Terpene Monoterpenes

Monoterpenes are the lightest, most volatile class of terpenes found in cannabis—smaller molecules containing 10 carbons that readily evaporate at low temperatures. Key monoterpenes include limonene (citrus), myrcene (earthy, herbal), pinene (pine, sharp), and terpinolene (floral, woody). These compounds are often the first aromatic notes detected in fresh flower, contributing to the initial smell profile before more complex terpenes develop. Monoterpenes are frequently studied in breeding programs for their role in early-stage aroma expression and their prevalence across diverse cannabis lineages.

Breeders select for monoterpene expression to develop distinct early-nose profiles and stability across grows. High monoterpene strains often show faster volatilization during cure, making them useful markers for aroma-focused breeding strategies.
