Sulfur Notes

Sulfur notes represent aromatic compounds in cannabis that evoke sulphurous, onion-like, or garlic-adjacent sensory profiles. These scents arise from volatile sulfur-containing compounds such as dimethyl disulfide and dimethyl trisulfide, which are also found in certain foods and plants. Sulfur notes are often tagged as secondary or tertiary aromatics in strain descriptions, appearing alongside earthiness or spice. Lineage records frequently report sulfur characteristics in certain Skunk-descended cultivars and plants expressing particular chemotypes. Breeders working in selection programs sometimes encounter sulfur notes as a byproduct of terpene and thiol expression, though intentional breeding for this trait remains less common than selection for floral or fruity aromatics.

Breeders may isolate sulfur-note phenotypes when working with Skunk genetics or chemotypes rich in volatile sulfur compounds. Understanding sulfur expression helps cultivators and geneticists predict aromatic stability across generations and environmental conditions.
