What Is Molasses?

Molasses is a thick syrup that comes from pure sugar cane juice. The syrup tends to be a light or deep brown color with a distinct flavor typically used in baking, grilling, or cooking. 

The syrup is often added to marinades and sauces, offering a sweet taste that is high in potassium and magnesium. Molasses is often compared to honey in terms of taste. 

Now that we have briefly established what molasses is, let’s move on to see if molasses can go bad! 

Can Molasses Go Bad?

Yes, molasses can go bad. Molasses is sensitive to heat and humidity, so if they are not stored correctly, it can go bad quickly!

The syrup is highly hygroscopic, attracting and retaining moisture that can promote bacterial growth. 

Whether you have purchased light, dark, blackstrap, sulphured, or unsulphured molasses, it needs to be stored correctly to prolong its shelf life! Don’t worry, we have some guidance on that coming up below. 

Now we have established that molasses can go bad, you are sure to be wondering how long you have to enjoy your syrup.

Unopened, molasses can last for 10 years, provided it is stored correctly!

Once you have opened your molasses, you have anywhere from one to five years to enjoy it. How long it lasts will depend on how well you store it and if you seal it after each use.

We strongly recommend sealing your molasses correctly after every use! 

How To Tell If Molasses has Gone Bad

It can be tricky to tell if your molasses has gone bad. The flavor, taste, and texture can remain the same for years, leaving you unsure if the molasses has gone bad or not! 

The only way to tell is if there has been mold growth in the syrup. Thankfully, mold growth is pretty obvious to spot, so once you notice any signs of mold in the bottle or jar, discard it immediately. 

Also, if you notice any slight changes in the color or flavor of the molasses, it might have gone bad.

It can be hard to spot these slight changes, so be sure to pay close attention to how your molasses looked and tasted when you purchased it and monitor it closely.

If you are ever unsure, discard the molasses and purchase a new bottle. It is better to be safe than risk ingesting gone off molasses! 

How To Store Molasses

The best way to store molasses is to keep it in a dark and cool cupboard or pantry. You can also store molasses in the refrigerator once opened.

Keep the molasses in its original packaging and store it away from any heat or humidity. 

Provided you keep the temperature stable, the molasses can last for years!

When refrigerating molasses, the texture will thicken. Make sure you consider this before placing your open molasses in the refrigerator. It can be harder to pour as the bottle will be colder. 

Make sure you warm the molasses up before you use it. You can place the bottle in a container of warm water for a few minutes to help the syrup become more liquidy and easier to pour. 

Can You Freeze Molasses?

You can freeze molasses if you want to, but we don’t recommend it. Freezing your molasses can impact the texture of it, which nobody wants! 

You could also end up encouraging mold growth when you thaw your molasses, rendering it unsafe to eat! 

As your molasses can last for ten years in the pantry, it seems pointless to bother freezing it! Instead, follow the storage tips we suggested earlier to extend the shelf life of your molasses. 

If you do want to freeze your molasses, transfer it to a freezer safe container. Pour the molasses into the container, taking care not to fill it to the brim.

Cover the container with an airtight lid and write the date on it before putting it in the freezer. 

Defrost the molasses in your refrigerator and inspect the syrup for any signs of mold growth before you use it. 

Final Thoughts 

And there you have it! Provided you follow our storage suggestions, your molasses should last for ten years!

It can go bad, though, so be sure to keep it out of any heat and watch for mold growth before you use your molasses!
