Jarrah honey and Manuka honey are both premium bioactive honeys, but they differ in origin, activity measurement, flavour profile, and nutritional composition. Jarrah honey from Western Australia uses the Total Activity (TA) rating system and typically delivers two to three times more antioxidants than equivalent Manuka honey, with a lower glycemic index and a rich, caramel-like flavour.
What Makes Jarrah Honey Different from Manuka?
Jarrah honey comes exclusively from the Jarrah tree (Eucalyptus marginata), native to the forests of Western Australia. These ancient trees flower only every two years, making Jarrah honey inherently rare. Manuka honey, by contrast, comes from the Leptospermum scoparium bush found across New Zealand and parts of eastern Australia.
The key distinction lies in how each honey's bioactivity is measured. Manuka uses the MGO (methylglyoxal) or UMF rating system, which focuses on a single antibacterial compound. Jarrah honey is rated using Total Activity (TA), which captures the full spectrum of antimicrobial activity — including hydrogen peroxide activity, which research suggests may offer broader bioactive potential.
TA vs MGO: Understanding the Rating Systems
Total Activity measures the overall antimicrobial strength of honey against a standard phenol solution. A TA30+ Jarrah honey, for example, demonstrates antimicrobial activity equivalent to a 30% phenol solution. This is a broad-spectrum measurement that captures multiple bioactive pathways.
MGO measures the concentration of a single compound — methylglyoxal — in milligrams per kilogram. While MGO is well-researched, it represents only one mechanism of antibacterial action. TA captures the complete picture, which is why many researchers and honey scientists consider it a more comprehensive measure of bioactivity.
Antioxidant Comparison
Research conducted by Pavy and Dragar (2011) for the WA Jarrah Honey Committee found that Jarrah honey may contain approximately two to three times more antioxidants than Manuka honey of comparable grade. Antioxidants play a role in supporting the body's natural defences against oxidative stress, and this higher concentration is one reason Jarrah honey has attracted increasing attention from health-conscious consumers.
Glycemic Index
Jarrah honey has a naturally lower glycemic index compared to most other honeys, including Manuka. This means it may cause a slower, more gradual rise in blood sugar levels. For people who are mindful of their sugar intake but still want to enjoy a natural sweetener, Jarrah honey offers a compelling option.
Flavour and Texture
Jarrah honey is known for its rich, dark colour and distinctive caramel-malt flavour with subtle nutty undertones. It has a smooth, thick consistency and does not crystallise easily — a natural property of its unique sugar composition. Manuka honey tends to be lighter in colour with a more medicinal, slightly bitter taste that some find an acquired preference.
Sustainability and Provenance
Western Australia remains one of the last places on earth free from the Varroa destructor mite, a parasite that has devastated bee populations globally. This means WA honey — including Jarrah — comes from some of the healthiest bee colonies in the world, foraging in pristine, ancient forests.
At Forest Fresh Honey, every batch of Jarrah honey is tested across five independent laboratories and comes with a Certificate of Analysis verifying its TA rating, ensuring you receive exactly what the label promises.
Which Should You Choose?
Both Jarrah and Manuka are premium honeys with genuine bioactive properties. If you prioritise broad-spectrum bioactivity, higher antioxidant content, a lower glycemic index, and a smoother flavour experience, Jarrah honey may be the better choice. If you are specifically seeking high-MGO honey for targeted use, Manuka has a well-established track record.
Many of our customers who previously bought Manuka have made the switch to Jarrah after comparing the science and the taste. The best way to decide is to try both — but we think Jarrah speaks for itself.

Frequently Asked Questions
Is Jarrah honey better than Manuka honey?
Both are premium bioactive honeys. Jarrah honey may offer broader antimicrobial activity (measured by TA), higher antioxidant levels, and a lower glycemic index compared to Manuka. The best choice depends on your personal health goals and taste preferences.
What does TA mean on Jarrah honey?
TA stands for Total Activity. It measures the overall antimicrobial strength of the honey against a phenol standard. A higher TA number indicates stronger bioactive properties. Forest Fresh Honey offers Jarrah from TA10+ to TA50+.
Does Jarrah honey crystallise?
Jarrah honey has a naturally high fructose-to-glucose ratio, which means it resists crystallisation much better than most honeys, including Manuka. It maintains its smooth, liquid consistency for years when stored correctly.
Where does Jarrah honey come from?
Jarrah honey comes exclusively from the Jarrah forests of Western Australia. The Jarrah tree is endemic to WA and flowers approximately every two years, making this honey naturally rare and seasonal.
Can I use Jarrah honey every day?
Yes. Many people incorporate a teaspoon of Jarrah honey into their daily wellness routine — in warm water, smoothies, on toast, or straight from the spoon. As with any honey, it should not be given to children under 12 months of age.
