How do you ensure consistency between batches?

We maintain batch-to-batch consistency through controlled sourcing, standardized production, and full QC testing.

Consistency Control System

StageControl
SourcingContracted farms, consistent harvest standards
ProcessingStandardized extraction parameters per batch
QC TestingEvery batch tested: melting point, color, aroma, moisture
DocumentationCOA issued for every batch

What Is Verified Per Batch

  • Melting point range (50–64 °C)
  • Color and appearance
  • Aroma profile (organoleptic check)
  • Moisture content (≤ 3.0%)
  • GC-MS comparison against reference profile

Batch Traceability

Each batch has a unique batch number linked to raw material lots, production date, and test results — full traceability from farm to finished wax.

Request COAs from different batches to compare, or specify a reference batch and we will match it as closely as possible.
