How do you ensure batch-to-batch consistency of this Nardostachys spikenard oil?

Every batch is released against a strict internal specification: GC-MS fingerprint matching (valeranone and spathulenol within the agreed range; key markers calarene/nardosinone/α-cedrene reported), physical constants (density, RI, rotation) within limits, and sensory check by our perfumer panel. Multi-source lots are blended (pooled) before release to smooth natural variation; batch COA shows ±15% tolerance on markers unless a tighter contract specification is agreed.
