Cinnamaldehyde Expression

Cinnamaldehyde expression refers to cannabis lineages selected or bred for elevated levels of cinnamaldehyde, an aromatic compound that contributes spicy, cinnamon-like, and warm sensory notes. This terpene is commonly associated with certain landrace and hybrid populations, particularly those descended from Asian and South Asian cannabis varieties where such aromatic profiles appear more frequently. Breeders track cinnamaldehyde alongside other volatile compounds to map flavor chemistry across generations. Expression levels vary significantly based on genetics, growing conditions, and harvest timing, making this trait relevant for those studying cannabis terpene diversity and aroma classification.

Breeders working in terpene-forward programs often isolate cinnamaldehyde-dominant lines to develop distinctive aromatic phenotypes and to understand how this compound co-segregates with other traits. Cinnamaldehyde expression can be combined with other terpene goals in crosses to expand a breeding portfolio's sensory range.
