Terpene Preservation: Protecting the Volatiles You Grew
Terpenes are volatile and heat-fragile — where they peak, how late-flower heat and light quietly bleed them off, and the environmental band that carries aroma from the plant into the jar.
Aroma is the most fragile thing in the room
Terpenes are the volatile aromatic compounds — monoterpenes like myrcene and limonene, sesquiterpenes like caryophyllene — synthesized and stored in the trichome heads alongside cannabinoids. They are the single best differentiator of quality: on a COA, total terpenes of ~1–3%+ signal strong flower and >2% is standout. But unlike cannabinoids, which are relatively stable, terpenes are volatile by definition — they evaporate. Every degree of unnecessary heat and every extra day of harsh light in late flower quietly bleeds them off. Your job in the finish is preservation, not production.
