Chocolate syrup is a great complement to many desserts and sweets. However, unless you are a frequent maker of ice cream sundaes, chocolate milk, or milkshakes, you might have difficulty using up an entire bottle of chocolate syrup before it goes bad.
You might have purchased that chocolate syrup for an ice cream sundae night many months (or even years) ago. The chocolate syrup has been at the back of your fridge for ages, and you may be questioning whether or not it has spoiled.
Here’s the lowdown. Fortunately, chocolate syrup is made and packaged in such a way that it has a long shelf life. If you are questioning the freshness of your chocolate syrup, read ahead.
How To Store Chocolate Syrup

If you have not yet opened the bottle of chocolate syrup, it can be stored at room temperature in a pantry or cupboard. Ensure it is not in a location where it will get too warm or exposed to direct sunlight. This can cause the syrup to lose its thick consistency.
Once the bottle of chocolate syrup has been opened, it should remain in the fridge for the rest of its shelf life. Many manufacturers recommend refrigerating after opening and will include this instruction on the packaging.
If you forget to place the chocolate syrup bottle back in the fridge, perhaps overnight, it will not spoil right away. If it has not been an excessive amount of time, put it back in the fridge, and it will likely be just fine.
Each time you use the bottle, ensure the lid is tightly closed afterward. This will make the syrup retain its rich taste and thick consistency for longer.
Shelf Life Of Chocolate Syrup

Fortunately, not much guessing has to occur when determining the freshness of chocolate syrup. Many brands will print a best-by-date on the packaging.
The time the bottle of syrup will be good largely depends on the brand, preservatives, and production, but most commercial brands produce chocolate syrups that will last for at least a year or two.
An unopened bottle of chocolate syrup can last for up to 2 years in a pantry or cupboard. An opened bottle can remain good for up to a year when refrigerated.
Freezing is an option if your chocolate syrup is about to expire and you want to preserve it for longer. To do this, you need to transfer the chocolate syrup into a container, release any excess air, and place it in your freezer.
Frozen syrup will need to thaw in your refrigerator and then heated afterward for best results. This method of freezing is not recommended unless necessary, as it will reduce the quality of the taste and texture.
What Happens When Chocolate Syrup Goes Bad?

Using expired chocolate syrup may not have any significant health consequences, though you may find the quality lacking. Chocolate syrup can lose its flavor and consistency when it goes beyond its expiration date.
Contaminants can get into a bottle of chocolate syrup, causing spoilage. If you are uncertain if a chocolate syrup has gone bad, pay attention to its smell, appearance, and texture.
Chocolate syrup that has gone bad can develop mold, and if this has occurred, it should certainly be thrown out. If the syrup has an odd smell, it has likely gone bad and should be disposed of.
Any noticeable changes in texture may indicate the chocolate syrup should not be consumed. This could include clumping, separation, or excessive thickness to its viscosity.
Even if the chocolate syrup is slightly past its expiration date, if it looks and smells normal, it is probably fine to consume. It may have just lost its rich flavor.
Homemade Chocolate Syrup

If your chocolate syrup has gone bad, but you don’t have time to run to the grocery store, mixing up a homemade batch is relatively simple and quick. The only ingredients you need are water, sugar, cocoa powder, salt, and vanilla, which are common ingredients in any pantry.
Homemade chocolate syrup will not have the preservatives that would commonly be included in a store-bought bottle, so it should be refrigerated and only kept for a month or so.
