Caviar past the expiration date
Unopened
FoodKeeper gives unopened caviar 1–4 weeks 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.

How to keep caviar fresh longer
