How Long Does Maple Syrup Last

Maple syrup is a delicious and versatile sweetener that is enjoyed all over the world. Whether you use it as a topping for pancakes or waffles or as an ingredient in baking and cooking, pure maple syrup is used in many households.

But have you ever wondered how long maple syrup lasts? While it may seem like a simple question, several factors can affect the shelf life of this sweetener.

This article will explore these factors and provide tips on storing maple syrup to ensure its quality and longevity.

Factors That Affect Maple Syrup’s Shelf Life

The first factor is the sugar content of the maple syrup. The syrup is made up of a concentrated solution of sugar and water, which makes it resistant to microbial growth. The higher the sugar content, the longer it will last.

Another factor that can affect the shelf life of maple syrup is temperature. You should store the syrup at a consistent temperature of around 40 degrees Fahrenheit. If the temperature fluctuates, it can cause the syrup to spoil more quickly.

The storage container that preserves maple syrup can also affect its shelf life. It is recommended to store the syrup in a glass or food-grade plastic container with a tight-fitting lid. This will help to prevent air and moisture from getting in, which can cause the syrup to spoil.

Finally, contamination can also affect the shelf life of the syrup. It is essential to use a clean utensil when scooping out maple syrup to prevent the introduction of bacteria or other contaminants.

Additionally, any debris or foreign substances in the syrup can cause it to spoil more quickly.

Compared to other syrups like corn syrup, maple syrup has a longer shelf life due to its high sugar content. Proper storage is critical to maintaining its quality and prolonging its shelf life.

If stored at a consistent temperature of around 40 degrees Fahrenheit, maple syrup can last up to a year in the refrigerator. It’s essential to store it in a clean, airtight container to prevent contamination and spoilage. Freeing maple syrup can extend its shelf life to up to a year without affecting its quality or flavor.

However, even with proper storage, keeping an eye on the syrup’s appearance, smell, and taste is important. Spoiled maple syrup can have a sour smell and taste and may appear cloudy or moldy. If you notice any of these signs, it’s best to discard the syrup.

Does Pure Maple Syrup Go Bad?

Yes, maple syrup can go bad if you don’t store it properly. When an opened maple syrup is left out for an extended period or stored in a container that is not airtight, it can become contaminated with bacteria and mold. This can cause the syrup to spoil and become unsafe to consume.

According to research, maple syrup is susceptible to mold growth, unlike honey. Storing it in the refrigerator is recommended once you open a container. When refrigerated, the syrup can last for six months to a year.

Storing any remaining maple syrup in an airtight container in the refrigerator is essential to prevent this. This will help to slow down the growth of bacteria and mold, which can prolong the storage life of the syrup.

It is also important to note that you should not confuse maple syrup with pancake syrup or pancake sauce. They’re typically made with corn syrup, artificial flavors, and other additives.

These syrups have a much longer shelf life than pure maple syrup but are not as healthy and natural as pure maple syrup.

Does Maple Syrup Need to Be Refrigerated?

You don’t need to refrigerate maple syrup but should store it properly to maintain its quality and freshness. You can store the syrup at room temperature in a cool, dry place away from direct sunlight.

Once opened, the syrup should be refrigerated to prevent spoilage and maintain its flavor. If you plan on storing the syrup for an extended period, it’s recommended to refrigerate it to ensure it stays fresh.

Additionally, it’s important to check the expiration date on the bottle and discard any syrup that has gone bad or developed mold.

How to Store Maple Syrup?

To store the syrup properly and prevent it from going bad, follow these tips:

  • Keep it in a cool, dry place: You should store maple syrup in a cool, dry place away from direct sunlight. Exposure to heat and light can cause the syrup to spoil more quickly.
  • Store it in a glass or plastic container: You should store maple syrup in a glass or plastic container with a tight-fitting lid to prevent air from getting in and causing spoilage. Avoid storing it in metal containers as they can react with the syrup and cause it to taste metallic.
  • Refrigerate after opening: You should refrigerate it to prevent spoilage. This will help maintain its quality and freshness.
  • Check for signs of spoilage: Maple syrup can go bad over time, and signs of spoilage include a cloudy appearance, mold growth, and off odors or flavors. If you notice any of these signs, discard the syrup immediately.

How to Tell if Maple Syrup Has Gone Bad?

There are a few signs to look out for to tell if the syrup has gone bad:

  • Cloudiness: If the syrup appears cloudy or has a thick, grainy texture, it may have started to ferment or spoil.
  • Mold: If you notice any mold growth on the surface of the syrup or around the container’s rim, the syrup has gone bad.
  • Off odor or taste: If the syrup smells or tastes sour or has an off flavor, it may have gone bad.
  • Color change: If the color of the syrup has significantly darkened or changed, it may indicate that it has gone bad.


If you’re a maple syrup fan, you might wonder how long this delicious liquid gold can last. The good news is that it can last for quite some time when stored properly.

So, whether you like to drizzle it over pancakes or add it to your favorite recipes, rest assured that your syrup will stay fresh and tasty.

Remember to keep your syrup in a cool, dry place, away from direct sunlight. Once you’ve cracked open that bottle, stick it in the fridge to keep it fresh for up to a year.

But watch for mold growth, cloudiness, or funky smells, as these could indicate your syrup has gone bad.

So go ahead and enjoy that syrupy goodness to your heart’s content. With some care and attention, your maple syrup will last as long as needed and will always be ready to add sweetness to your day.
