Vinaigrette shelf life, answered
How long does vinaigrette last in the fridge?
4 weeks at 4°C (40°F) or colder (opened). Keep it sealed so it does not pick up moisture or odours.
How long does vinaigrette last in the freezer?
Not listed. FoodKeeper gives no freezer time for vinaigrette.
How long does vinaigrette last at room temperature?
It is not meant to be kept at room temperature. Refrigerate it.

6 months in the pantry, if the seal is intact and it is stored as the label says.
How long is vinaigrette good for past the expiration date?
FoodKeeper gives unopened vinaigrette 6 months in the pantry, 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.
How can you tell if vinaigrette is bad?
Fermented, yeasty or sour beyond the product's usual tang. Separation that does not stir back, or a slimy layer. Darkening or a change in colour at the top of the jar.
