Sesquiterpene Classification

Sesquiterpenes are a class of volatile organic compounds found in cannabis, composed of three isoprene units (C15H24). These larger terpene molecules are typically heavier than monoterpenes and often exhibit more complex, woody, earthy, or spicy aromatic profiles. Common sesquiterpenes in cannabis include caryophyllene, humulene, and beta-myrcene, each contributing distinct olfactory and chemical signatures to cultivar profiles. Sesquiterpene-rich strains are often associated with deeper, more persistent aromas compared to monoterpene-dominant varieties. Breeders and cultivators frequently track sesquiterpene ratios during selection, as these compounds contribute significantly to the overall terpene fingerprint and stability of stored biomass.

Sesquiterpene expression is commonly selected for in breeding programs targeting specific aromatic profiles and smoke characteristics. Cultivators monitor sesquiterpene stability during drying and storage, as these compounds degrade more slowly than volatile monoterpenes, making them valuable markers for long-term cultivar preservation and consistency.
