How to tell real honey from fake
Quick answer: at home, the water glass, thumb and tissue tests catch honey thinned with water, and the iodine test catches added starch. None of them proves honey is pure: only a lab test of the sugar profile can. Buy from sellers who can tell you where, when and by whom the honey was harvested.
Fake and diluted honey is one of the most common food complaints in Kenya. Some of it is honey stretched with water or sugar syrup, and some contains no honey at all. Here's what you can check at home, which popular tests don't work, and what really proves purity.
5 checks you can do at home
None of these is proof on its own, but together they catch most crude fakes. Do them at room temperature.
1. The water glass test
Drop a teaspoon of honey into a glass of room-temperature water without stirring. Real honey sinks and sits as a lump at the bottom, dissolving slowly. Honey thinned with water or syrup starts to spread out as it falls.
Good at spotting watered-down honey. Some thin, runny real honeys also spread a little.
2. The thumb test
Put a drop on your thumb. Real honey stays in a thick bead. Honey that spreads straight away may have water added.
Quick, but hot weather and some flower sources make real honey runnier.
3. The tissue test
Drop a little honey onto a paper towel or tissue. Real honey sits on top for a while. Diluted honey soaks in fast and leaves a wet ring.
Another check for added water. Most useful together with the water glass test.
4. The iodine test (for starch)
Mix a teaspoon of honey with a little water and add 2–3 drops of tincture of iodine from a chemist. If it turns blue or black, starch or flour has been added.
Reliable for starch only. It won't catch sugar syrups, which are the more common adulterant.
5. Watch it over the weeks
Most real honey slowly turns cloudy and solid, especially in cool weather. That's natural: see why honey crystallises. Honey that stays perfectly clear and runny for many months may have been heated or mixed with syrup.
A clue, not proof. Some real honeys, such as acacia, stay liquid for a long time.
Myths to ignore
The matchstick or flame test
Dipping a match in honey and lighting it tells you very little. All honey naturally contains some water, and the result depends mostly on how much honey is on the match.
"Ants won't eat real honey"
Ants love real honey too. This one is folklore.
"Real honey never goes solid"
Usually the opposite is true. Crystallising is a natural sign of raw honey.
"It says pure on the label"
Anyone can print "pure" or "natural". Look for the details below instead.
What actually proves honey is pure
- Lab analysis. Laboratories measure water content and the natural sugar profile, and test for markers of added cane or maize syrup. This is the only real proof.
- Traceability. A genuine seller can tell you where, when and by whom the honey was harvested. Ask.
- Label details. Look for the producer's name and address, a batch number, net weight and a best-before date, plus the KEBS mark on packaged honey.
- Price. Real honey costs real money to produce. Honey sold far below market price deserves a closer look.
