Post Harvest Volatility

Post-harvest volatility refers to the rapid changes in aroma profile that occur during drying, curing, and storage of cannabis flower. As moisture content decreases and plant enzymes remain active, volatile organic compounds (VOCs) oxidize, hydrolyze, and recombine, shifting the sensory character significantly from fresh material. Breeders and cultivators commonly observe that strains with high terpene diversity exhibit more pronounced aromatic shifts during the post-harvest window. Documentation of these changes is important for understanding a strain's intended final expression, as the aroma at harvest typically differs substantially from the aroma at 2–4 weeks of cure. Strains with stable terpene profiles tend to show less volatility, while those with linalool, limonene, or myrcene-dominant profiles often display more dramatic transformation.

Breeders working toward stable, marketable aromatic expressions often select for genotypes that show predictable post-harvest development rather than extreme volatility. Cultivators use post-harvest volatility data to optimize drying and curing protocols, helping stabilize desired aroma characteristics across multiple harvests of the same strain.
