Post Harvest Terpene Chemistry

Post-harvest terpene chemistry describes the volatile compound changes that occur after cannabis flowers are dried and cured. During this period, cannabinoids remain relatively stable, but terpene profiles shift significantly through oxidation, isomerization, and microbial activity. These transformations can alter aromatic profiles, convert monoterpenes to sesquiterpenes, and create secondary compounds not present in fresh material. Understanding these processes is foundational for breeders selecting for stable, storage-resistant genetics, and for cultivators developing curing protocols that preserve desired volatile signatures. Lineage records frequently document how specific cultivars exhibit particular post-harvest stability or degradation patterns. This chemistry also informs seed preservation strategies, as terpene integrity directly affects long-term seed viability assessment.

Breeders working in this category select for genetic backgrounds that maintain terpene stability during standard drying and curing windows, or conversely, favor cultivars that develop desirable secondary aromas through controlled post-harvest transformation. Knowledge of these chemical pathways helps geneticists predict how phenotypes will express over storage time and guides development of cultiv
