Yes. Gravy mix lasts 2 years in the pantry. After that, or sooner if stored badly, it spoils: watch for the signs below.
How to tell if gravy mix is bad
Smell
Fermented, yeasty or sour beyond the product's usual tang.
Texture
Separation that does not stir back, or a slimy layer.
Colour
Darkening or a change in colour at the top of the jar.
Mould
Any fuzz on the surface or lid — discard the jar.
Gravy mix past the expiration date
Best-by and sell-by
FoodKeeper gives unopened gravy mix 2 years in the pantry or 1–2 days in the fridge, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
Past the date
Gravy mix past its best-by date is usually safe if stored well; check smell, look and taste before using.
How to keep gravy mix fresh longer
- Refrigeration time applies to prepared product.
- Refrigerate after opening unless the label says otherwise.
- Use a clean utensil each time; crumbs and double-dipping shorten shelf life.
