Short answer: Honey is a long-lasting food, but the best-before date still matters as a guide to quality. Store it sealed in a cool, dry place and discard it if contamination, an unusual odour or other clear signs of spoilage are present.
Best-before is about quality
In Australia, a best-before date indicates the period during which a properly stored food is expected to retain its quality. It is different from a use-by date, which relates to food safety and should not be exceeded.
Check the exact wording printed on your jar and follow any storage instructions supplied by the producer.
Natural changes do not always mean spoilage
Honey can darken, thicken or crystallise over time. These are common natural changes and do not, by themselves, show that the honey is unsafe. Gentle warming in warm water can return crystallised honey to a more liquid texture.
When to discard an opened jar
Water, food crumbs and dirty utensils can introduce contamination. Discard the honey if you see mould, notice fermentation or an unusual odour, or have another reason to believe the jar has been contaminated.
How to protect honey quality
- Keep the lid tightly closed
- Use a clean, dry spoon
- Store in a cool, dry cupboard away from direct sunlight
- Avoid repeatedly heating and cooling the jar
- Keep the batch and date information until the jar is finished
