- How long does unopened grenadine last? The precise answer to the question depends to a large extent on storage conditions - store unopened bottles of grenadine in a cool, dark area.
To extend the shelf life of unopened grenadine, keep unopened grenadine away from direct sources of heat or light.
How long does unopened grenadine last at room temperature? Properly stored, unopened grenadine will generally stay at best quality for about 2 to 3 years when stored at room temperature, although it will usually remain safe to drink after that.
Is unopened grenadine safe to drink after the "expiration" date on the bottle? Yes, provided it is properly stored, the bottle is undamaged and there is no sign of spoilage (see below) - commercially packaged grenadine 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 unopened grenadine will remain at peak quality.
How to tell if grenadine is bad or spoiled? If grenadine develops an off odor, flavor or appearance, it should be discarded.
