Manuka honey grades – UMF, MGO, KFactor

UMF Label

There are many grades of manuka honey. Manuka honey was first graded by the Unique Manuka Factor (UMF) Honey Association to determine the quality of the manuka honey sold by participating producers. To obtain a UMF number, the producer must have its honey tested by the association before it is allowed to label its UMF grade on every bottle of  honey. The yellow and black UMF label looks like this:

Non-UMF Labels

As the demand for manuka honey rises, the prices of UMF-graded manuka honey also escalates. This prompted certain reputable honey producers to start in-house honey quality checks and gradings, thereby doing away with the expensive cost of licensing the UMF trademark. Cost savings are then passed on to consumers.

Being reputable honey producers, they are able to guarantee the purity and quality of their manuka honey, and consumers are assured that they will be getting the same quality of honey at a cheaper price. Hence, the demand for non-UMF graded manuka honey have also increased.

UMF to MGO Calculator

UMF and MGO are two major standards for grading the quality of manuka honey. Research and studies have shown that manuka honey has antibacterial benefits due to the ingredient called methylglyoxal (MGO) that exists naturally in the honey. Generally, the higher the methylglyoxal content of the honey, the higher will be the UMF or MGO rating. Here is a guide on how to convert or compare UMF and MGO ratings.
