How Long Does Mustard Last?
Storing mustard is similar to storing mayonnaise; it should never be stored in direct sunlight, instead of in a cool, dry, and dark place. The best place to store the mustard is a kitchen or the pantry cabinet.
While applying the mustard, always use a clean spoon or a knife for application as any used spoon may transfer bacteria leading to premature spoilation of the mustard. Even if transferring the mustard to the other container or jar, try to clean it by rinsing it with water and then changing the pot.

Why Does Mustard Last 1 To 2 Year?
The mustard is an acidic compound and a consumable whose shelf life is excellent in every way. Being a food that is always consumed and brought in bulk, there is always a chance that the mustard can go wrong.
But preservation is the number one factor that keeps the mustard tight and ready to eat constantly.
As mentioned above, mustard contains a large amount of sodium or salt that enhances the taste and acts as the best preservation agent. As sodium is a base and mustard being an acidic compound, both neutralize each other’s reaction during production.
Often, store owners and households who buy mustard in bulk add vinegar in a specified proportion to the mustard reason being; vinegar is also a great form of preservative that is found in homes. The vinegar preserves the texture of the mustard prevents it from drying and even going stale or rotten.
Although preservation might play an important role, storage remains one factor. If the mustard is stored in moisture and hot condition, it can and will go wrong even before the expiry date; therefore, if stored in a cool and dry place, it preserves its taste and texture.
Moreover, if the mustard is stored in the cabinets or pantry, the mustard will last only 1 to 2 months after the expiry date. Still, if the mustard is stored in the refrigerator, it can last up to 1 to even two years after expiry as the fridge provides a perfect environment and keeps the mustard tight and fresh.
Conclusion
Mustard being a consumable stored and eaten in bulk, but expiry date and throwing away the mustard always remains a problem.
Mustard is one of those food items whose shelf life is never determined by the expiry date but only by how it was stored, as the preservations present in large quantities make the food fresh.
Expiry or best before is just an indication of the texture. After the expiry date, the surface becomes loose and flowy, fixed after adding vinegar, but the mustard can last up to a year even after the expiry and consumable in all kinds of forms.
