles include various aldehydes, ketones, and secondary terpene oxidation products that can significantly alter the sensory profile of finished cannabis. Understanding these compounds is important for breeding programs focused on stable, predictable aroma development and for preservation strategies that minimize unwanted degradation during cure cycles.

Breeders working on stability and consistency often select for genetic backgrounds that produce favorable post-harvest volatile profiles—strains with predictable curing characteristics and minimal off-flavor development. Controlling environmental factors during drying and cure allows breeders to observe which genetic lines maintain desired aromas or develop desirable secondary notes during process
