Pure maple syrup doesn’t expire because of its high sugar content, but it can become moldy after opening. To prevent mold growth, you can store unopened maple syrup in a cool, dark location away from direct sunlight.

If your maple syrup becomes moldy, you can skim off the mold and heat the syrup to at least. Some say that even if it gets crystallized it is still very edible.
You can also store maple syrup in the freezer indefinitely.

To do this, you can fill a glass mason jar with syrup that is between 180 and 190°F, put on the lid, and tip it on its side for a minute to kill any bacteria on the lid.

Does Maple Syrup Go Bad?

Yes, maple syrup can go bad, although it has a longer shelf life compared to many other sweeteners. Mold is not uncommon in maple syrup, especially once opened.

The Massachusetts Maple Producers Association recommends refrigerating opened maple syrup to prevent spoilage. If harmless mold forms on the surface, the syrup can be brought to a slight boil, skimmed, and transferred to a clean container for refrigeration.

However, caution should be exercised when dealing with mold, as it is important to determine its type and safety before consuming.

How to Store Maple Syrup

When it comes to storing maple syrup, proper storage methods can help maintain its freshness and flavor. Here are some guidelines to ensure your maple syrup stays in top condition:

  1. Unopened maple syrup should be stored in a cool place, such as a pantry, away from direct sunlight. This helps maintain its quality until you’re ready to use it.
  2. Once opened, it is recommended to store maple syrup in the refrigerator to prevent spoilage. The cool temperature helps inhibit the growth of mold and other contaminants.
  3. If you plan on storing maple syrup for an extended period, you can also use the freezer. It’s important to note that maple syrup does not freeze solid but may become extremely thick. To thaw frozen syrup, simply bring it to room temperature or gently heat it in a warm water bath.
  4. When it comes to choosing a container for long-term storage, glass containers are preferred. They help retain the flavor of the syrup better than other materials.
  5. It’s important to note that sugar crystals may form in the syrup over time, but this is not a sign of spoilage. These crystals can be dissolved by reheating the syrup before use.

Maple Syrup Storage Tips and Shelf Life

Maple syrup is a delicious and versatile sweetener that can add a touch of sweetness to a variety of dishes. To ensure that your maple syrup stays fresh and flavorful for as long as possible, proper storage is key.

Here are some essential storage tips and information on the shelf life of maple syrup.

Storing Unopened Maple Syrup

When you have an unopened bottle or container of maple syrup, it’s important to keep it in a cool, dry place away from direct sunlight.

A pantry or cabinet is an ideal location for storing unopened maple syrup. This will help to maintain its quality and prevent any potential spoilage.

Storing Opened Maple Syrup

Once you’ve opened a bottle or container of maple syrup, it’s crucial to transfer it to the refrigerator or freezer. This will help prevent the growth of mold and extend the shelf life of the syrup.

Make sure to store the syrup in a sealed container to maintain its freshness and prevent any odors from permeating the syrup.

Storage Method Shelf Life
Refrigerator Up to 2 years
Freezer Indefinite

When stored in the refrigerator, maple syrup can typically last for up to 2 years, while the freezer allows for indefinite storage. This means that you can enjoy your favorite maple syrup for years to come.

Tips for Proper Storage

When handling maple syrup, it’s important to use clean utensils to avoid introducing any mold spores. Additionally, be mindful of the container and surroundings in which the syrup is stored, as this can impact its flavor over time.

Using glass containers for long-term storage is recommended, as they retain the flavor of the syrup better than other materials.

It’s also worth noting that while maple syrup does not technically expire, its flavor can be affected by prolonged storage or exposure to unfavorable conditions. To ensure optimal flavor, it’s best to use your maple syrup within a reasonable time frame.


In conclusion, proper storage is essential for extending the shelf life of maple syrup. When stored correctly, maple syrup can last up to a year in the refrigerator and indefinitely in the freezer, making it a versatile pantry staple. However, it’s important to note that these storage guidelines apply to 100 percent pure maple syrup, not pancake syrups that contain corn syrup and maple flavoring.

Mold can be a common issue once the syrup is opened, but it can be managed effectively. By bringing the syrup to a gentle boil, skimming off any harmless mold that forms on the surface, and transferring the syrup to a clean container, it can be safely enjoyed. It is also advisable to store the syrup in sealed containers and use clean utensils to prevent the introduction of mold spores.
