Why Proper Storage is Important

Maple syrup is a natural product extracted from maple trees. It’s made by boiling down the sap of a maple tree and is often used as a sugar substitute.

This syrup contains no preservatives, so proper storage maintains the quality of maple or high fructose corn syrup. It also prevents the growth of bacteria, mold, and yeast, leading to a loss of flavor and even making the syrup unsafe to consume.

One of the most critical factors in storing maple syrup is temperature. Maple syrup should be stored in a cool, dark place, away from direct sunlight and heat sources.

The ideal temperature for storing even unopened maple syrup is between 32 and 40 degrees Fahrenheit. If the temperature is too high, the syrup will spoil quickly, losing its unique flavor and becoming thick or cloudy. In extreme cases, it ferments and becomes alcoholic.

You should check the container’s expiration date and store maple syrup no longer than 12 months after opening. After that time, the syrup may lose its flavor and consistency.

Shelf Life of Maple Syrup

The shelf life of pure maple syrup can vary depending on several factors. Some of them are the grade of the syrup, the storage conditions, and whether the container is opened.

Generally, unopened maple syrup can last several years, while opened containers will last up to a year if stored properly.

Temperature is a key factor in preserving syrups. It should be stored in a cool, dry place away from direct sunlight and heat sources.

You should also choose a suitable container for storing your maple syrup. Glass or food-grade plastic containers are ideal because they don’t react with the syrup. Moreover, they don’t affect its flavor or quality.

On the other hand, metal containers react with the syrup and create an off-taste.

Once opened, the syrup bottle should be stored in the refrigerator to keep it fresh for an extensive period. If you notice any mold or yeast growth, discoloration, or an off-taste, it’s best to discard it.

It’s worth noting that the grading system for maple syrup has recently changed, and the new system includes four grades based on color and flavor. While the grading system may have changed, the shelf life remains unchanged.

Best Containers for Storing Maple Syrup

To be more specific, these are the best containers for storing pancake syrups:

  • Glass containers are ideal for storing your maple syrup as they are non-reactive and won’t affect the flavor of the syrup.  They are also airtight and leak-proof, ensuring that it stays fresh. A glass container may include canning jars or an attractive glass jar.
  • Plastic bottles: These are a great alternative to glass bottles, as they are lightweight and shatterproof. However, choose a food-grade plastic bottle to avoid harmful chemicals from leaching into the syrup.
  • Mason jars: Mason jars are another great storage option. They are airtight, leak-proof, and come in various sizes, making them perfect for preserving small batches of syrup.

  1. Clean and Sterilize the Jars
    Before using the jars to store maple syrup, clean them thoroughly and sterilize them to avoid contamination.
    Wash the jars in hot soapy water, rinse well, and then sterilize them by boiling them in a pot of water for 10 minutes.
  2. Dry the jar
    After sterilizing your jar, remove it from the pot and dry it on a clean towel. Ensure the jar is completely dry before adding the syrup to prevent bacteria or mold growth.
  3. Fill the Jar With Hot Syrup
    Fill the jars with hot syrup to prevent the syrup from becoming contaminated. You can transfer the hot syrup directly from the pot or use a funnel.
  4. Leave Some Headspace
    When filling the jar with syrup, leave about 1/4 inch of headspace at the top to allow for expansion as the syrup cools.
  5. Wipe the Rims
    After filling the jars, wipe the rims with a clean, damp cloth to remove spills or drips. This will help ensure a tight seal and prevent bacteria or mold growth. You may or may not put the jar in hot water; it’s all about your preference.
  6. Store the Jars
    Once filled and wiped clean, screw on the lids tightly and store them in a cool, dry place away from direct sunlight.

Properly stored maple syrup can last up to a year, but it’s best to use it within six months for the best flavor.
