Preservation Methods

Terpene preservation refers to cultivation and storage techniques designed to maintain volatile aromatic compounds in cannabis flower and biomass. Terpenes—limonene, myrcene, pinene, and others—are susceptible to degradation from heat, light, oxygen, and time. Preservation methods span the entire supply chain: post-harvest handling (temperature control, darkness, inert atmosphere), curing protocols, and long-term storage in sealed, cool conditions. Breeders and producers working with terpene-rich cultivars must account for these preservation challenges when evaluating phenotypes and planning extraction or fresh-frozen processing workflows. Understanding terpene stability is essential for maintaining the chemical integrity of cannabis genetics across generations and commercial applications.

Breeders selecting for high terpene expression must also consider stability traits—how well a cultivar's volatile profile holds up during standard drying, curing, and storage. Cultivars bred for extraction-focused workflows (fresh-frozen or live rosin lineages) are often chosen partly for their ability to maintain terpene richness under low-temperature processing, while traditional flower breeding
