Temperature Dependent Volatility

Temperature-dependent volatility describes how terpene compounds shift their evaporation rates and aromatic expression based on environmental heat. Most cannabis terpenes are volatile organic compounds with specific boiling points—limonene at ~176°C, myrcene at ~168°C, and pinene at ~155°C—meaning they release or concentrate differently across temperature ranges. This principle is critical in cultivation, post-harvest handling, and consumption methods, as heat during drying, curing, or smoking can accelerate terpene loss or alter the final aromatic profile. Cannabis stored in warm conditions typically shows faster terpene degradation compared to cool, dark environments. Breeders and cultivators often monitor this trait when developing strains intended for specific preservation or consumption methods.

Breeders selecting for stable terpene retention often prioritize strains with higher-boiling terpenes or terpene blends that remain stable across typical grow-room and storage temperature ranges. Understanding volatility patterns helps inform decisions about drying temperatures, curing duration, and storage conditions to preserve the genetic expression intended by the breeder.
