Post Harvest Volatilization

Post-harvest volatilization refers to the loss or transformation of volatile aromatic compounds that occurs after cannabis flowers are harvested, dried, and cured. During these processes, terpenes and other low-boiling-point molecules can evaporate, oxidize, or convert into different chemical forms—altering the final aroma profile compared to fresh plant material. Factors including temperature, humidity, light exposure, and storage duration significantly influence the degree and direction of volatilization. Breeders and cultivators commonly track how specific strain genetics retain or lose particular terpene signatures through post-harvest handling. Understanding volatilization is essential for accurate genetic documentation, since the "wet nose" aroma often differs substantially from the cured product's scent profile.

Breeders working with aroma stability select for genetics that preserve desirable terpene profiles through standard drying and curing protocols. Strains bred for robust volatile retention help establish consistent, reproducible aroma records in seed catalogs and breeding databases.
