How long does corn syrup last?
Corn syrup keeps for about 3 years in the pantry. Counted from when you open or store it, unless the package says otherwise.

Keep tightly covered; refrigerate to extend storage life.
Storage times are the USDA FoodKeeper guidance for quality and safety, not a guarantee; a printed use-by date on the package comes first. Source: USDA FSIS FoodKeeper (CC0), fetched 2026-10-27, category Shelf Stable Foods.
How Known uses thisWhen a receipt lists corn syrup, Known estimates an expiry from the purchase date and typical shelf life and shows which rule it used, for example "7-day rule". Shelf-stable staples get no date at all.
