Temperature And Terpene Volatility

Terpene volatility—the tendency of aromatic compounds to evaporate or degrade—is directly influenced by temperature conditions during cultivation, drying, curing, and storage. Most cannabis terpenes have boiling points ranging from approximately 150°C to 220°C, meaning heat exposure can strip or alter the aromatic profile before harvest or consumption. Environmental control during the final weeks of flowering, post-harvest handling, and long-term storage significantly impacts terpene retention. Breeders and cultivators monitor temperature stability to preserve strain-specific terpene expressions, as excessive heat commonly results in loss of more volatile compounds like limonene and pinene while leaving heavier sesquiterpenes relatively intact.

Breeders working with terpene-rich cultivars often select for environmental resilience and consider cold-storage genetics when developing lines intended for terpene stability. Understanding volatility helps producers design preservation protocols and informs decisions about harvest timing, post-harvest temperatures, and packaging materials used to maintain genetic terpene signatures.
