How consistent is the quality between batches of this litsea cubeba oil?
Batch-to-batch consistency is tightly controlled because the oil is produced from a single well-managed feedstock area (Jiangxi, ~45% of world production) with the same distillation line, the same cohobation practice and a GC-based release gate. Typical batch variation is small: citral stays within ±2% of the contracted window, and the odour profile is approved by sensory panel against the retained reference sample.
Consistency Measures
| Control | Approach |
|---|---|
| Feedstock | Fixed sourcing from Jiangxi core orchards; intake screening each season |
| Process | Same steam-distillation line, cohobation and filtration practice |
| GC release | Citral within ±2% of the agreed window on every batch |
| Sensory | Nose-panel comparison against a retained master reference |
| Physicochemical | Density, RI, rotation checked to tight in-house tolerances |
| Documentation | Batch number on COA + sealed retained reference for 36 months |
- When blending is unavoidable (very large orders), we pre-blend and re-release a single COA so you receive one uniform lot
- The annual crop change (July-September harvest) can shift colour marginally, but the citral content and aroma remain on spec
- Ask for our batch-history chart — we can show you several consecutive batches side by side
