I believe they have recovered honey from Egyptian tombs that was thousands of years old and still edible. From recollection the syrup is too viscous for bacteria to colonise.
Fun fact: If you collect mad honey (the term for honey contaminated by bees which have pollinated poisonous flowers), you can wait for the poison to expire.
I’m impressed in a way that anything could be good up to twelve years past the expiration date.
Dry and sealed, it can last decades. Honey can last centuries but will usually expire after 1 year for legal reasons.
