Honey Left Out Overnight: Is It Safe?
Written by Jordan Morley · Reviewed against FSA chilling & danger-zone guidance · Last updated 28 October 2026
Honey is fine left out indefinitely — it's one of the few foods that essentially never spoils at room temperature.
Why it's OK
Honey is very concentrated sugar with very little water, which is why bacteria can't grow in it. Unopened or opened, the cupboard is the right place. Crystallising is normal and harmless. The one real caution is for babies under 12 months, who shouldn't have honey at all (NHS), for reasons that have nothing to do with how it was stored.

Common questions
Does honey go off?
Not in any practical sense. Its low water content and acidity stop bacteria growing. It may crystallise, which is harmless; stand the jar in warm water to liquefy it.
Is there anything honey should be kept away from?
Water: moisture getting into the jar can lead to fermentation. Keep the lid on and use a clean, dry spoon.
Can babies eat honey?
No. The NHS advises not giving honey to babies under 12 months old because of the risk of infant botulism. That's about the baby, not about how the honey was stored.
What if my honey has gone cloudy?
That's normal crystallisation or pollen, and it is safe. Fizzing, a sour smell or a bubbling lid mean fermentation; bin it.
