Batch testing

Every batch tested. Every certificate published.

Each bottle carries a batch number, printed on the base below the best-before date. That number resolves to the certificate of analysis for that exact batch.

What a certificate of analysis is

A certificate of analysis is a document produced by a laboratory recording what they tested a specific batch for, the methods used, and the results. It is the difference between a brand telling you a product is what it says it is, and a third party confirming it.

What ours show

  • The laboratory that carried out the testing
  • The date of analysis
  • The batch number, matching the one on your bottle
  • Each analyte tested, the specification, and the result

[PLACEHOLDER — the test panel. This section must state exactly which analytes are tested and to what specification, and must be confirmed with the manufacturer before publication. Do not publish an unverified testing claim.]

Looking up your batch

[PLACEHOLDER — batch lookup module. Requires the batch number format and the location the certificates are hosted.]

If a batch fails

If a batch does not meet specification it is not sold. Where a batch has already shipped and a subsequent result requires it, we will contact affected customers directly and publish the outcome here rather than withdrawing the certificate quietly.
