If well stored and with undamaged packaging, it can go for years without trouble. With bff products i generally go to groceries stores and look for a section dedicated to these products. They sell them cheaper and are completely safe. Good way to save money and fight food waste.
Do things that have a BBF date expire if you wait years?
As they said, generally no, they may just not taste as good.
For example - a pot of chilli powder probably will be fine after 5 years unopened in a cupboard, but probably won’t be as spicy as it used to be.
