Cannabinoid To Terpene Ratios

Cannabinoid-to-terpene ratios describe the relative concentrations of cannabinoids (THC, CBD, CBN, etc.) versus volatile aromatic compounds (terpenes) in a cultivar's flower. These ratios vary significantly across strain families and are influenced by genetics, environment, and harvest timing. Breeders and researchers track these relationships because they shape both the sensory profile and the chemical complexity of the final product. Understanding these ratios is fundamental to cannabis genetics documentation, as they reflect underlying biosynthetic pathways and can distinguish between similar-looking cultivars.

Breeders select for specific cannabinoid-to-terpene balances to stabilize desired aromatic and chemical phenotypes across generations. Cultivars with high terpene expression relative to cannabinoid content often develop pronounced aromas early, while those with lower ratios may require longer curing to reveal terpene complexity.
