- How long does an unopened package of chocolate syrup last? The precise answer depends to a large extent on storage conditions -to maximize shelf life, store in a cool, dry area.
How long does an unopened package of chocolate syrup last at room temperature? Properly stored, an unopened package of chocolate syrup will generally stay at best quality for about 2 to 3 years.
Is unopened chocolate syrup safe to use after the expiration date on the package? Yes, provided it is properly stored and the package is undamaged - commercially packaged chocolate syrup will typically carry a Best By," "Best if Used By," Best Before, or "Best When Used By" date but this is not a safety date, it is the manufacturer's estimate of how long the chocolate syrup will remain at peak quality.
Storage time shown is for best quality only - after that, the chocolate syrup's texture, color or flavor may change, but in most cases, it will still be safe to consume if it has been stored properly, the package is undamaged, and there are no signs of spoilage (see below).
How can you tell if chocolate syrup is bad or spoiled? The best way is to smell and look at the chocolate syrup: if the syrup develops an off odor, flavor or appearance, or if mold appears, it should be discarded.
