Post Harvest Terpene Changes

Post-harvest terpene changes refer to the chemical transformations that occur in cannabis plant material after cutting, drying, and curing. During these phases, volatile and semi-volatile terpenes are lost through evaporation, while others undergo oxidation, isomerization, or recombination—altering the aromatic and chemical profile significantly. Temperature, humidity, light exposure, and cure duration all influence which terpenes persist and which degrade. Understanding these changes is essential for seed developers and cultivators working to stabilize desired aromatic traits across generations. Researchers have documented that some terpenes (like myrcene) are more susceptible to loss, while others (like β-caryophyllene) show greater stability. Breeders selecting for terpene consistency must account for post-harvest volatility when evaluating phenotypes.

Breeders working toward stable, reproducible aromatic lineages must evaluate fresh flower profiles separately from cured material to identify terpene stability and loss patterns. Selecting parent plants based on their post-harvest terpene retention helps establish lines where desired aromatic traits persist through typical storage and consumer handling.
