Aroma Retention Rating

Aroma Retention Rating is a classification system used by breeders and seed banks to document how well a cannabis plant's volatile terpene profile persists through drying, curing, and storage. This trait is measured qualitatively—often on a scale from low to high—by comparing the intensity and character of fresh plant material against the dried product. Retention varies significantly across strain families; some lineages consistently hold aromatic complexity while others fade noticeably. Environmental factors like temperature, humidity, and curing method also influence retention, making this a hybrid assessment of both genetic potential and post-harvest handling. Breeders track aroma retention as part of phenotype stability documentation, particularly when working with limited seed runs or establishing IBL (inbred line) standards.

Breeders prioritize aroma retention when selecting parents for commercial cultivation, as stable terpene expression directly impacts product consistency and market appeal. Strains with documented high retention are often backcrossed to introduce this stability into new crosses.
