Factors to Consider When Storing Maple Syrup

Regarding maple syrup, several factors come into play to ensure that the syrup remains fresh and delicious for as long as possible.


Temperature is one of the most critical factors when preserving maple syrup. You should store pure maple syrup at a consistent temperature of around 33°F to 40°F (0.5°C to 4°C), which is the ideal range for preventing spoilage.

Keeping maple syrup at room temperature or above can lead to fermentation, mold growth, and quality degradation.


Real maple syrup should be kept away from direct sunlight or bright artificial light, which can cause a breakdown in flavor and color. Store your maple syrup in a dark place, like a pantry or cupboard, to maintain its quality.

Air Exposure

Exposure to air can cause the syrup to absorb unwanted flavors and odors, leading to spoilage. Always keep the syrup bottle tightly sealed when not in use to prevent air exposure.


Pure maple syrup should be kept away from moisture, which can lead to fermentation, mold growth, and a loss of quality.

It’s also important to note that corn syrup and high fructose corn syrup differ from pure maple syrup and should be stored differently. They should be kept in a cool, dry place and away from direct sunlight.

Different Methods of Storing Maple Syrup

There are several methods of storing maple syrup, each with advantages and disadvantages. Here are four different methods of storing maple syrup:

After opening the container, store pure maple syrup in the refrigerator to prevent spoilage. It’s important to note that refrigeration will not affect the quality or taste of maple syrup.


When adopting the freezing technique, pour the syrup into an airtight container and leave a little room at the top for expansion. When you’re ready to use the syrup, thaw it in the refrigerator, and it will be good as new.


Canning involves boiling maple syrup to a specific temperature and pouring it into sterilized jars, which are then sealed and stored in a cool, dark place.

When boiling maple sap with hot water, it’s important to ensure a sufficient liquid level (around 1.5 inches) to avoid scorching and damaging the pan. Properly canned maple syrup can last for years.


This involves using a vacuum-sealing machine to remove all the air from the container and create an airtight seal. This method helps to prevent spoilage and can extend the shelf life of maple syrup.

Step-By-Step Guide on How to Store Maple Syrup

Refrigeration Method

  1. Transfer the maple syrup into an airtight container or jar with a tight-fitting lid.
  2. Store the container in the refrigerator immediately after opening.
  3. Ensure that the temperature of the refrigerator is between 33°F to 40°F.
  4. Check the container periodically to make sure it is still tightly sealed.

Freezing Method

  1. Transfer the maple syrup into a freezer-safe container or freezer bag.
  2. Leave at least one inch of space at the top of the container or bag to allow for expansion during freezing.
  3. Label the container or bag with the date of freezing.
  4. Place the container or bag in the freezer.
  5. Place the container or bag in the refrigerator to thaw the maple syrup and allow it to thaw gradually.

Canning Method

  1. Sterilize canning jars, lids, and rings according to the manufacturer’s instructions.
  2. Transfer the maple syrup into the sterilized jars, leaving about 1/4 inch of headspace at the top.
  3. Wipe the rims of the jars clean with a damp cloth, then place the lids on the jars and tighten the rings.
  4. Process the jars in a boiling water bath for 10 minutes.
  5. Remove the jars from the water and let them cool. Once cooled, check the seals by pressing on the center of the lids. If the lids do not move, the jars are properly sealed.

Vacuum-sealing Method

  1. Transfer the maple syrup into a vacuum-sealed bag or container.
  2. Place the bag or container into a vacuum-sealing machine.
  3. Follow the instructions on the machine to vacuum-seal the bag or container.
  4. Label the bag or container with the date of sealing.
  5. Store the vacuum-sealed bag or container in the refrigerator or freezer.

That’s it! With these methods, you can store maple syrup properly and ensure its freshness and quality for longer.

How Long Does Maple Syrup Last?

The shelf life of maple syrup depends on the storage method used:

  • Refrigeration Method: If stored in the refrigerator, maple syrup can last for up to six months to one year, depending on the quality of the syrup and how well it is sealed.
  • Freezing Method: If stored in the freezer, maple syrup can last indefinitely. However, consuming it within one year is best to maintain its quality.
  • Canning Method: If canned correctly, maple syrup can last up to two years. Once opened, it should be stored in the refrigerator and consumed within six months to one year.
  • Vacuum-sealing Method: If vacuum-sealed and stored in the refrigerator or freezer, maple syrup can last up to one year.

It’s important to note that the quality of the maple syrup can deteriorate over time, even if it’s still safe to consume. You discard the syrup if it changes color, develops an off odor or taste, or has visible mold growth.

Long-Term Storage

Glass mason jars are airtight and prevent exposure to air and light, which can cause oxidation and spoilage. This helps preserve maple syrup’s quality and freshness for an extended period, typically up to two years.

Retains Quality and Flavor

Glass jars help maintain maple syrup’s natural flavor and quality without changing taste or texture. This ensures that the syrup tastes as fresh as it did on the day you canned it.

Non-reactive Material

Glass is a non-reactive material that does not react chemically with maple syrup. This ensures that the syrup’s natural taste and quality are preserved without contamination or harmful chemicals leaching into it.

Reusable and Eco-Friendly

Glass mason jars are reusable, which makes them an eco-friendly option for canning maple syrup. You can sterilize and use them repeatedly, making them a cost-effective option in the long run.

Convenient Storage and Usage

Glass mason jars are easy to label and store, which makes it easy to keep track of the contents of the jars. They are also easy to open and use, making it easy to pour maple syrup from the jar without any mess.

When Is Maple Syrup Ready to Be Stored?

Maple syrup is ready to be stored once filtered and the desired consistency has been reached. The ideal consistency of maple syrup for storage is typically a density of 66-67 degrees Brix, you can measure it using a hydrometer.

Once the maple syrup has reached the desired consistency, it should be immediately transferred to clean, sterilized glass jars. The jars should be filled to within 1/4 inch of the top and sealed with new, unused canning lids.

It’s important to note that maple syrup should only be stored once it has been properly processed through canning, vacuum sealing, refrigeration, or freezing. This ensures that it is safe to consume and maintains its quality for an extended period.

If the maple syrup is not stored properly or processed correctly, it can spoil, develop mold, or ferment, making it unsafe to consume.

Therefore, following the appropriate storage and processing methods is crucial to ensure that the maple syrup remains safe and enjoyable.


You can store maple syrup using different methods, including refrigeration, freezing, canning, or vacuum-sealing. Refrigeration can preserve syrup quality for six months to a year.

Freezing can retain its quality indefinitely, but consuming it within a year is best. Canning and vacuum-sealing effectively preserve maple syrup for up to two years and one year.

However, its quality can deteriorate over time, even if it remains safe to consume. Proper storage in sterilized glass jars is crucial to ensure freshness and prevent spoilage.

Following the right storage methods will enable you to enjoy maple syrup in various ways throughout the year.
