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.

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.
