Manuka Honey UMF®

Manuka Honey UMF®


New Zealand Manuka honey is recognised around the globe — not only for its deliciousness, but also for its incredible health benefits. But are all Manuka honeys made equal? Sadly the answer is no, but there is a rating system that can help you purchase the right Manuka honey!


What is UMF® Manuka Honey?

Methylglyoxal (MGO) is one of Manuka honey’s secret ingredients and is the reason why New Zealand Manuka honey is seen as a healthy super food. Although its scientific name may make it sound like it is a man-made creation — methylglyoxal occurs naturally and is found in high-quality UMF® Manuka honey.

UMF® is a grading system that measure the level of methylglyoxal present in honey. The UMF® logo found on selected Manuka honey products (such as Mossop’s UMF® Manuka range) is a quality trademark and a sign of higher-grade honey.

It is important to note that not all Manuka honey is made equally — certain Manuka honey ranges may not meet the UMF® threshold and are considered to be of a lower grade. Always look for the UMF® logo for the best Manuka honey.

How Does the Manuka Honey UMF® Rating Work?

For the best Manuka honey always choose UMF® labelled Manuka honey to ensure you are getting the best possible product.

The higher the UMF® rating the higher the occurrence of methylglyoxal and therefore, the higher the grade of Manuka honey.

The highest quality Manuka honey ranges from UMF® 5+ to 20+ and the majority of these grades are available via Mossop’s UMF® Manuka Honey NZ online store.

UMF 20+ 829 20
UMF 15+ 514 15
UMF 10+ 263 10
UMF 5+ 83 5

*MGO is measured as mg/kg (ppm)
**NPA is measured as % solution (%w/v) of phenol/water
