UMF™ Manuka Honey

Ancient Wisdom Meets Modern Science

The UMF™ Mark

UMF™ stands for 'Unique Manuka Factor', and is a quality trademark owned and managed by the UMF™ Honey Association. The UMF™ grading system evaluates natural markers found in Manuka honey.

What makes Honey special?

For millennia Honey has been regarded as a special food; its use is espoused in numerous ancient texts from around the globe. This ancient knowledge has now been proven by scientific research.

The first scientific studies into the special properties of honey took place at the end of the 19th century. Some of this early research pointed to honey’s acidity or its osmotic effect as being the source of the special properties of honey.

During the mid-20th century, scientists identified enzymes present in nectar and introduced by bees in the ripening process of honey. Scientists then discovered that when honey was diluted these enzymes gave the honey distinctive properties. However, it was also discovered that these enzymes quickly broke down with exposure to light.

The UMF™ Manuka Difference

In 1981 Dr. Peter Molan began his research into the unique properties of honey. His research led to the discovery of properties in some honey that were not based on any of the previously known factors; of these varieties, New Zealand Manuka honey appeared to be the most promising.

UMF™ - A Measure of Quality

Research to identify the components of Manuka Honey responsible for its unique properties began in 1990. Since then numerous studies have been undertaken around the globe, and a number of these components have been identified.


In 2013 the UMF™ Honey Association began work on the Manuka ID Project; the primary aim of this ongoing project is to determine a profile of Manuka Honey. The association has collected samples of nectar and honey from all of New Zealand and is utilising state-of-the-art chemical profiling to develop a chemical fingerprint of Manuka Honey.



This fingerprint is now being utilised for the UMF™ grading system. To qualify for a UMF™ grading honey must contain DHA (dihydroxyacetone), Leptosperin, and Methylglyoxal. The current grading system utilises the quantity of Methylglyoxal present in the honey to provide the rating number.
