How do you know you’re buying authentic Mānuka Honey?

7 ways to be sure you’re choosing genuine, high quality Mānuka Honey from New Zealand.

Authentic New Zealand Mānuka Honey is amazing stuff. Rich in nutrients, rich in taste and prized for its health-supporting properties, this ‘liquid gold’ is highly sought after around the world.

But how can you be sure whether it’s the genuine article, or not? These days, it can be tricky trying to decipher a myriad of scientific-sounding terms and numbers. Some brands have created their own grading systems, while others are independently measured using the ‘MGO’ or UMF quality mark – it sure is confusing!

On top of that, some honey producers claim their honey is authentic, even though it hasn’t been tested or verified – and there are a number of counterfeit products available too. It’s a problem that can leave a sour taste in the mouth for those seeking this sweet gift from nature.

Read on to learn the key methods used for testing the authenticity of genuine Mānuka Honey, and 7 ways to be sure you’re always getting the real deal.

Firstly, what is Mānuka Honey?

Mānuka Honey is a unique and very special honey that’s produced from the characteristic nectar from the sweet-smelling flower of New Zealand’s native Mānuka tree.

Containing amino acids, vitamins, antioxidants, minerals, proteins, carbohydrates, and bioactive compounds, Mānuka Honey is an amazing product that's at the forefront of natural health science. No other honey has the volume or complexity of natural components as New Zealand Mānuka Honey.

Thick and delicious, with a characteristic dark cream to dark brown colour, Mānuka Honey has long been sought after as an exceptional honey with a distinct, complex flavour and rich aroma that’s very different from ordinary honey.

New Zealand’s native Mānuka trees only bloom for 2 to 6 weeks per year – no wonder authentic Mānuka Honey is so precious!

What makes Mānuka Honey authentic?

There are seven ways to know for sure that your jar of Mānuka Honey is authentic, no matter where you buy it in the world (spoiler alert, Comvita Mānuka Honey ticks all of these boxes!). In a nutshell, they are:

1. It’s from New Zealand
2. It’s made from Mānuka flowers
3. It gets the MPI tick (Ministry of Primary Industries)
4. It contains four unique compounds
5. It carries the UMFTM quality mark
6. It’s independently verified and certified
7. It’s produced by a reputable, well established brand

Want to know more? Here are more details about these 7 points of authenticity and why they matter...

1. Authentic Mānuka Honey comes from New Zealand

The native Mānuka tree’s roots run deep in New Zealand’s history and culture. From food to traditional medicine, Māori found many uses for the leaves, bark and gum of the Mānuka tree.

In fact, Māori consider the Mānuka tree and a taonga (treasure) and that they are the kaitiaki (guardians, not just of the tree, but also the knowledge and traditions associated with it. To Māori, the use of the name Mānuka means that this precious treasure is being honoured and protected.

As such, New Zealand is the only country that can legitimately use the word ‘Mānuka’ with a macron above the ‘a’ (the authentic Māori spelling). It’s our belief that no other country has this connection to the Mānuka tree and the name Mānuka should only be used when these trees are grown in New Zealand.

2. Authentic Mānuka Honey comes from Mānuka flowers

For honey to be legally labelled as ‘Mānuka Honey’, it must be predominantly collected from the nectar of New Zealand Mānuka flowers (Leptospermum scoparium)1. Authentic Mānuka Honey is a ‘monofloral’ honey that contains unique and beneficial compounds, which are lab tested to determine its purity and potency.

Mānuka Honey can only be produced in areas abundant with native Mānuka blossoms, which is why our hives are located in some of the most remote, untouched parts of New Zealand – with some areas only accessible by helicopter or hike-in.

What’s more, Mānuka trees only bloom for a very short 2 to 6 weeks a year, which is why every drop of authentic Mānuka Honey is so rare – and so highly prized.


Note the macron above the ‘a’ on Comvita Mānuka Honey – a sign that it’s authentic, independently tested Mānuka Honey from New Zealand.

3. Authentic Mānuka Honey is verified by MPI standards

The Mānuka Honey industry is regulated by New Zealand’s Ministry for Primary Industries (MPI). This means that that all honey exported from New Zealand under the name ‘Mānuka Honey’ undergoes stringent testing, ensuring that it’s unadulterated and true to label – giving consumers confidence that they are getting the real thing.

MPI enforces a Scientific Regulatory Definition for exported Mānuka Honey based on chemical fingerprinting and pollen DNA marker analysis. 1 This definition requires minimum amounts of these specific phenolic compounds to be present in the honey:

• 2-methoxybenzoic acid
• 2’-methoxyacetophenone
• 3-phenyllactic acid
• 4-hydroxyphenyllactic acid
• along with a Mānuka pollen DNA marker.

These compounds are produced naturally in the nectar of Mānuka flowers and therefore naturally occur in Mānuka Honey. 2 All of Comvita’s exported and domestic Mānuka Honey meets these stringent MPI standards. This means that, no matter where you buy our products, you can be confident that you’re buying authentic Mānuka Honey from New Zealand .


The four important compounds that are a measure of the quality and authenticity of Mānuka Honey.

4. Authentic Mānuka Honey contains 4 unique compounds

As well as the compounds measured by MPI, Comvita scientists, and others, have pioneered the discovery of four other unique compounds, which are also used to authenticate Mānuka Honey’s purity and potency.

The UMF™ (Unique Mānuka Factor) number represents these four unique signature compounds (more about that later in this article):

Methylglyoxal (MGO)

MGO is the compound that’s principally responsible for Mānuka Honey's unique non-peroxide antibacterial activity (which is not present in other types of honey). There have been cases of adulteration where synthetically made MGO has been added into honey to make ‘fake’ Manuka Honey. In other words, measuring MGO alone is not a guarantee of the purity and quality of Mānuka Honey.(3,4,5)

DHA is a natural plant compound found in the nectar of Mānuka flowers. DHA converts to MGO over time in Mānuka Honey as it matures.

Leptosperin

Leptosperin is a unique natural plant compound found only in Mānuka Honey. It’s extremely difficult to make synthetically and is not commercially available. As this compound cannot be artificially added to Mānuka Honey, it is an excellent marker for authenticity.( 6,7,8)

Lepteridine™ 3,6,7-Trimethyllumazine

Discovered by Comvita scientists, this is a unique natural plant compound found only in Mānuka Honey. It’s extremely difficult to make synthetically and is not commercially available. Like Leptosperin, this compound can’t be artificially added to Mānuka Honey, so it’s another excellent marker for authenticity.(9,10,11)

Comvita is the only honey producer that tests for Lepteridine™ 3,6,7-Trimethyllumazine levels in Mānuka Honey – another sign that our honey is genuine, high quality Mānuka Honey.


Look for the UMFᵀᴹ quality mark on your jar of Mānuka Honey – it’s a sure sign of authenticity.

5. Authentic Mānuka Honey carries the UMFᵀᴹ mark

Only New Zealand Mānuka Honey brands licensed with the UMFHA can carry the Unique Mānuka Factor (UMF™) quality mark, the most comprehensive, independently certified and internationally recognized quality assurance system available. Known as the ‘gold standard’ in quality control, it provides independent assurance of Mānuka Honey’s potency, authenticity, purity, shelf life and freshness.

UMF certification is the only quality and rating system that independently certifies the presence and quality of the four key natural components that make New Zealand Mānuka Honey unique.

To carry the UMF™ quality mark, genuine UMF™ Mānuka Honey must comply with all five of the following criteria:
1. UMF™ is clearly stated on the front label
2. It is packed into jars and labelled in New Zealand
3. It is from a New Zealand company licensed by UMFHA to use the name UMF™
4. It has the UMF™ licensee's name on the front label
5. It has a rating of UMF™ 5+ or more

Remember, not all Mānuka Honey is UMF™ rated – only the brands which have been independently tested and verified by UMFHA – including New Zealand’s leading honey brand, Comvita Mānuka Honey .

6. Authentic Mānuka Honey is tested and verified

As the pioneers of authentic Mānuka Honey and with nearly 50 years of beekeeping science, knowledge and care, there's simply no other honey that’s as tested and trusted as Comvita honey.
