Signs of Spoilage
Extremely rare for unopened syrup. Possible signs might include a compromised seal leading to mold growth, or very unusual crystallization that seems off.
How to Check
Visually inspect the container for any signs of damage or a broken seal. Check for any visible mold or unusual cloudiness if the container is clear. The syrup itself should be clear (unless it's a darker grade) and free of any particles.
Storage Tips
Store in a cool, dark place away from direct sunlight and heat to maintain optimal quality over time. Glass bottles are often preferred for long-term storage.

Signs of Spoilage
Mold growth (fuzzy patches, typically white, gray, green, or pink, often on the surface), off-odors (sour, fermented, musty, or alcoholic smell), cloudiness, or unusual discoloration.
How to Check
-
Visual Inspection: Carefully examine the surface of the syrup and the inside of the bottle/jar for any visible mold growth or fuzzy spots. Look for any cloudiness or changes in clarity.
-
Smell Test: Sniff the syrup for any off-putting, sour, fermented, or musty odors. Fresh maple syrup has a distinct, sweet aroma.
-
Texture/Clarity: While less common, extreme spoilage might show changes in texture (e.g., Sliminess near mold) or overall clarity.
Storage Tips
Always use a clean spoon or utensil when dispensing syrup to prevent introducing contaminants. Ensure the lid is tightly sealed after each use. If mold is present, it is generally recommended to discard the entire container, as mold spores can be present throughout the syrup even if only visible on the surface. While some sources suggest skimming and boiling, for safety and quality, discarding is the safest option for home use.
freezerIndefinitely
Signs of Spoilage
Maple syrup does not truly freeze solid due to its high sugar content but becomes very thick. Spoilage is virtually non-existent in the freezer. Any issues would likely be related to container integrity.
How to Check
Check the container for any cracks or leaks that could compromise the syrup's quality upon thawing. The syrup should still have its characteristic color and aroma once thawed.
Storage Tips
Maple syrup can be frozen to extend its shelf life almost indefinitely. Use freezer-safe containers, leaving a small amount of headspace to allow for slight expansion. Thaw in the refrigerator or at room temperature. This method is excellent for buying larger quantities or for very long-term storage.
