How long does bee honey last in a jar?

In a sealed jar honey will last indefinitely. Honey has been found in Egyptian tombs which was 2,000 to 3,000 years old and still in good condition.

Honey that has been kept for some time tends to go cloudy and thicken. The honey is not 'going off', this is a perfectly normal process where the sugars are starting to crystalize out of solution. You can restore the honey to its original condition by gently warming the jar in a bowl of hot water. Be careful not to overheat the honey because that will spoil it.
