Fermentation Pathways

Fermentation pathways in cannabis refer to the biochemical processes that occur during curing and storage, where microorganisms and residual enzymes break down plant material and transform cannabinoids and terpenes. These metabolic routes are influenced by moisture, temperature, oxygen availability, and microbial populations—factors breeders and cultivators monitor to understand post-harvest chemistry. While cannabis fermentation differs from controlled fermentation in food production, similar microbial activity produces organic acids, esters, and volatile compounds that shift the plant's chemical profile over time. Lineage records and breeding documentation increasingly track how different cultivars respond to fermentation conditions, revealing genetic predispositions toward stable or unstable curing outcomes. Understanding fermentation pathways is essential for seed preservation, long-

Breeders working in preservation and seed banking prioritize fermentation stability—selecting for cultivars that resist unwanted microbial colonization and maintain cannabinoid/terpene integrity during extended storage. Genetic lines with robust curing profiles and resistance to degradation are valuable for maintaining seed viability and consistent chemistry in breeding programs.
