Post Harvest Dynamics

Post-harvest dynamics refers to how cannabis aroma compounds change during drying, curing, and storage following harvest. During these processes, chlorophyll breakdown, moisture loss, and enzymatic reactions transform the plant's volatile profile—compounds that were present at harvest may degrade, while new aromatic compounds can develop through oxidation and microbial activity. Breeders and cultivators track these shifts to understand how a strain's fresh-flower profile differs from its final cured product. Documentation of post-harvest aroma evolution has become important for strain characterization, since the cured product's terpene expression often differs measurably from live-plant profiles. This knowledge helps breeders select for genetics that develop desirable secondary aromas during the cure phase.

Breeders working with terpene stability and curing characteristics monitor post-harvest dynamics to identify genetics that maintain or develop specific aroma notes during storage. Understanding these changes informs selection for cultivars intended for specific end-use profiles, as some lineages show more pronounced secondary-aroma development than others.
