How do you ensure consistency between batches?

Question

Accepted Answer

We control consistency with four locked steps: standardized raw-flower sourcing, fixed distillation parameters, post-distillation blending to specification, and GC-MS fingerprint verification on every batch. Consistency Control Control PointMeasureRaw materialContracted farms, grade per NY/T 2303-2013ProcessFixed steam parameters, same stills, monitored cyclesBlendingCross-lot blending to a target marker profileVerificationGC-MS fingerprint + sensory panel on every batchEach batch is compared against the master chromatographic profile; key markers (linalool, linalool oxide, α-terpineol, geraniol) must fall inside set tolerance windows or the lot is re-blended or rejected. The COA records the actual values, so your QC can compare incoming lots against the same master.Request a three-batch consistency package (three GC-MS fingerprints + COAs) to verify lot-to-lot stability before you commit to a program.
