QUALITY AND AUTHENTICITY GUIDE
Mānuka honey certificates and grading: your questions
Understand the label, read the laboratory markers and match your jar to its batch certificate.
What is a UMF™ release certificate?
It is a record for the named sample and batch. Scan your label QR code, match the batch code with your jar, and review the certificate ID and results. The laboratory result can be higher than the minimum grade printed on the label.
What does leptosperin testing tell me?
Leptosperin is one marker used in UMF™ quality and authenticity testing. Read the reported batch result alongside MGO, DHA and HMF rather than treating one measurement as the whole quality assessment.
What is the difference between UMF™ and MGO?
MGO stands for methylglyoxal; the accompanying number expresses its concentration in milligrams per kilogram. UMF™ evaluates four quality factors. An MGO number alone is not UMF™ certification, and neither number is a treatment dose.
How do I compare Mānuka honey grades before buying?
Start with the labelled UMF™ grade and MGO value, then check the batch certificate and licensed brand. Compare jar size, price and availability at the retailer. A higher grade is not a promise of a health outcome.
What if my batch number does not match?
Do not assume a certificate for another batch covers your jar. Contact our team with the UMF™ grade and batch code so we can help you locate the relevant record.
