You know that moment when you finally crack open a tin of caviar?
It's like unwrapping a little gift from the sea. Those glossy pearls are just begging to be savored.
But here's the thing: all the care that went into raising those sturgeon and gently salting the roe stops right there at your kitchen counter.
Now it's on you to keep it from turning into a salty disappointment. When you get the storage wrong, you're basically throwing away a chunk of that luxury you splurged on.
But don't sweat it; once you know a few straightforward tricks, you'll stretch out the joy without any fuss.
Let's break it down so every bite stays as fresh as the first.
To keep opened caviar fresh, you must follow a few key rules. First, always keep it as cold as possible in the back of your refrigerator, ideally between 28-32°F.
Second, limit air exposure by pressing a piece of plastic wrap directly onto the surface of the remaining roe before sealing the lid.
Use a non-metallic spoon to serve, and aim to finish the caviar within 24 to 48 hours for the best flavor and texture.
Freezing is not recommended, as it will damage the delicate pearls and make them mushy.

Why Caviar Is So Perishable
So, why does that tin of caviar start to lose its edge right after you open it?
It's down to how it's made: just a light salting, called malossol, to bring out the roe's natural flavor without much else getting in the way.
That keeps things fresh and pure, but it also makes the eggs pretty vulnerable. They're high in moisture, like any fresh roe, and they don't take well to oxygen, small changes in temperature, or bacteria.
As soon as air hits them, oxidation sets in quickly, softening the texture and shifting the taste before long.
When sealed, it can last weeks; but when opened, you're looking at 24 to 48 hours max for the best quality, even if it's safe a bit longer.
The Golden Rule: Cold Is Key
The biggest thing with caviar storage is temperature. Hands down. For unopened tins, aim for 28 to 32 degrees Fahrenheit. It’s just above freezing to keep things stable without turning it solid.
Your average fridge runs a touch warmer, usually around 35 to 40, so stash it in the coldest spot: back of the bottom shelf, away from the door.
If you're really into this, some people set up a small dedicated fridge or even a wine cooler tuned to that sweet spot.
But once you pop the lid, you need to get it back into the cold right away. Air exposure starts messing with the roe almost immediately, breaking down that firm texture, and the chill is what buys you time by slowing everything down.
So, no lingering on the counter; straight to the fridge's chilliest corner after you serve.
Limiting Air Exposure
Next up: keeping air out of the picture, because once oxygen sneaks in, oxidation hits fast and turns things mushy or off.
The fix is quite simple. After you scoop out what you need, lay a piece of plastic wrap right over the top of the caviar, pressing it down gently so it hugs the surface. Ensure there are no gaps.
Then snap the lid back on tight. That little barrier cuts down on the air pocket and buys you those extra hours of quality.
If you're moving it to something else, skip plastic containers and go for a small glass jar with a screw-top lid. That’s because glass won't mess with the flavors like some plastics might, and it's easy to keep airtight.
You just give it a quick rinse with boiling water or run it through the dishwasher first to zap any bacteria. And if you've got leftovers from before, don't mix them in. Start fresh to avoid cross-contamination.
Timing: How Long Does It Last?
Opened caviar won't hang around indefinitely. It's just too delicate for that.
Most experts say to eat it up within 24 to 48 hours for the best shot at that pristine flavor and snap. Some types might stretch to three days if you're careful, but after that, the texture starts to soften and the taste fades fast, even if it's not spoiled yet.
That's why it's smart to think ahead about how much you'll actually serve. Grab a smaller tin so you can polish it off in one go and skip the waste.
Imperia Caviar has options in different sizes to match what you're planning, keeping everything fresh without leftovers staring you down.
Hygiene Matters
Hygiene is essential when it comes to keeping your caviar from going off track. When you skip it, bacteria or off-flavors can sneak in, cutting that freshness short.
Start with the spoon. Never reach for metal ones, since they react with the roe and can turn that clean, briny taste metallic or kick off oxidation right away.
You want to stick to mother-of-pearl, bone, or even a clean plastic one instead. Grab a fresh one for each serving to dodge any residue or spit from double-dipping.
When you're at the table, don't dump the whole tin out; just spoon out small portions as needed so the rest stays sealed and chill.
For bigger get-togethers, tuck the tin into a bowl of crushed ice to hold that steady cold without it warming up. And after that you can give those spoons a quick rinse in lukewarm water and let them air dry.
Freezing Caviar: A Controversial Option
Ever find yourself staring at a half-eaten tin of caviar, wondering if the freezer could save the day?
And that’s a fair question, especially if you've got more than you can handle in a couple days.
Technically, yeah, you can freeze it; portion it out into airtight containers or wrap it tight in plastic, then tuck it away at 0 degrees Fahrenheit or below.
But here's the catch: Those delicate eggs get mushy and lose their signature burst, thanks to the ice crystals disrupting the proteins that keep everything firm and glossy. Flavor holds up okay short-term, but after a month or so you lose.
Pasteurized caviar may hold up slightly better because it has already been heat-treated. But for fresh malossol varieties, freezing is not recommended if you want to maintain that pure, popping texture.
Save freezing for emergencies only, and when you thaw, do it slowly in the fridge to minimize the damage.
Most suppliers advise against it to preserve the quality, and if you do freeze, thaw slowly in the fridge to limit the changes.
Serving Practices That Preserve Freshness
How you bring that caviar to the table can make or break how long the rest of it stays good afterward. It's all about keeping the chill and the exposure short.
Skip any hot bowls or plates. They warm things up too quickly and start the breakdown. And don't let it sit out at room temp for over 20 to 30 minutes.
If it's part of a longer meal, like a fancy dinner, slot it in early so you can wrap up, seal the tin, and get it chilling again without delay.
Same goes for the sides. Hold off on mixing in crème fraîche or anything creamy until right when you're eating. Pre-mixing absorbs flavors and moisture, slashing that shelf life hard.
You can also chill your serving dish in the fridge for half an hour first to keep everything steady cold from the jump.
Why Imperia Caviar Simplifies Storage
One thing that makes dealing with our caviar a bit easier is how we've got the whole chain covered, from the second it leaves our hands to when you're spooning it out at home.
Start with shipping: everything goes out overnight, tucked into insulated boxes with gel ice packs that hold steady at 28 to 32 degrees Fahrenheit.
And to give you peace of mind, each package comes with a FreshTag temperature tracker, so you can check right away that it stayed cold all the way to your door.
For unopened tins at home, just slide them into the coldest corner of your fridge—back of the bottom shelf, away from the door where it doesn't fluctuate.
Most fridges hover around 36 degrees, so we suggest refreezing those gel packs from the box and nestling the tin right next to them for that extra chill.
That way, it stays good for one to three weeks, though for the absolute best flavor, aim to crack it open within the first week.
Once you do open it, finish within 48 hours to keep that texture and briny pop intact. For leftovers, press a sheet of plastic wrap straight onto the surface of the roe to block out air, then pop the lid back on tight.
We advise against freezing because the ice can rupture those delicate egg membranes, leaving you with something softer and less vibrant that just isn't the same. It’s better to plan your portions with our range of tin sizes so you don't end up in that spot.
