Monoterpenes Vs Sesquiterpenes

Monoterpenes and sesquiterpenes are the two major classes of volatile terpenes found in cannabis. Monoterpenes (C10H16) are smaller, lighter molecules—including limonene, myrcene, and pinene—that tend to evaporate more readily and contribute bright, fresh aromas. Sesquiterpenes (C15H24) are larger, heavier compounds like caryophyllene and humulene that persist longer and often carry earthy, woody, or spicy notes. Breeders and cultivators track the monoterpene-to-sesquiterpene ratio because it influences both aroma profile and preservation stability during storage and handling.

Selecting for monoterpene-dominant profiles produces cultivars with pronounced top-notes and volatile appeal; sesquiterpene-forward lines offer aroma complexity and shelf-life resilience. Understanding this balance helps breeders stabilize desired scent characteristics across generations.
