Terpene Loss

Terpene loss refers to the degradation or volatilization of aromatic compounds during cultivation, harvest, drying, curing, and storage. Cannabis flowers contain hundreds of terpenes—the organic compounds responsible for distinctive aromas—but these molecules are sensitive to heat, light, oxygen, and time. Breeders and cultivators track terpene retention as a quality metric, since strains with robust terpene profiles can lose potency and character under suboptimal conditions. Understanding terpene loss is central to post-harvest handling protocols and breeding for stability.

Breeders working in preservation-focused lines often select for plants that maintain terpene expression across environmental stresses and storage periods. Selecting parent plants with high terpene abundance can help offset natural degradation losses in finished cannabis products.
