How Long Does Caviar Last? Unopened, Opened and Stored Well
Caviar is a delicate, perishable luxury, and its life is measured in days once the lid comes off. An unopened tin or jar keeps until the date printed on its label, provided it stays cold throughout. An opened tin is at its most radiant on the day it is served, remains pleasant for a short while after, and should not be kept beyond a few days in any circumstances. What follows explains the reasoning behind those windows, how to keep your caviar at its finest, and how to recognise when it has passed its peak.
TL;DR
- Unopened caviar should be kept refrigerated and eaten by the use-by or best-before date on the label, which is the only date that applies to your particular tin.
- Once opened, caviar is at its best the same day. Finish it within a day or two, and treat five days as an absolute ceiling, never a target.
- Keep it in the coldest part of the refrigerator, at 5°C or below, and return it there between servings.
- Sour, ammonia-like or sharply fishy aromas, slimy or collapsing eggs and cloudy liquid mean the caviar should be discarded.
- Freezing is not recommended, as it can damage the delicate texture of the roe.

The short answer: unopened and opened caviar
The honest answer depends on two things: whether the container is sealed, and how consistently it has stayed cold. A sealed tin held at the right temperature is governed by the date on its label. In Australia, that date has a precise legal meaning. The Food Standards Code defines a use-by date as the point after which food should not be eaten for health or safety reasons, provided the packaging is intact and the food has been stored under the stated conditions. Read that condition twice: the date is only as reliable as the storage behind it.
An opened tin follows different rules entirely. Once air meets the roe, the clock accelerates. Australian industry guidance on chilled, ready-to-eat seafood notes that these products remain vulnerable to Listeria growth even at refrigerator temperatures, and a desktop review prepared for the seafood industry recommends no more than five days for short-shelf-life ready-to-eat seafood. Caviar sits squarely in that family of products.
Five days is therefore the outer boundary of safety, not the measure of quality. The experience of caviar, its buttery smoothness, its clean, nutty richness and the gentle pop of each pearl, is at its zenith on the first day. America’s Test Kitchen observes that opened caviar may remain safe to eat after a day, yet it loses some of its nuance and softens in texture as time passes. Our own counsel to hosts is simple: open what you intend to serve, and enjoy it while it is still resplendent.
| Situation | What to expect | Practical guidance |
|---|---|---|
| Sealed tin, kept cold | Governed by the label date | Eat by the use-by or best-before date shown |
| Opened, same day | Peak flavour and texture | Serve well chilled and finish the tin |
| Opened, next day | Safe if kept cold, with some loss of nuance | Reseal tightly and return to the coldest shelf |
| Opened, several days | Texture softens and risk rises | Treat five days as an absolute ceiling |
| Left at room temperature | Quality and safety decline rapidly | Return to the refrigerator promptly |
Why caviar is so perishable
Caviar is, at heart, the cured roe of sturgeon: tender, high in natural oils, and lightly salted rather than preserved by heavy processing. That gentleness is precisely what makes it exquisite, and precisely what makes it vulnerable. The membranes of the eggs are delicate, the flavours volatile, and the salt content, kept modest so the roe may express itself, offers only limited protection.
The way a tin has been prepared also shapes its life. Some caviar is sold fresh and others gently heat-treated, and the distinction affects how long a sealed tin may rest in the refrigerator. If you are curious about the difference, our article on raw versus pasteurised caviar explains what each method means for flavour and keeping. In every case, the label on your tin states the date that applies to it, and the label always takes precedence over any general rule.
Keeping caviar cold: the temperature that matters
Temperature is the single most influential factor in how long caviar lasts. In Australia, food safety guidance from FSANZ treats potentially hazardous food as requiring temperature control at 5°C or colder, and the FSANZ temperature control guidance applies that requirement when food is received, stored, displayed and transported. It also advises following the manufacturer’s storage temperature wherever one is specified, which for caviar is frequently colder than a standard refrigerator setting.
A household refrigerator is not uniformly cold. The door shelves swing several degrees with every opening, while the back of the lowest shelf is usually the steadiest and coolest zone. That is where a tin belongs. A refrigerator thermometer, inexpensive and easily placed on the shelf, will tell you honestly whether your appliance holds 5°C or below.
We have written at length about the practicalities in storing caviar at home, including where to position the tin and what to avoid. For the table itself, our guide to serving caviar at the right temperature shows how to present the roe icy and luminous while staying within Australia’s 5°C rule.
Keeping caviar cold on the way to the table
The cold chain does not begin in your kitchen. Caviar bought online travels first, and the manner of its journey is part of its shelf life. Our piece on caviar shipping in Australia explains who is responsible for keeping it at 5°C in transit and what you should do on arrival. As a rule, unpack a delivery promptly, place it in the refrigerator, and never leave it on a verandah or in a warm hallway while you wait for a convenient moment.
When serving, the same principle holds. Bring the tin to the table nestled in a bed of crushed ice, and return it to the refrigerator as soon as the guests have had their fill. A tin left beside the champagne for an entire evening is a tin whose remaining contents are best discarded.
Once the tin is open
Opening a tin is the moment everything changes. Air contacts the surface of the roe, oils begin to oxidise, and any bacteria introduced by utensils or fingers find a hospitable environment. Opening it gently and cleanly therefore protects both flavour and safety, and our guide to opening a caviar tin in five careful steps walks hosts through the process.
If some caviar remains after the first service, the following measures preserve it best:
Smooth the surface gently with a clean, non-metallic spoon so no pockets of air remain, then press a small piece of cling film directly on to the roe before replacing the lid firmly. Return the tin immediately to the coldest part of the refrigerator, and use only clean, dry utensils each time you take a serving, since moisture and stray crumbs hasten decline. Plan to finish it within a day or two, in a simple presentation such as softly scrambled eggs, blinis or a spoonful of caviar with crème fraîche, rather than consigning it to the back of the shelf.
As for how caviar is best presented while it is open, the vessel makes a difference. Chilled mother-of-pearl, glass or horn spoons and a well-iced bowl keep the roe cool without imparting any metallic note. Our overview of caviar service vessels describes the options for hosts.
A note for those who are more vulnerable
Because ready-to-eat chilled seafood can support Listeria growth, people who are pregnant, elderly or immunocompromised should seek advice from their doctor or midwife before eating caviar or any chilled ready-to-eat seafood. This is a question of safe enjoyment, and a medical professional can advise on your circumstances.
How to tell if caviar has gone bad
Your senses are a useful guide, although they are never a guarantee. Some bacteria produce no obvious signs, which is why dates and temperatures matter more than any sniff test. That said, spoilage often announces itself, and the signs are consistent.
Begin with the aroma. Fine caviar smells clean and lightly oceanic, sometimes faintly buttery or nutty. A sour, vinegary, ammonia-like or sharply fishy odour is a clear signal to stop. Then examine the roe: glossy, distinct, individually defined eggs are what you want. Eggs that look mushy, collapsed or smeared together, a slimy film on the surface, or an unusual amount of cloudy liquid pooling in the tin all indicate decline. A small amount of natural brine is normal, a puddle is not.
Taste comes last and should never be used to resolve doubt. If anything about the aroma or appearance is wrong, discard the tin rather than tasting it. When a tin has been open beyond five days, or has spent a long evening at room temperature, discard it regardless of how it looks or smells.
Can caviar be frozen?
Freezing is generally discouraged. Ice crystals rupture the delicate membranes of the eggs, leaving them watery and soft on thawing, and the clean pop that defines great caviar is lost. If you have purchased more than you can serve, a better course is to share it: a small private tasting among friends or colleagues turns surplus into occasion. Choosing a size in keeping with the number of guests, rather than buying large and storing, is the most reliable way to enjoy caviar at its finest.
Different caviars, different considerations
Sturgeon caviar and the roe of salmon or trout differ in egg size, firmness and salt, and they are not interchangeable in their keeping qualities. Because of this, the printed date on each product is the authority, and general guides, including this one, should defer to it. When two tins of different species sit side by side in your refrigerator, read each label separately and eat the one with the earlier date first.
For the same reason, we would encourage you to think about quantity at the moment of purchase. A small tin, perhaps 30 grams for an intimate evening, will be finished in a single sitting, while a larger format suits a dinner party or a gathering where it will be shared the same day. Our caviar price guide for Australia offers further context on sizes and what to expect from different styles.
Our perspective
We regard caviar as the black gold of the table, and like any treasure it is best enjoyed at its zenith. Having curated rare and authentic caviar from prestigious producers, we believe the most generous thing a host can do is serve it at the right moment: properly cold, freshly opened and unhurried.
That conviction shapes how we advise our clients. We encourage choosing a tin sized to the occasion, so that the whole of it may be savoured on the day it is opened, and we encourage keeping it in the coldest part of the refrigerator until the very moment of service. The label on each tin carries the date that applies to it, and we ask that every customer treat it as the final word.
For events, we take this care a step further. When we host a private pairing of wine and caviar, the roe is brought to the table at the correct temperature and served in measured portions, so that nothing is wasted and every guest experiences it as the producer intended. It is a quiet discipline, yet it is the difference between a good evening and a memorable one.

Choose caviar to be enjoyed at its best
If you are planning an evening and wish to select caviar sized and styled for it, our caviar collection brings together curated tins from respected producers, alongside the spoons and accessories that complete the ritual. A 30 gram tin such as our 30G Baeri Signature Caviar suits an intimate occasion, while a 250G Oscietre Signature Caviar is made for a gathering where it will be shared in one sitting.
For hosts who would rather leave the details to specialists, we arrange private caviar and wine events for individuals and corporate guests, and our corporate and VIP gifting service offers a considered way to present fine produce to clients. If you would like to understand what an evening of this kind involves, our caviar tasting event cost guide sets out what to expect, and restaurateurs may find the caviar menu pricing guide helpful when planning service.
FAQ
How long is caviar good for in the fridge?
An unopened tin kept cold is good until the use-by or best-before date printed on its label. Once opened, aim to finish it within a day or two, as quality fades quickly, and treat five days as the outer limit for safety. Always keep it in the coldest part of the refrigerator at 5°C or below.
How long does caviar last after opening?
Opened caviar is at its finest on the day it is served and may remain safe a little longer if kept very cold and tightly covered. It gradually loses nuance and softens in texture, so we suggest finishing it within a day or two. Discard any that has been open beyond five days or left out of the refrigerator.
How do I keep caviar cold at a party?
Keep the tin in the refrigerator until guests are ready, then serve it nestled in crushed ice so it stays chilled throughout. Return it to the refrigerator once service is complete rather than leaving it on the table. Caviar that has sat at room temperature for an extended period is best discarded.
Can I freeze caviar to make it last longer?
Freezing is not recommended, because ice crystals damage the fragile eggs and leave them soft and watery once thawed. It is wiser to buy a quantity that suits your occasion and enjoy it within its date. If you have a surplus after opening, share it the same day.
What does bad caviar smell like?
Caviar that has turned smells sour, ammonia-like or sharply fishy, in contrast to the clean, lightly briny aroma of fresh roe. Mushy eggs, a slimy film or cloudy liquid are further warning signs. If you are in any doubt, discard it rather than tasting it.
