About UMF™ 20+
UMF™ 20+ sits in our Signature collection, alongside UMF™ 22+. It's the grade our Mānuka Lovers Club members receive each month, with a rich, caramel character suited to a daily spoonful.
Flavour and how to enjoy it
Caramel, lush and smooth. Enjoy a spoonful on its own, or stir it through yoghurt, breakfast bowls or a cooled smoothie. Keep it away from hot drinks and hot food.
What UMF and MGO mean
UMF (Unique Mānuka Factor) is New Zealand's independent grading system for Mānuka honey. Each batch is tested for four naturally occurring markers: MGO, leptosperin, DHA and HMF. The higher the UMF number, the higher the MGO. UMF™ 20+ means a minimum of 830 mg/kg.

100% New Zealand monofloral Mānuka honey. Contains a minimum of 830 mg/kg naturally occurring methylglyoxal (MGO). Store in a cool, dry place out of direct sunlight. Not suitable for infants under 12 months.

What's the difference between UMF™ 20+ and UMF™ 22+?
UMF™ 22+ has a higher minimum MGO (1000 mg/kg against 830 mg/kg) and a bolder, more resinous flavour. UMF™ 20+ is the grade available through the Mānuka Lovers Club.
Why does high-grade Mānuka cost more?
Higher grades are rarer. Every jar is independently tested and certified, so the grade on the label is the grade in the jar.

Your questions, answered.
What people ask us most about UMF™ 20+, from how to enjoy it to how we prove the grade.
How do I enjoy UMF™ 20+ each day?
Take a spoonful on its own, as a quiet minute to yourself, or stir it through yoghurt, breakfast bowls or a cooled smoothie. A teaspoon a day is an easy place to start.
Can I have it on toast or in a drink?
Yes, as long as it stays under 40°C. Let your toast cool for a minute before you spread it, and stir it into drinks that are cool or at room temperature.
Does Mānuka have health benefits?
Mānuka has natural antibacterial, antioxidant and anti-inflammatory properties. MGO is the source of its special antibacterial properties and a key measure of potency, and UMF™ 20+ carries a minimum of 830 mg/kg. Enjoy it as a natural health food, as part of a healthy lifestyle.
How do I know it's genuine Mānuka?
Every batch is independently tested for four markers. Leptosperin comes only from Mānuka nectar and can't be made artificially, so it confirms authenticity. MGO confirms potency, DHA shelf life and HMF freshness. You can view the UMF™ 20+ certificate.
Why has my honey thickened or gone grainy?
Natural Mānuka can firm up or crystallise over time. That's normal, and your jar stays true to its UMF grade for its shelf life. Keep it in a cool, dry place, and don't heat it above 40°C to soften it.
How long does it keep?
Until the best-before date on your jar. Store it in a cool, dry place out of direct sunlight, with the lid on. A clean, dry spoon each time keeps it at its best.
Where does Rare's Mānuka come from?
Our beekeeping is run from Hawke's Bay, with hives across the North Island. In the Mānuka season our beekeepers travel long distances to get hives into position, then bring in every harvest themselves. Every jar is produced, packed and sealed in New Zealand.
