Sesquiterpene Ratios

Sesquiterpene ratios refer to the relative proportions of different C15 sesquiterpenes within a cannabis sample's terpene profile. Common sesquiterpenes include caryophyllene, humulene, and β-myrcene, each contributing distinct aromatic and sensory notes. The ratio between these compounds—rather than their individual presence alone—often determines the overall aroma character and volatility of plant material. Breeders and geneticists track sesquiterpene ratios as a standardized way to classify and preserve strain-specific aromatic fingerprints across generations. Understanding these ratios is essential for consistent extraction work, breeding selection, and lineage documentation. Sesquiterpene-dominant profiles are commonly associated with heavier, spicier, or earthier aromatic expressions.

Breeders use sesquiterpene ratio analysis to stabilize aromatic traits and select parent plants with reproducible terpene signatures. Tracking ratios across multiple generations helps maintain flavor and aroma consistency in established strain lines.
