Sesquiterpene Rich Chemotypes

Sesquiterpene-rich chemotypes are cannabis profiles dominated by C15 hydrocarbons such as β-caryophyllene, α-humulene, and β-myrcene, often contributing earthy, woody, and spicy aromatic profiles. These compounds form in the plant's trichomes during late vegetative and flowering stages, with concentration influenced by genetics, temperature, and harvest timing. Breeders frequently work with sesquiterpene dominance when targeting specific sensory characteristics or studying chemotype stability across generations. Unlike monoterpene-forward profiles, sesquiterpene-rich plants commonly display slower volatile release and more persistent aromatic signatures. Understanding sesquiterpene chemistry is central to modern cannabis breeding programs focused on predictable terpene expression.

Breeders select for sesquiterpene dominance to establish consistent chemotype lines and explore how these compounds interact with other phytochemicals during curing and storage. Sesquiterpene stability is often prioritized in cultivars intended for long-term preservation or detailed chemical profiling studies.
