Terpene Boiling Point

Terpene boiling point refers to the temperature at which individual volatile compounds transition from liquid to vapor phase. In cannabis breeding and processing, boiling points are critical because they determine extraction efficiency, preservation during drying and curing, and flavor/aroma retention in final products. Different terpenes have markedly different boiling points—myrcene around 168°C, limonene around 177°C, and pinene around 156°C—meaning they vaporize at different rates during cultivation, harvest, and consumption. Understanding boiling point profiles helps breeders select for stable aromatic chemotypes and guides processors in temperature-sensitive extraction methods. Lower-boiling terpenes may be lost earlier in heating cycles, while higher-boiling terpenes persist longer, reshaping the overall sensory profile over time.

Breeders monitor boiling point clusters when developing stable cultivars, as terpene volatility affects how aroma and flavor express across different environmental conditions and post-harvest handling. Processors use boiling point data to optimize low-temperature extraction and preservation techniques that maintain the intended terpene ratio.
