If you’ve experienced the pleasure of drizzling authentic maple syrup on your waffles or pancakes, then you surely recognize the delight of enjoying this flavorful, sticky, and sweet treat on your meals.

But did you know that maple syrup doesn’t actually go bad?

While maple syrup is an excellent addition to any breakfast, it can also be used in baking recipes and other cooking applications.

So, what exactly do we mean when we say “maple syrup goes bad?” And why would it matter if it does?

Does Maple Syrup Go Bad? 2

Does maple syrup go bad?

Maple syrup is an unrefined sugar product derived from the sap of maple trees.

It has a rich flavor and is high in natural sugars.

It is often referred to as Grade A maple syrup, which means it contains at least 51 percent of its total volume in simple sugars and has been boiled down to remove the water content.

Maple syrup can contain up to 90 percent sugar depending on where it comes from.

The key ingredient in maple syrup is the maple sap, which is collected by tapping maple trees.

The sap flows naturally from the tree into containers placed beneath the leaves.

When the sap begins to flow, it is called “sparkling.”

Once the sap stops flowing, it is collected and transferred to storage tanks for processing.

Once the sap is processed, it is filtered and boiled down to extract the sugar.

This process removes the water and produces a thick syrup.

Maple syrup is usually sold in glass bottles, but it can also be found in plastic jars and cans.

Because of the way it is produced, maple syrup has a shelf life of around six months.

However, this shelf life is dependent upon the quality of the raw materials and the manufacturing processes.

There are two main types of maple syrup: dark and light.

Dark maple syrup is darker in color than light maple syrup, which is lighter in color.

Darker varieties tend to have more complex flavors and richer aromas.

How long does maple syrup last?

When you purchase maple syrup, it should smell like maple syrup.

If it smells like anything else, don’t buy it!

Maple syrup will keep indefinitely if stored properly.

Store it in a cool, dark place away from heat and moisture.

To prevent mold growth, refrigerate it after opening.

How long does maple syrup last?

The short answer is: indefinitely! Maple syrup is considered a sugar syrup, which means it has the same shelf life as regular white sugar.

However, there are some factors that affect the shelf life of maple syrup.


When storing maple syrup, make sure to keep it away from heat sources and light.

This includes refrigeration, sunlight, and heat from appliances such as ovens, stoves, and microwaves.

In addition, store maple syrup in glass containers.

Glass is more resistant than plastic, so it will help protect against breakage and leaks.

You should also avoid using metal containers for storage, as they can cause the syrup to become discolored and opaque.

Finally, don’t pour maple syrup into plastic containers.

Plastic can react with the syrup and cause it to turn cloudy or even crystallize.


Keep your maple syrup at room temperature, between 50-60 degrees Fahrenheit (10-15 degrees Celsius).

If the room temperature gets too cold, the syrup may freeze.

If it gets too hot, the syrup could ferment or spoil.

It’s best to store maple syrup in the refrigerator, where it will stay cool.

It’s also important to keep the container tightly sealed, especially when refrigerating, to prevent evaporation.


As mentioned above, keep maple syrup away from heat sources like stoves and ovens, as well as direct sunlight.

When stored properly, maple syrup can last up to 30 years without spoiling.

Can you freeze maple syrup?

You might be wondering whether or not you can freeze maple syrup.

If you have some leftover maple syrup from the holidays that you’re trying to use up before it spoils, then you definitely should!

Maple syrup can be frozen for several months without losing its quality, making it perfect for last-minute holiday gifts.

The process of freezing maple syrup isn’t as straightforward as it is for honey or jam.

Unlike these other types of sweeteners, maple syrup contains water, which means you need to make sure that the syrup has been cooked down until all of the water evaporates (you don’t want to end up with ice crystals).

Once you’ve prepared your syrup, you will want to store it in the freezer.

The best way to keep it fresh is by using a vacuum sealer, which removes air and moisture from the jar.

Vacuum sealing prevents the growth of bacteria and the development of mold, while also preserving the taste of your syrup.

What is the best way to store maple syrup?

Maple syrup is considered a low-acid product due to its high sugar content.

This means that it is safe to keep at room temperature for up to three months.

However, once it reaches this point, it starts to lose some of its sweetness and become less viscous.

This is where the storage method comes into play.

The ideal way to store maple syrup is in a cool dark place away from direct sunlight.

A refrigerator is the best option as it will maintain the right temperature while keeping out most bacteria and mold spores.

It should also be stored in a tightly sealed container so there are no air pockets which can cause spoilage.

When storing maple syrup, it is important to avoid condensation.

This is caused by the difference in temperatures between the inside and outside of the container.

If the syrup is left too long without being refrigerated, the condensation can build up and cause the syrup to turn cloudy and unusable.

How can you tell if maple syrup has gone bad?

There are a few ways to check the quality of your maple syrup.

The most obvious way is by tasting it.

If it tastes off, then there is probably something wrong with it.

A more scientific approach is to use a refractometer to test the specific gravity (SG) of your maple syrup.

This will help you determine whether or not your syrup is still safe to consume.

However, these two methods aren’t perfect.

There are several factors that can affect the taste of your syrup, including temperature, storage conditions, and even the type of sap from which the syrup was extracted.

So, while they are useful tools for determining overall quality, they aren’t always 100% accurate.

Another thing to keep in mind is that maple syrup isn’t like other sweet syrups.

It contains complex sugars that are very hard to break down and digest.

So, if you have a maple syrup allergy, it may be best to steer clear of it altogether.

What does bad maple syrup taste like?

There are actually two types of maple syrup.

Raw sap, which is the liquid that comes out of the trees during springtime, is known as Grade B maple syrup.

It has a high sugar content (between 40-50 percent) and is considered the best type of maple syrup.

Once harvested, the sap is boiled down into a thick syrup that is then bottled.

This process removes most of the water from the sap, leaving just enough water for the syrup to flow through the pipes.

The result is Grade A maple syrup, which has a lower sugar content (between 30-40 percent).

It’s important to note that although Grade B maple syrup is more expensive than Grade A, there is no difference between the quality of the two.

Both are great options for cooking, baking, and enjoying on pancakes and waffles.

But what about those times when you don’t want to use either of these grades of maple syrup?

The next time you find yourself without any maple syrup, here are some tips for making your own.

1.Don’t throw it away!

You might think that if you have leftover maple syrup, you should just toss it out.

After all, it’s not going to go bad.

However, this isn’t true.

Maple syrup will spoil if it sits around for too long.

As mentioned above, Grade B maple syrup contains a higher percentage of sugar than Grade A.

When left to sit, the sugar will start to crystallize, causing the syrup to turn cloudy and unsightly.

This is why you should always keep a bottle of maple syrup in the fridge at all times.

If you’re planning on using it within a few days, you can leave it out on the countertop.

But if you’d prefer to keep it stored in the fridge, make sure to put it in a glass container so that it doesn’t touch anything else.

2.Make your own Grade A maple syrup

If you’re looking to save money, you might be wondering whether it’s possible to make your own Grade A maple syrup.

While this might seem like a daunting task, it’s actually very easy to do.

First, take a look at the ingredients list on the back of your jar of Grade A maple syrup.

You’ll see that it contains corn syrup, glucose, and molasses.

These three ingredients work together to create a syrup that is very similar to Grade B maple syrup.

To make your own Grade A maple syrup, combine 2 parts Grade B maple syrup with 1 part each of corn syrup, glucose, and molasses.

Once mixed, stir until the mixture becomes smooth.

Store your homemade syrup in a sealed glass jar in the refrigerator for up to six months.

To ensure that your syrup stays fresh, shake it every couple of weeks.

3.Try different flavors

Another option for creating your own Grade A maple syrup is to try adding fruits, herbs, spices, and even alcohol to the mix.

For example, if you’d like to add cinnamon to your syrup, simply add one teaspoon of ground cinnamon to a half cup of Grade B maple syrup.

As another option, you could try adding a splash of rum or bourbon to your syrup.

Simply heat the syrup in a saucepan on medium-low heat, stirring occasionally.

Once the syrup starts to bubble, add the alcohol and let it simmer for a minute before removing it from the heat.

Is it safe to eat expired maple syrup?

When you buy maple syrup from the grocery store, you are buying pure maple syrup.

Pure maple syrup contains no additives like corn syrup or molasses, which makes it much more flavorful than its counterparts.

Pure maple syrup has a shelf life of about two years, after which point it will start to lose some of its sweetness.

While most people don’t think about this, there is a significant amount of research into the shelf-life of different products.

In fact, according to The Food Lab, there are three main factors that determine the shelf-life of a product:

There are many ways to preserve foods for longer periods of time, including freezing, canning, and dehydrating.

Maple syrup is stored at room temperature, so it is safe to consume up to two years after purchase.

However, once the syrup has gone bad, it loses its effectiveness as a sweetener.

This means that even if you use expired maple syrup to make pancakes, you won’t get the same level of satisfaction.

In order to maintain quality, you should always use fresh maple syrup.

Many people wonder whether they should throw away their old maple syrup.

If you have purchased a large quantity, it might be tempting to save it for another use.

However, if you find that the syrup is no longer tasting good, then it’s best to discard it.

When storing maple syrup, it’s important to keep it cool.

If you leave it out on the counter, it will begin to ferment, which will cause it to become less tasty.

Refrigerating it will help prevent this.

The only way to ensure that your maple syrup will stay good is by using it within two years of purchase.

After that, you should throw it away, as it will no longer taste the same.

How long does maple syrup last after the expiration date?

Maple syrup has a shelf life and an expiration date.

It’s important to understand what those terms mean so you don’t waste money on a product that has spoiled.

The shelf life for maple syrup is between 3 months and 2 years.

The USDA says that a product is considered spoiled when it has lost its original taste and texture due to bacteria growth.

This means that the syrup will no longer be able to keep its consistency and sweetness as intended by the manufacturer.

Maple syrup that has gone bad will have a strong odor and will look cloudy, like watery milk.

The color of the syrup will change from clear to brownish-yellow and the taste will become bitter.

If you open a jar of maple syrup that has spoiled, it could be hazardous to consume.

In order to extend the shelf life of your maple syrup, you should store it properly.

Here are some tips to help you do this:

If you follow these guidelines, you will have plenty of maple syrup left in your fridge for many more years to come!

Is it okay to use maple syrup that has been frozen?

There are two main types of maple syrup available at grocery stores: Grade A and Grade B.

Grade A syrup is considered “raw” and contains no additives.

It comes from sap that is collected by tapping into trees.

The sap is boiled down until it turns into syrup.

Grade A syrup is usually thicker than Grade B syrup.

Grade B syrup is considered “processed” and contains artificial ingredients such as corn syrup, dextrose, and maltodextrin.

This type of syrup is often sold in containers that have a date printed on them.

If you see this date, it means that the product was processed within six months of its purchase date.

The FDA says that both grades of maple syrup are safe for consumption if they are stored properly.

In order to make sure that your maple syrup is safe to consume, follow these guidelines:

It’s important to note that there are some exceptions to these rules.
For example, if you plan on using your maple syrup in a cake recipe, then it should be stored in the fridge.

If you don’t plan on baking with your maple syrup right away, then it’s fine to leave it out at room temperature.

However, if you plan on using your maple syrup in a candy bar recipe, then you should keep it in the fridge.

If you plan on eating it right away, then you should use it within three days after opening it.
