Maple syrup can be pricey, especially if you opt for high-quality Grade A syrup, so it’s important to ensure none goes to waste. If you’re curious about the shelf life of syrup and whether it ever spoils, you’re in the right place. We sought advice from experts on how to best store syrup and when it’s time to dispose of it.
### Does Maple Syrup Go Bad?
In short, pure maple syrup doesn’t expire, thanks to its high sugar content which inhibits bacteria growth. This is similar to honey, which also doesn’t spoil due to its sugary, low moisture content, as explained by Ben’s Sugar Shack in New Hampshire.
However, unlike honey, maple syrup can develop mold once opened. This occurs because the syrup is exposed to airborne mold spores.
### What To Do About Moldy Syrup
If your maple syrup has grown a thin layer of mold, perhaps due to being stored at room temperature, left out for too long, or forgotten in the fridge, don’t worry. Many people from syrup-producing areas simply remove the mold and continue to use it. While this practice might be safe, it isn’t officially recommended.
For safety, first remove the mold, then heat the syrup to at least 180°F to eliminate any remaining spores or bacteria. Next, strain it through cheesecloth into a clean container and refrigerate.
### Does Pancake Syrup Go Bad?
Pancake syrup, typically made from flavored corn syrup, differs from pure maple syrup. As noted by Karo, a manufacturer of corn and pancake syrups, its high sugar content ensures it doesn’t spoil and doesn’t require refrigeration. It’s generally resistant to mold, too.
### How To Store Syrup
According to the USDA, unopened maple syrup can last in your pantry for a year or more. Once opened, refrigerate it to prevent mold. Though syrup technically doesn’t spoil, mold risk increases over time.
For extended storage, freezing maple syrup is ideal. It won’t fully solidify and can be kept in the freezer indefinitely.
Pancake syrup doesn’t need refrigeration and can be stored in a closed container in the pantry once opened. Though best used within a year, it can last indefinitely.
