The Complete Guide to
New Zealand Mānuka Honey

Mānuka honey is a premium honey produced by bees that collect nectar from the flowers of the native New Zealand mānuka tree (Leptospermum scoparium). It is renowned for its rich flavour, distinctive character and the naturally occurring compound methylglyoxal (MGO), which sets genuine Mānuka honey apart from most other floral honeys.

The amount of naturally occurring MGO varies from one harvest to the next and is influenced by factors such as flowering conditions, seasonal weather and the location of the hives. Every batch of genuine Mānuka honey should be independently laboratory tested to verify its MGO content, giving you confidence that the rating displayed on the label accurately reflects the honey in the jar.

At Mt Lyford Honey, our bees forage naturally among native mānuka in the remote alpine landscapes of North Canterbury. Every harvest reflects the unique flowers, climate and environment of the season. Our Mānuka honey is cold extracted, never blended and never heat-treated, preserving the authentic flavour, aroma and character created by nature.

Whether you're discovering Mānuka honey for the first time or choosing a premium New Zealand producer, understanding where your honey comes from, how it is produced and how it is independently tested will help you buy with confidence.

MGO stands for methylglyoxal, a naturally occurring compound found in genuine New Zealand Mānuka honey. It is one of the key compounds that makes Mānuka honey unique and is measured to indicate the concentration naturally present in each batch.

Every batch of Mānuka honey is independently laboratory tested to measure its MGO content. The result is displayed as a number on the label, such as 100+ MGO, 200+ MGO or 500+ MGO. Simply put, the higher the MGO rating, the greater the concentration of naturally occurring methylglyoxal in the honey.

MGO develops naturally as Mānuka honey matures. Freshly harvested honey contains DHA (dihydroxyacetone), a naturally occurring compound from the nectar of the New Zealand mānuka flower. Over time, DHA gradually converts into MGO, giving each harvest its naturally developed MGO level.

At Mt Lyford Honey, we allow this natural conversion to occur over time rather than using controlled heat to accelerate the process. Every batch is independently laboratory tested before packing, ensuring the MGO rating displayed on the label accurately reflects the honey in your jar.

While MGO is an important measure of Mānuka honey, it is only part of the story. The quality of the floral source, the skill of the beekeeper, the unique alpine environment of North Canterbury and careful, minimal processing all contribute to the authentic flavour, aroma and character of every jar of Mt Lyford Mānuka Honey.

MGO and UMF are two recognised grading systems used for genuine New Zealand Mānuka honey, but they are not competing systems.

MGO (methylglyoxal) is a laboratory measurement of the naturally occurring methylglyoxal in Mānuka honey, while UMF (Unique Mānuka Factor) is a certification and grading programme administered by the UMF Honey Association. Both provide consumers with confidence that they are purchasing authentic New Zealand Mānuka honey.

The MGO content of every batch is independently laboratory tested and displayed as a number, such as 100+ MGO, 200+ MGO or 500+ MGO. The higher the MGO rating, the greater the concentration of naturally occurring methylglyoxal in the honey.

UMF is a trademarked certification programme available to licensed members. To display the UMF trademark, qualifying honey must meet the programme's recognised quality standards, including testing for naturally occurring compounds such as MGO, together with other recognised authenticity markers.

At Mt Lyford Honey, we choose to display independently laboratory tested MGO ratings because they provide a clear, transparent and easy-to-understand measurement of methylglyoxal content. Every batch of our Mānuka honey is independently laboratory tested before packing, ensuring the MGO rating displayed on the label accurately reflects the honey in your jar.

Whether you compare MGO or UMF, the most important consideration is choosing genuine New Zealand Mānuka honey from a trusted producer that provides independent laboratory testing, transparent provenance and a commitment to quality. Mt Lyford Honey is proudly FernMark licensed, reflecting our commitment to authentic New Zealand products.

Every jar is harvested from the remote alpine landscapes of North Canterbury, where it is cold extracted, never blended and never ultra heat-treated to preserve the natural flavour, aroma and character of each unique harvest.

The best MGO strength depends on your personal taste, preferences and how you plan to enjoy your Mānuka honey.

Every jar begins the same way—bees collecting nectar from the native New Zealand mānuka tree. The difference is the concentration of naturally occurring methylglyoxal (MGO), which is independently measured and verified for every batch.

As MGO levels increase, the flavour of Mānuka honey typically becomes richer, more robust and more complex, with stronger herbal notes and a more pronounced natural bitterness. Many people begin with a lower MGO honey before progressing to higher strengths as they develop a taste for its distinctive character.

100+ MGO – A smooth introduction to genuine New Zealand Mānuka honey with a mild, well-balanced flavour. Ideal for everyday enjoyment.

200+ MGO – A richer Mānuka flavour with a higher naturally occurring MGO content while remaining smooth and versatile.

300+ MGO – A premium Mānuka honey with a fuller flavour, greater complexity and a higher concentration of naturally occurring MGO.

400+ MGO – A robust Mānuka honey with a distinctive herbal character and higher naturally occurring MGO content.

500+ MGO – Our highest MGO grade, offering an intense, complex flavour with the strongest natural Mānuka character and one of the highest concentrations of naturally occurring MGO in our range.

Whichever MGO strength you choose, every jar of Mt Lyford Mānuka Honey is harvested from the remote alpine landscapes of North Canterbury, independently laboratory tested, cold extracted, never blended and never ultra heat-treated.

The right choice isn't simply the highest MGO—it's the one that best matches your palate, preferences and the way you enjoy Mānuka honey.

Yes. Controlled heating accelerates the natural conversion of DHA (dihydroxyacetone) into MGO (methylglyoxal) in Mānuka honey. DHA occurs naturally in the nectar of the New Zealand mānuka flower, and over time it gradually converts into MGO as the honey matures.

Many Mānuka honey producers temperature controlled heat for up to 24 months to speed up this natural conversion before laboratory testing or packing. This can increase MGO levels more quickly than allowing the honey to mature naturally.

At Mt Lyford Honey, we take a different approach. Rather than using heat to accelerate MGO development, we allow the natural conversion from DHA to MGO to occur over time. We believe this better reflects the genuine maturity, flavour and character of each harvest while remaining true to our philosophy of producing premium New Zealand Mānuka honey with minimal intervention.

While controlled warming can accelerate MGO development, heat may also influence other natural characteristics of honey. That's why our focus is on preserving the authentic qualities of every harvest rather than accelerating its natural development.

Every batch of Mt Lyford Mānuka Honey is independently laboratory tested to verify its naturally developed MGO content before packing, ensuring the MGO rating displayed on the label accurately reflects the honey in your jar.

When choosing Mānuka honey, look beyond the label. Independent laboratory testing, a verified MGO rating, genuine New Zealand origin and transparent production practices are all indicators of authentic, premium Mānuka honey. At Mt Lyford Honey, these principles are at the heart of every harvest, ensuring every jar reflects the purity of its floral source and the craftsmanship behind its production.

Genuine Mānuka honey has an exceptionally long shelf life when stored correctly. Although every jar carries a Best Before date, this relates to peak quality rather than food safety. Over time, your honey may naturally become firmer, develop fine crystals, darken slightly or develop a richer flavour. These are normal changes and do not mean the honey has gone bad.

Unlike many lighter floral honeys, raw Mānuka honey naturally develops a firmer texture as it ages. Depending on the MGO rating and storage conditions, it may eventually become very firm or even hard. This is a natural characteristic of authentic Mānuka honey and a sign that it has been minimally processed.

To enjoy your honey at its best, store it in a cool, dry place away from direct sunlight with the lid tightly sealed. Room temperature is ideal. Refrigeration is not recommended, as cooler temperatures may encourage the honey to crystallise more quickly.

At Mt Lyford Honey, every jar is carefully packed with minimal intervention to preserve the authentic flavour, aroma and character of each harvest, allowing you to enjoy a genuine taste of New Zealand's remote alpine landscapes.

Genuine New Zealand Mānuka honey is more expensive because it is naturally rare, can only be harvested during a short flowering season, and every batch must be independently laboratory tested to verify its authenticity and MGO content.

The native mānuka tree (Leptospermum scoparium) flowers for only a few weeks each year, and weather conditions during this brief period can have a significant impact on the harvest. Some seasons produce abundant honey, while others yield far less, making genuine Mānuka honey a naturally limited resource.
