Cure Fermentation

Cure fermentation refers to the biochemical processes occurring during the post-harvest drying and curing phase of cannabis flower, where microbial and enzymatic activity breaks down chlorophyll, starches, and other compounds. During this period, anaerobic and aerobic microorganisms colonize plant material, producing secondary metabolites and volatile compounds that contribute to final aroma and terpene profiles. Temperature, humidity, and air exchange during cure directly influence which volatile compounds develop and persist. Breeders and cultivators track how different genetics respond to fermentation dynamics, as some lineages produce markedly different aromatic outcomes depending on cure conditions. This process is distinct from the living plant's terpene synthesis and represents post-harvest chemistry shaped by both genetics and technique.

Breeders working with fermentation-sensitive lines evaluate how genetic backgrounds affect cure-phase terpene stability, microbial colonization patterns, and aroma development. Understanding cure fermentation profiles helps breeders select for genetics suited to specific curing methodologies or climate conditions.
