Drying Curing Terpene Loss

Terpene volatility during post-harvest drying and curing is a central concern in cannabis breeding and cultivation. Most cannabinoid-rich flowers lose 30–70% of their original terpene mass during the first two weeks of drying, depending on temperature, humidity, and airflow. Breeders selecting for terpene retention often prioritize cultivars with higher absolute terpene concentrations at harvest, as these can better tolerate natural losses while maintaining sensory complexity. Curing conditions—typically 55–65% relative humidity and 60–70°F—are designed to slow volatile loss, though no preservation method fully arrests terpene degradation. Understanding terpene loss mechanics informs strain selection for phenotype stability in production environments.

Breeders working on terpene-focused lineages often evaluate post-harvest stability as part of selection criteria, favoring parents that maintain recognizable aromatic profiles after standard drying protocols. Seed stock with high baseline terpene expression may compensate for expected losses, allowing finished products to retain desired flavor signatures.
