- How long does an unopened package of instant coffee 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 instant coffee last at room temperature? Properly stored, an unopened package of instant coffee will generally stay at best quality for about 12 to 18 months at room temperature.
Storage time shown is for best quality only - after that, the instant coffee's texture, color or flavor may change, but in most cases, it will still be safe to consume if it has been stored properly and the package is undamaged.
Is unopened instant coffee safe to use after the "expiration" date on the package? Yes, if properly stored - commercially packaged coffee will typically carry a "Best By," "Best if Used By," "Best Before", or "Use By" date but this is not a safety date, it is the manufacturer's estimate of how long the instant coffee will remain at peak quality.
How can you tell if instant coffee is bad or spoiled? Instant coffee typically loses flavor over time and develops a stale taste - if coffee develops an off odor, flavor or appearance, it should be discarded for quality purposes; if mold appears, discard the instant coffee.
