Post Harvest Phenotype

Post-harvest phenotype describes the aromatic and structural changes cannabis plant material undergoes during drying, curing, and storage processes. Unlike fresh-plant aromas, post-harvest phenotypes emerge as chlorophyll degrades, moisture content shifts, and microbial activity—including beneficial mold species—transforms volatile terpene profiles. Breeders and cultivators document these shifts to understand which genetic lines develop desirable aged characteristics, such as intensified fruit, floral, or earthy notes. Post-harvest phenotype expression varies significantly based on temperature, humidity, light exposure, and curing duration, making it a distinct analytical category from the plant's living-stage aroma profile. Lineage records frequently note whether specific crosses are valued for their post-harvest aromatic development or stability.

Breeders working with heritage or landrace genetics often select for stable post-harvest phenotypes, as certain lineages are known to develop complexity during curing that fresh-plant assessment alone cannot predict. Understanding post-harvest aroma transformation helps inform preservation protocols and storage recommendations across seed collections.
