Caviar is one of the most perishable luxury foods you can buy, and improper storage is the fastest way to turn an expensive purchase into a disappointing one. The good news: storing it correctly is genuinely simple once you understand the two or three rules that actually matter.
Unopened Caviar: Longer Than You’d Expect
Properly processed, unopened caviar tins are more shelf-stable than most people assume, thanks to the salt-curing process used in production. Stored correctly:
- Unopened tins typically last 2–4 weeks in the coldest part of your refrigerator (never the door, where temperature fluctuates every time it’s opened)
- The ideal fridge temperature for caviar storage is between -2°C and 4°C — colder than most standard fridge settings, which is why placing it at the back of the bottom shelf, the coldest zone in most refrigerators, matters
- Never freeze caviar unless the tin is specifically labelled as freezer-safe by the producer — freezing ruptures the delicate egg membranes and destroys the signature “pop” texture entirely
Opened Caviar: A Much Shorter Window
Once opened, caviar’s clock starts ticking fast:
- Consume within 2–3 days maximum, stored tightly covered in the refrigerator
- Use a non-metal spoon and non-metal storage lid or plastic wrap directly on the surface to minimise air exposure
- Never leave an opened tin out at room temperature for more than 15–20 minutes at a time, even during active serving

Why the Storage Rules Are So Strict
Caviar’s high oil content makes it particularly vulnerable to oxidation once exposed to air — the same reaction responsible for the metal spoon rule discussed elsewhere. Oxidation dulls the flavour rapidly, turning a bright, briny, buttery taste flat and slightly bitter within days if storage conditions aren’t controlled.
| Storage Scenario | Shelf Life | Key Rule |
|---|---|---|
| Unopened, refrigerated | 2–4 weeks | Store at back of bottom shelf, -2°C to 4°C |
| Opened, refrigerated | 2–3 days | Cover tightly, minimise air exposure |
| Room temperature (serving) | 15–20 minutes max | Keep tin nested in ice throughout service |
| Frozen (unless labelled freezer-safe) | Not recommended | Ruptures egg membrane, ruins texture |
Chef’s Recommendation
If you’re buying caviar for a specific event, order it as close to the date as reasonably possible rather than weeks in advance — even within its shelf-stable window, flavour is at its absolute best in the first several days after you receive it. Treat “can last a few weeks” as a safety window, not a target for when to actually eat it.
“Caviar doesn’t spoil the way most food does — it fades. The flavour doesn’t turn dangerous, it just quietly loses everything that made it worth buying in the first place. Storage is how you protect that window.”
Signs Your Caviar Has Gone Past Its Best
Watch for a change from glossy to dull-looking pearls, any hint of an ammonia-like smell (distinct from the normal clean, briny scent), or a texture that’s lost its characteristic pop and turned mushy instead. Any of these signs mean it’s time to discard, regardless of the printed date.
Setting Up for a Longer Gathering
If you’re hosting an event where caviar service will run for a few hours, keep the tin nested in a bowl of ice throughout, replenishing the ice as it melts, and only spoon out small portions at a time rather than leaving the entire opened tin exposed to room air continuously.
The Bottom Line
Store unopened Meatigo caviar in the coldest part of your fridge, consume opened tins within 2–3 days, and never let it sit at room temperature longer than active serving requires. Get these three rules right, and every tin will taste exactly as intended.
