Terpene Thermolability

Terpene thermolability refers to the temperature sensitivity of volatile aromatic compounds in cannabis, where certain terpenes degrade, evaporate, or transform when exposed to heat during cultivation, drying, curing, or extraction. Limonene, pinene, and myrcene are commonly associated with higher volatility and thermolabile behavior compared to more stable terpenes like caryophyllene. Breeders and cultivators working in this category document how plant genetics, phenotype expression, and environmental conditions (particularly drying temperatures) influence which aromatic compounds remain stable in the final product. Understanding thermolability is relevant for preservation-focused breeding lines and for producers seeking consistency in terpene profiles across batches.

Breeders select for genetic stability in terpene production to preserve desired aroma profiles after post-harvest handling. Lineage records frequently report that cultivars bred for low-temperature drying tolerance or slow-cure genetics retain volatile terpene ratios more effectively than fast-dried material.
