Opened corn syrup lasts for an indefinite period, although it's best to use it by the "Best by" date on the container.
Understanding Corn Syrup Shelf Life
It's a common question: how long does corn syrup last once opened? Luckily, corn syrup, particularly brands like Karo, has a very long shelf life.
Indefinite Shelf Life
- Opened or Unopened: According to Karo, their corn syrup is safe to consume for an indefinite period, whether the bottle has been opened or not.
- Best By Date: While it is safe to use indefinitely, Karo recommends consuming their syrup by the "Best by" date printed on the container to ensure the best quality.
- Refrigeration: Refrigerating opened corn syrup is optional. It will make the syrup thicker and pour more slowly.

Here's a quick overview of how to handle corn syrup:
Storage Tips
