I have found it hard in the past to remember when I opened a bottle and then I’m left wondering, does maple syrup go bad?

Do YOU have a jar (opened or unopened) just sitting there?

I’ll fill you in on some of the things I’ve learned over the years in the shelf life of pure maple syrup, so you’re never left wondering, does maple syrup go bad, ever again!

You may be wondering how to store pure maple syrup so that it lasts longer. This blog post will answer all of these questions and more!

Pure Maple Syrup versus Artificial Pancake Syrup

First, let’s look at a few of the differences between pure maple syrup and artificial pancake syrup.

maple syrup, does it go bad

Maple Syrup

Pure maple syrup is a liquid produced by the evaporation of water and left with maple sap to produce a sweet, thick liquid with a characteristic flavor. It’s taken from the sap of maple trees. For every 10 gallons of sap, you can produce 1 quart of maple syrup. Maple syrup does not have the typical artificial flavors which are often found in processed pancake syrup.

It does, however, contain lots of sugar. Not the kind that’s completely detrimental to your health. In fact, it’s pure sugar, but it does have some essential vitamins, like calcium, potassium, riboflavin and manganese!

Pure maple syrup does not have any added sugar (it’s all natural) and unlike a lot of other sweeteners can be a healthier choice for diabetics. According to diabetescare.net, it contains phytohormone and abscisic acid, both of which help control diabetes! Just make sure to count it toward your daily sugar count.

Artificial Pancake Syrup

Artificial pancake syrup is corn syrup or high fructose corn syrup with added sugars, artificial flavorings, and preservatives. The taste is significantly different to pure maple syrup and is also much cheaper to purchase!

There really aren’t any health benefits associated with the artificial syrup, other than the delicious taste.

But even though pure maple syrup is made from a natural source, it is still sugar and must be consumed appropriately!

How Long Can Maple Syrup Last?

This is where I’ll answer our question, does maple syrup go bad? The simple answer is, no. Maple Syrup can last indefinitely. Does it make a difference if it’s been opened or if it’s unopened? Yes, it can make a difference. But not as much as you think.

Technically, maple syrup does have an expiration date and it does go bad over time, in a that you’ll start to notice a growing mold. But not bad in the sense that you can’t still eat it. The actual shelf life of pure maple syrup is usually 12 months from the date that it was opened or bottled, but this does depend on storage conditions such as temperature and humidity levels in your home.

what happens if you eat expired maple syrup?

If you’ve been storing your pure maple syrup and the expiration date has come, does it mean that you need to throw it away? Absolutely not! You can totally consume expired map syrup. But please be aware of a few things before you do!

Pure maple syrup lacks the preservatives that artificial syrup does, but that doesn’t mean it won’t last! In fact, the high sugar content and low moisture environment help to prevent any bacteria growth.

Once maple syrup is opened and is exposed to air, a mold will eventually start to grow. This does not mean that the syrup will go bad and you should throw it away. It just means that there is some mold present in your maple syrup!

The thick consistency of the syrup does a good job at trapping air inside, so if you’ve noticed any signs of mold growing on top or around the bottom surfaces, don’t worry about using it as long as you’re careful to clean off anything sticking up out of the bottle before opening it up.

why is my maple syrup growing mold, Is it dangerous?

That’s the beauty of it! The mold that is found growing in maple syrup is non toxic. It’s called falsur mold and it is not allergenic, does not contain any toxins, nor does it cause harm to humans when consumed.

There’s a couple reason why mold will start to form.

  •  presence of light
  • high humidity
  • the presence of water droplets create the perfect biome for mold to grow

You’ll find that the artificial pancake syrups will not grow this mold. The additives and preservatives are probably more harmful to your health than this non toxic mold. Honestly, we should be concerned with why artificial foods don’t go bad over time!

But don’t go eating the mold just yet.

how to deal with the mold

  • skim off the fungus as much as you can
  • boil the syrup before eating it
  • eat and enjoy

The fact that mold can grown is what makes people think that maple syrup has an expiration date, but it can be enjoyed for much longer! The artificial syrup, while it will not grow mold, will eventually go bad because the taste deteriorates. This is mostly due to the artificial flavors added.

How to Store Maple Syrup

You’re probably wondering the best way and for how long you can store your precious stash of pure maple syrup for! A lot longer than you think! There are a few factors that affect how long you can store it such as storage conditions, humidity levels in your home or sealing it tightly in a container. Typically, you can keep it for up to 12 months before you’ll see signs of mold.

It’s important to note that processed pancake syrups, even though they have a longer shelf life, do not last nearly as long, taste wise, because they contain added artificial flavors which will break down sooner than natural sweeteners would. This also means that there are additives like preservatives used in these products which can make it seem like they have a longer lifespan.

Best way to store maple syrup

In order to prolong the growth of mold and fungus in maple syrup, it is best to store the pure version

  • in an airtight container
  • in a cool place
  • away from light

Poorly sealed jars of syrup are vulnerable to humidity and air which can give rise to fungal growth on its surface or moistness caused by condensation inside the jar.

ALSO! According to maplefarmers.com, for the best quality maple syrup, it’s best to use glass containers! Oxygen cannot get through glass, but it can permeate through plastic.
