How long does mustard last?
In the fridge, mustard keeps for 1 year after opening. In the pantry, it keeps for 1 to 2 years from the package date. Once opened, use it within 1 year. All 2 kinds are below.

By kind
| Kind | Pantry | Fridge | After opening | Freezer |
|---|---|---|---|---|
| Mustard | 1 to 2 years | no guideline | 1 year | no guideline |
| dried, ground | 6 months | no guideline | no guideline | 1 to 2 years |
No guideline: USDA gives no time for that place, usually because the food is not stored that way.
Does mustard go bad?
Yes. The fridge time above is the window USDA gives for good quality; after it, mustard may still be safe for a short while but quality drops and spoilage signs start. The date on the package is the maker's quality promise; the times here count from purchase unless marked "from the package date".
Two numbers to keep in mind: a fridge at 40 F (4 C) or below, and no more than 2 hours at room temperature (1 hour above 90 F / 32 C) for anything perishable.
How to tell mustard has gone bad
General signs for condiments, sauces & canned goods, the group USDA lists mustard under.
- Dented, bulging or rusted cans, especially at the seams
- Hissing sound or spray when a can or jar is opened
- Mould on the surface of a sauce or condiment
- Separation, discoloration or a sharp off smell from the jar
- Metallic taste or cloudy liquid in canned food
