How to choose Mānuka honey

Choosing Mānuka honey can feel confusing at first, especially when you see different strengths, terms like MGO and KFactor, and a wide range of prices. This guide is here to make things simpler.

We’ll explain what Mānuka honey is, why some jars cost more than others, what the different grading systems mean, and how to compare the options in our range. Whether you are completely new to Mānuka honey or just trying to decide between KFactor 16, MGO 400 or a more portable option like Snap Packs, this page will help you find the right place to start.

What is Mānuka honey?

Mānuka honey is a special type of honey produced in New Zealand. It is made by bees collecting nectar from the mānuka bush, which gives the honey its distinctive character and is one of the reasons it is graded differently from standard table honey.

When shopping for Mānuka honey, you will usually notice two things straight away: the strengths are shown differently, and the price can vary quite a lot from one jar to another. That is because genuine Mānuka honey is tested and graded, and higher strengths are generally rarer and graded at a higher level.

In our range, you will see Mānuka honey described using either MGO or KFactor. These are two different ways of helping customers understand and compare the honey, and we explain the difference in the next section.

Why are there different strengths of Mānuka honey?

When it comes to measuring the potency of Mānuka honey, there are two main rating systems: KFactor and MGO. Traditionally, Mānuka honey’s potency was measured using MGO levels. However, the New Zealand Government recognised the need for a more comprehensive rating system, leading to the development of the KFactor rating. Unlike MGO, KFactor considers multiple factors such as pollen count, purity, and live enzymes, providing a more accurate measure of effectiveness.

What is the difference between MGO and KFactor?

MGO and KFactor are both ways of describing Mānuka honey, but they do different jobs.

MGO measures the concentration of methylglyoxal in the honey. In simple terms, it gives you a fixed number showing how much methylglyoxal is present, which is one reason many customers find it easier to compare one jar with another.

KFactor is Wedderspoon’s own grading system. It was designed around a broader view of authentic Mānuka honey, in line with New Zealand’s scientific approach to defining it. It looks at four key chemical markers and the DNA of Mānuka pollen, rather than just one number. KFactor 12 means the honey meets or exceeds 65% Mānuka pollen, while KFactor 16 means it meets or exceeds 75% Mānuka pollen.

We still value that broader approach, but we also know that MGO has become a much more familiar comparison point for customers. That is why we increasingly use MGO to make the range easier to compare, while still maintaining the wider authenticity standards behind Wedderspoon honey.

Why is Mānuka honey more expensive?

One of the most common questions we hear is why Mānuka honey costs more than standard honey. The short answer is that genuine Mānuka honey is carefully sourced, tested, graded, and handled, rather than treated as a generic product.

Price differences usually come down to a few main factors. The first is strength, as higher graded Mānuka honey is rarer and more valuable. The second is size, with 500g jars naturally costing more than 250g jars. The third is the work involved in producing and bringing genuine Mānuka honey to market — from keeping hives in areas where Mānuka is the main flowering bush, to careful grading, independent testing, traceability, and shipping the honey from New Zealand to the UK.

How the honey is handled also matters. Wederspoon focuses on raw, unpasteurised honey that is gently processed to protect its natural character and consistency, rather than rushing it through heavier heat treatment. For us, authenticity matters, which is why we focus on Mānuka honey that is clearly graded, sourced and packed in New Zealand, and supported by traceability and certification paperwork.

How to tell if Mānuka honey is genuine

One of the biggest concerns people have when buying Mānuka honey is whether it is genuine. That concern is understandable, especially in a market where terms, strengths, and labels can feel confusing.

A good place to start is to look for clear grading, traceability, testing, and origin. Genuine New Zealand Mānuka honey for export must meet the New Zealand government’s scientific definition of Mānuka honey and be tested through recognised laboratory processes.

That is one reason we place so much value on trusted supply, clear certification, and full traceability. Our lead recommendation is Wedderspoon, which is sourced and packed in New Zealand, traceable from hive to home, raw and unpasteurised, free from antibiotics and glyphosate, Non-GMO Project Verified, FernMark certified, and independently lab tested.

For every batch of Wedderspoon Mānuka honey, we can provide traceability and certification paperwork on request. In a confusing market, those details matter. They help give customers more confidence that they are choosing genuine Mānuka honey, rather than relying only on front-of-pack wording.
