ELI5: Why is honey resistant to bacteria and rot?
gpt
A couple reasons. 

First, it's low in water. Bees process the nectar they collect in flowers by extracting a whole lot of the water in it. This makes it thick - so bacteria and yeasts (more likely than rot) can't get through its viscous surface to get into it - and with very low available water (i.e it's dry enough to resist bacterial growth, even though it's a liquid). In fact, honey sucks the water out of bacteria rather than the opposite, killing them before they can really get started.

Second, bees actually add a few antibacterial chemicals into it that they produce when processing it. 

Fun bonus fact: You can water it way down and throw yeast into it to make a drink called mead.
