Caryophyllene Chemistry

Caryophyllene (β-caryophyllene) is a sesquiterpene with a molecular formula of C₁₅H₂₄ that occurs naturally across cannabis and numerous botanical species including black pepper, cloves, and hops. In cannabis flowers and trim, caryophyllene typically comprises 0.5–3% of the essential oil fraction, though concentration varies significantly by genotype and cultivation conditions. The compound forms through farnesyl pyrophosphate (FPP) pathways and is commonly associated with peppery, woody, and spicy aromatic notes. Breeders studying caryophyllene-dominant strains often prioritize genotypes with consistent terpene expression across photoperiods and stress conditions. This sesquiterpene is one of the few cannabis-derived terpenes subject to some regulatory attention due to its structural properties and presence in food and fragrance industries.

Caryophyllene expression is a heritable trait breeders select for in flavor and aroma profiling programs. Growers and breeders track caryophyllene levels via gas chromatography to stabilize desirable peppery or woody phenotypes across generations and crosses.
