Anaerobic Fermentation

Anaerobic fermentation is not a terpene itself, but rather a post-harvest biochemical process that occurs when cannabis plant material is stored in low-oxygen conditions. During this fermentation, bacteria and fungi break down plant compounds, potentially increasing volatile aromatic molecules and altering the original terpene profile. Breeders and cultivators studying preservation methods have documented that anaerobic conditions can shift terpene ratios—sometimes concentrating certain esters or producing novel aromatic compounds not present in fresh material. This process is distinct from standard drying and curing, and has been explored by some growers as an alternative fermentation technique, though outcomes are highly variable and dependent on moisture, temperature, and microbial activity.

Cannabis geneticists and seed preservation researchers monitor anaerobic conditions as a storage variable that can degrade or transform terpene expression over time. Understanding how fermentation affects stored genetics informs decisions about seed longevity, clone banking, and the stability of aromatic phenotypes across generations.
