Terpenoid Dominance

Terpenoid dominance refers to cannabis plants where volatile aromatic compounds (terpenes) constitute a notably high percentage of the plant's essential oil profile. Rather than a single measurement, terpenoid dominance describes strains where the terpene-to-cannabinoid ratio skews toward aromatic expression, often featuring pronounced scent intensity even before harvest. This classification emerged from breeding observations and lab testing showing significant variation in how much of a plant's resinous output consists of fragrant molecules versus cannabinoids. Breeders and researchers use terpenoid profiling to map genetic expression patterns across generations. Understanding terpenoid dominance helps contextualize why certain lineages are noted for intense aroma despite moderate cannabinoid levels.

Breeders working in aromatic or flavor-focused categories actively select for terpenoid-dominant parents to amplify terpene expression in offspring. High terpenoid dominance can indicate genetic potential for sensory distinction, though it provides no guarantee of specific terpene ratios or stability across environments.
