Aging Chemistry

Aging chemistry refers to the chemical transformations that occur in cannabis biomass over time, particularly during curing, storage, and extended aging. Primary cannabinoids like THC and CBD gradually convert through oxidation and decarboxylation, while secondary metabolites (terpenes, flavonoids, phenolic compounds) degrade or polymerize depending on temperature, light, humidity, and oxygen exposure. Breeders and seed banks track aging chemistry to understand stability of cannabinoid profiles, shelf-life of preserved genetics, and how storage conditions affect the molecular composition of archived plant material. This classification is essential for seed preservation programs and for documenting how strain chemistry drifts across years of storage.

Breeders working with aging chemistry focus on selecting lineages that maintain cannabinoid ratios and terpene expression through extended storage, critical for seed bank archiving and long-term genetic preservation. Understanding aging chemistry helps breeders identify which genetics degrade rapidly versus those showing stable profiles, informing decisions about preservation methods and cryogenic
