Age Related Chemistry

Age-related chemistry refers to how cannabis flower composition changes over time after harvest, as cannabinoids and terpenes undergo oxidation, degradation, or conversion. THC gradually converts to CBN (cannabinol) through oxidative processes, while volatile terpenes decline with exposure to light, heat, and air. Breeders and seed banks study age-related chemistry to understand storage stability, predict shelf-life potency shifts, and develop preservation protocols. This classification is distinct from strain chemistry—it describes the *trajectory* of compounds in cured or stored material rather than initial cannabinoid ratios. Understanding age-related chemistry helps breeders establish baseline stability data and guides collectors on optimal storage conditions.

Breeders use age-related chemistry data to select for cultivars with stable cannabinoid profiles during storage, to test seed longevity and viability retention, and to identify genetic factors influencing oxidative resilience. This knowledge informs breeding goals around shelf-stability and helps establish realistic expectations for stored genetics.
