Neral Isomer

Neral is one of two geometric isomers of geranial, together comprising the volatile compound geranial/neral (also called citral). These isomers differ in spatial arrangement around a double bond but share similar aromatic profiles—commonly described as lemony, fresh, and citrus-forward. Neral appears in cannabis alongside its isomer geranial, though the precise ratio varies by cultivar and environmental conditions. The presence of citral compounds (geranial + neral combined) is often tagged as a secondary or tertiary terpene marker in breeding records, particularly in strains with pronounced lemongrass or citrus aromatics. Breeders tracking terpene stability across generations frequently monitor isomer ratios, as these can shift during curing and storage.

Growers and breeders working in citral-forward families use neral/geranial ratios as a minor fingerprinting tool to confirm lineage consistency. Selection for stable citral expression helps maintain recognizable aroma profiles across seed generations.
