Those who grew up with syrup such as Aunt Jemima syrup probably stored that syrup just in the cupboard. What about if you have pure maple syrup? Maple syrup is a lot more expensive, so you probably want to store it the correct way to make it last as long as possible.
Pure maple syrup needs to be stored in the refrigerator. Pure maple syrup doesn’t have any preservatives in it, so if it is stored in the cupboard, bacteria or mold can form in your syrup.
How long will your pure maple syrup last in the refrigerator? It will last for about a year in the fridge, the lid sealed tightly. As with any food, you of course want to give it a quick sniff to make sure that nothing smells off about it, especially if it has been some time since you used it last.
