Storage chart
| Type | Fridge | Freezer |
|---|---|---|
| fresh, in jar | 1–4 weeks; 2 days (after opening) | Not recommended |
Fridge at 40°F (4°C) or colder, freezer at 0°F (−18°C). Freezer times are for best quality; food kept frozen stays safe indefinitely.
Keep it longer
Keep seafood in the coldest part of the fridge and use it quickly. Thaw frozen seafood in the fridge, not on the counter.
Common questions
How long does caviar last in the fridge?
1–4 weeks (2 days once opened) in the refrigerator at 40°F (4°C) or below, according to USDA FoodKeeper data.
Can you freeze caviar?
Freezing isn't recommended for caviar; the texture and quality suffer.
How can I tell if caviar has gone bad?
Throw it out if you see mold, a slimy texture, an off smell or an odd color. For anything perishable, go by the storage time rather than smell: bacteria that cause food poisoning don't usually change how food looks or smells.
