Myrcene Oxidation

Myrcene oxidation refers to the chemical degradation or conversion of myrcene, a dominant sesquiterpene in cannabis, through exposure to heat, light, oxygen, and time. This process can transform myrcene's aroma profile from fresh, herbal, and piney notes toward more earthy, musky, or clove-like characteristics. Breeders and researchers track myrcene stability as part of terpene preservation studies, since oxidation rates vary by cultivar, storage conditions, and post-harvest handling. Lineage records frequently report that certain Indica-leaning genetics show faster myrcene degradation compared to Sativa-dominant strains, though individual plant expression remains variable. Understanding myrcene oxidation is relevant to seed banking, long-term preservation protocols, and predicting sensory drift in stored flower or extract materials.

Breeders working in terpene stability and shelf-life optimization pay attention to myrcene oxidation rates when selecting parent genetics. Cultivars bred for durability in long-term storage or for consistent aromatic profiles across growing seasons often carry lineages selected partly for slower myrcene conversion.
