Post Harvest Aroma Evolution

Post-harvest aroma evolution describes the chemical changes that occur in cannabis flowers after cutting and during the drying, curing, and storage phases. During these processes, chlorophyll breakdown, enzymatic activity, and microbial interaction can generate new volatile compounds and modify existing terpene profiles. Terpenes may oxidize, polymerize, or transform into secondary metabolites, creating aromas distinct from fresh plant material. This family is particularly relevant to breeding programs focused on developing cultivars with desirable cured-state characteristics rather than fresh-cut profiles. Understanding post-harvest chemistry helps breeders predict how their genetics will age and what aromatic compounds will become dominant after proper curing.

Breeders working in this category study how precursor compounds and enzymatic profiles in raw flowers influence final cured aroma. Cultivars bred for stable or enhanced post-harvest aromatic profiles often show specific terpene combinations and microbial activity compatibility.
