How long does an unopened bottle of tartar sauce last at room temperature? Properly stored, an unopened bottle of tartar sauce will generally stay at best quality for about 12 to 18 months, although it will usually remain safe to use after that.

Is unopened tartar sauce safe to use after the "expiration date" on the bottle? Yes, provided it is properly stored and the bottle is undamaged - commercially packaged tartar sauce 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 tartar sauce will remain at peak quality.

Storage time shown is for best quality only - after that, the tartar sauce'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 bottle is undamaged, and there are no signs of spoilage (see below).

How can you tell if tartar sauce is bad or spoiled? The best way is to smell and look at the tartar sauce: if the tartar sauce develops an off odor, flavor or appearance, or if mold appears, it should be discarded.
