UMF™ Certification

The gold standard for authentic Mānuka honey.

Every jar of Wilderness Valley honey is independently tested, graded, and certified by the UMF™ Honey Association before it leaves our hands.

Manuka Honey UMF Certification

The most trusted way of identifying the qualities special to Manuka honey is UMF™ certification (Unique Manuka Factor). It is an independent and the most respected Manuka honey organisation in New Zealand.

The UMF™ does not only certify the content of the MGO (Methylglyoxal - discovered by German researchers) but also tests other signature factors crucial to Manuka honey strength and quality: Leptosperin and DHA.

Each batch of our Manuka honey products undergoes stringent independent laboratory checks before being graded and certified.

About our Honey

Why UMF™ certification is the most trusted?

The UMF grading system appraises natural markers found in Manuka honey and assures its activity and purity.

The UMF™ Honey Association has a world-leading science programme focused on identifying the unique signature compounds of genuine Mānuka Honey to safeguard consumers and the industry. In addition, a large body of international research collectively provides consumers and fellow researchers with a wealth of information about this product.

As part of the UMF™ Honey Association testing process, every batch of honey must also go through a series of additional checks and balances to ensure the ultimate authenticity, quality and safety. In addition, all UMF™ licence holders undergo an independent audit to meet stringent production, manufacturing, sampling, and handling standards.

So when you see the UMF™ quality trademark, you can be sure you are buying the best, 100% natural Manuka honey.

About the grading system

Manuka honey beekeeping in New Zealand

Not all Mānuka is created equal.

The UMF™ (Unique Mānuka Factor) grading system is the most trusted way to verify the quality and authenticity of genuine Mānuka honey. UMF™ testing measures three naturally occurring compounds that only appear together in authentic New Zealand Mānuka:

Leptosperin — Found exclusively in Mānuka nectar. Its presence confirms the honey's genuine origin.
DHA (Dihydroxyacetone) — A precursor to MGO, naturally present in Mānuka nectar. Higher DHA indicates fresher, more potent honey.
MGO (Methylglyoxal) — The primary active compound. The higher the MGO, the more potent the honey.

Every UMF™ licence holder completes independent audits covering production, manufacturing, sampling and handling. There are no shortcuts.
