Myrcene Caryophyllene Ratio

The myrcene-to-caryophyllene ratio describes the relative abundance of two major sesquiterpenes in cannabis terpene profiles. Myrcene, a monoterpene with herbal-woody notes, typically comprises 20–60% of total terpene content in many cultivars, while caryophyllene, a spicy-peppery sesquiterpene, usually ranges from 5–15%. This ratio varies significantly between strain families and is shaped by both genetic background and cultivation conditions. Breeders and lineage records frequently report that higher myrcene ratios are associated with certain indica and hybrid families, whereas balanced or caryophyllene-leaning profiles appear in heirloom sativas and modern chemotype selections. Understanding this ratio helps contextualize terpene-focused breeding work and genetic stability across generations.

Breeders working in terpene profiling often select parent plants based on myrcene-caryophyllene ratios to stabilize aromatic signatures across seed lines. Crosses targeting specific ratios enable more consistent sensory and chemical phenotypes, particularly in breeding programs focused on chemotype stabilization and preservation of heritage genetics.
