ELI5: In school we learnt that honey doesn't spoil. So how is it that packaged honey, even those that claim to be "pure", have an expiration date?

They don’t spoil but they do lose flavour, smell and water. If you store honey in fridge, some times you might notice it crystallises. This will happen in room temperature after a couple of years. So the expiration date is really a best by date.
