Terpene Fermentation

Terpene fermentation refers to microbial-driven processes that transform volatile monoterpenes and sesquiterpenes into secondary aromatic compounds during cannabis curing and storage. Rather than a plant-based trait, fermentation describes chemical changes occurring in dried flower when anaerobic bacteria and fungi metabolize terpenes under specific moisture and temperature conditions. Breeders and cultivators observe these shifts as part of post-harvest chemistry; strains with certain terpene profiles may undergo more pronounced aromatic transformation during extended aging. Research into cannabis post-harvest biochemistry remains limited, but fermentation-adjacent processes have been documented in tobacco, tea, and wine production. Understanding terpene stability and breakdown helps inform storage practices and predictable flavor development over time.

Breeders often select for strains with robust, stable terpene profiles when designing cultivars intended for long-term storage or aged finished products. Terpene composition—including ratios of limonene, myrcene, and caryophyllene—influences which secondary compounds may form during curing, making terpene screening relevant to cultivar development for specific post-harvest outcomes.
