Post Harvest Volatiles

Post-harvest volatiles are secondary metabolites that develop, intensify, or transform during drying, curing, and storage of cannabis biomass. These compounds include terpenes, esters, and other aromatic molecules that emerge as a result of enzymatic activity, oxidation, and microbial processes after harvest. Unlike primary terpenes present in living plant tissue, post-harvest volatiles often reflect curing conditions, temperature, humidity, and time. Breeders and cultivators track these compounds because they contribute substantially to the final aromatic and flavor profile of finished material. Understanding post-harvest volatility is essential for seed-line documentation, breeding for storage stability, and predicting how a phenotype will mature during the cure cycle.

Breeders working in this category select for genetic traits that produce robust precursor compounds during growth, which then develop favorably during curing. Stability of volatile profiles across different post-harvest environments is a trait of interest for commercial seed lines and for preservation programs.
