Does maple syrup go bad?

Maple syrup doesn’t technically “go bad”, but it does develop a very distinct flavor and smell if it becomes rancid or fermented. This is most likely to occur in extreme heat or in the presence of bacteria. If this happens, you should discard the syrup and get a fresh batch.

Does maple syrup go rancid?

The simple answer is that maple syrup does not go rancid. Maple syrup is a natural product and does not contain any added preservatives so it does not last forever. If you do find some that is rancid, it can usually be salvaged by heating it gently in a pot for a few hours and then straining it. You may end up with a thinner syrup, but it will be safe to use. It can be saved for making sauce.

Can maple syrup go bad?

You’re not likely to find mold on maple syrup, even if it has been sitting out in humid conditions for a few weeks. If the syrup crystallizes, it’s not spoiled; it just needs to be warmed up and allowed to liquify again. Maple syrup that has developed a strong or unpleasant odor is rancid and should be thrown out.

Will maple syrup go bad?

Maple syrup will crystallize when stored at room temperature. Even at cooler temperatures, it will eventually crystallize. To prevent crystallization, store maple syrup in an opaque container in the refrigerator. Heat and light will cause crystallization, so avoid exposing your syrup to direct sunlight.

How long does maple syrup keep?

Because maple syrup is so acidic, it can last for several months if stored in a cool, dry place. To speed up the process, you can add a little vinegar. This will help the syrup crystallize, making it last even longer. If it becomes cloudy or separates, you can reheat it and it will return to a clear consistency. If it does crystallize, you can scrape it off and use it as granola topping.
