UMF™ Certification & Independent Lab Testing
Every batch of Happy Valley Manuka honey is independently tested and verified to confirm its authenticity and quality. UMF™ grading reflects the concentration of naturally occurring markers found in genuine New Zealand Manuka honey.
What the UMF™ Mark Represents
The UMF™ mark is a trademarked certification that identifies genuine New Zealand Manuka honey. To carry the UMF™ mark, each batch must be independently tested and verified against strict quality and authenticity criteria.
Unlike single-number systems, UMF™ certification considers multiple naturally occurring Manuka markers, providing a clearer picture of how a particular batch of honey has been graded.
Key Markers Commonly Assessed
Leptosperin
A naturally occurring compound found in Mānuka nectar that is used as a key marker to help confirm the honey’s botanical origin as genuine Mānuka.
DHA (Dihydroxyacetone)
A naturally occurring compound found in Mānuka nectar that, over time, contributes to the formation of MGO as the honey matures.
MGO (Methylglyoxal)
A naturally occurring compound in Mānuka honey that is measured to indicate its concentration level and is commonly displayed on product labels.
HMF (Hydroxymethylfurfural)
A compound measured to assess honey freshness and handling, helping ensure the honey has been stored and processed appropriately.

FAQs
What’s the difference between UMF™ and MGO?
UMF™ is a trademarked certification system that measures multiple naturally occurring markers found in genuine Manuka honey, while MGO refers to the measurement of one specific compound, methylglyoxal. Both are used to help consumers understand how Manuka honey has been graded.
Why are Manuka honey grades different each season?
Manuka honey is a natural product, and factors such as climate, flowering conditions, and harvest location can affect the composition of each season’s honey. As a result, UMF™ grades can vary from year to year.
What does “independently tested” mean?
Independently tested means each batch of Manuka honey is analysed by an accredited laboratory to verify its composition and ensure it meets recognised Manuka standards before being graded and labelled.
Why do higher UMF™ grades cost more?
Higher UMF™ grades are produced in smaller quantities and require more extensive testing and verification. Their limited availability and certification process contribute to a higher price point.
How should I store Manuka honey?
Manuka honey should be stored at room temperature, away from direct sunlight and heat. There is no need to refrigerate honey, as this can cause it to crystallise.
Is Manuka honey from New Zealand only?
Yes. Genuine Manuka honey is produced in New Zealand from the nectar of the native Manuka tree (Leptospermum scoparium), which grows naturally in this region.
