How long does mustard last? Fridge, freezer & pantry
Unopened, mustard keeps in the fridge for 3 months. Once opened, use it within about 3 months for best quality and safety.
| Fridge | about 3 months |
|---|---|
| Freezer | Not recommended |
| Pantry (room temp) | Not recommended |
| After opening | about 3 months (refrigerated) |
Times are for unopened, properly stored mustard and reflect best quality. Always use your senses and follow any date on the package.
Signs mustard has gone bad
- Mould, separation that won't mix back, or a bulging lid.
- Off, sour, or fermented smell.
- Colour change or fizzing when opened.
When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.
Best way to store mustard
Many condiments are shelf-stable until opened, then need the fridge. Always check the label. Keep lids clean and tightly closed, and use a clean utensil so you don't introduce bacteria.
