Yes, wine does go bad, but slowly, and most of it fades rather than spoils. An unopened bottle of everyday wine is usually at its best within one to three years, while an opened bottle lasts roughly one to seven days in the fridge depending on the style, or a few weeks for fortified wines such as Port.
A few wines are built to improve for decades, but they are the exception. Below: how long unopened wine lasts by style, how to tell if a bottle has turned, whether bad wine can hurt you, what label dates mean, and simple storage habits that keep wine at its best.
Does unopened wine go bad?
Unopened wine does not go off like milk, but it does change. Inside the bottle the wine slowly reacts with the little oxygen already there, so for most wines the fresh fruit fades, the colour deepens and the wine turns flat and tired.
The important thing to know is that the large majority of wine is made to be enjoyed young. Crisp whites, rosés, light reds and most supermarket bottles are at their best within a year or two of release, and keeping them longer rarely makes them better.
Only a small share of wines are built to age: ones with plenty of tannin (the grippy, drying feel in red wine), high acidity, concentrated fruit or sugar. A young Barolo or a fine Sauternes can improve for many years, because those parts develop rather than simply fade.
Rule of thumb: if you paid an everyday amount for it and it tastes good now, drink it within a year or two. Saving it for later is usually a gamble, not an investment.
How long does unopened wine last?
Typical drinking windows from release, for bottles stored well. Treat them as guides, not deadlines: wine kept somewhere warm fades faster, and bottles vary.
Style
Usually best within
Notes
Light, crisp white and rosé
1–3 years
Fresh fruit is the whole point, and it fades first
Ruby and tawny Port are ready to drink when bottled
Bag-in-box
Check the date on the box
The bag lets in a little air over time, so it is not for keeping
Not sure which row your bottle fits? The wine label usually gives the grape, region and vintage, which is enough to place it.
Does wine go bad after opening?
Yes, and much faster. Once air gets in, the wine oxidises and loses its fruit over a few days. Resealed and kept in the fridge, these are realistic timelines:
Opened wine
Keeps for, in the fridge
Sparkling
1–3 days with a sparkling stopper
Light white and rosé
5–7 days
Full-bodied white
3–5 days
Red
3–5 days
Fortified, such as Port
Up to about 3 weeks
Fino sherry is the exception among fortified wines and should be treated like a delicate white. For the reasons behind these numbers and tricks to stretch them, read our full guide on how long open wine lasts.
How to tell if wine has gone bad
Your nose is the best tool you have. Pour a little, look at it, smell it, then take a small sip. Most problems are obvious within seconds.
Sign
What it means
Safe? Pleasant?
Brown or amber colour, flat smell, nutty or sherry-like taste in a wine that is not sherry
Oxidised: too much air, too old or badly stored
Generally safe, not pleasant
Sharp vinegar smell, or a whiff of nail-polish remover
Volatile acidity: bacteria are turning the wine towards vinegar
Generally safe, unpleasant
Musty smell of wet cardboard, damp cellar or wet dog; fruit muted
Corked: a compound called TCA, usually from the cork
Harmless, but spoils the wine
Jammy, stewed or cooked fruit; cork pushed up or sticky wine around the neck
Heat damage: the bottle got too warm
Generally safe, usually dull
Unexpected bubbles or a prickle in a still wine, sometimes with a cloudy look
Refermentation: yeast has started working again in the bottle
Not dangerous, but the wine is faulty
Small clear crystals, or dark sediment in an older red
Tartrate crystals or natural sediment, not a fault
Safe, and the wine is usually fine
Bad wine usually tastes of less, not of something dramatic: flat, hollow or sour. Some things are normal, though. A light spritz is intended in some young whites, and old reds naturally turn brick-coloured at the rim. To recognise these smells with confidence, our guide to wine faults goes into each one in detail, and how to taste wine shows you a simple routine.
Can old or bad wine make you sick?
Spoiled wine is generally unpleasant rather than dangerous. Wine is acidic and contains alcohol, which makes it a poor home for the bacteria that make food unsafe, so a bottle past its best usually just gives a disappointing glass. Cork taint, oxidation and a vinegary edge are faults of taste and smell.
Common sense still applies. If a bottle shows mould inside the wine, looks strangely cloudy and smells wrong, or was stored somewhere you do not trust, pour it away. And whatever its age, wine is for adults of legal drinking age and best enjoyed in moderation.
Does wine have an expiry or best before date?
Usually not. In the EU, wine and other drinks with 10% alcohol or more do not need a best before date, and US labels do not require an expiry date for wine either. Some bag-in-box and canned wines carry one anyway; follow it.
The year on the front is the vintage, the year the grapes were picked, not an expiry date. It is still useful: subtract it from the current year and compare the result with the table above. A light white from five or six years ago is likely past its best, while a Barolo of the same age may only just be getting going.
What to do with wine that has turned
If the wine is merely a little tired, clean but lacking fruit, it is still fine for cooking: deglaze a pan, or add it to a stew, risotto or sauce. Leftover wine freezes well in an ice-cube tray, ready for the next recipe.
If the wine is vinegary, corked or tastes properly wrong, pour it away. Cooking concentrates flavours, so a musty or sour note ends up in your food. Many shops will exchange a corked bottle, so keep it and the receipt.
How to store wine so it lasts
Good storage means avoiding what ages wine too fast: heat, temperature swings, light and movement. You do not need a cellar.
Keep it cool and steady. Around 12–13°C is ideal. A steady temperature matters more than hitting the exact number, because repeated warming and cooling pushes the cork in and out. Our guide to wine storage temperature explains why.
Keep it dark. Light, especially sunlight, can damage wine, and clear bottles are the most at risk.
Keep it still. Not on top of the fridge or by the washing machine.
Lay corked bottles on their side. This keeps the cork in contact with the wine so it stays moist and seals well. Screw-capped bottles can stand up.
Avoid the kitchen. It is usually the warmest, most changeable room. A cupboard in a cool room, away from radiators, is better.
Screw caps are not a sign of cheap wine: they seal tightly, keep fresh styles fresh and cannot cause cork taint. Natural cork lets in a very little oxygen over time, and more if it dries out, which is why cork-sealed bottles are kept on their side. The kitchen fridge is fine for a few weeks, but too cold and dry for long-term keeping. Storage temperature is not the same as serving temperature: our serving temperature tool shows how cool to pour each style.
The short version: cool, dark, still, and on its side if it has a cork. Store it like that and drink everyday wines within a year or two, and very few bottles will ever go bad on you.
Wine does not expire like fresh food, and most bottles carry no expiry date. It does decline, though. Most everyday wine is best within one to three years of release, after which the fruit fades. A few wines, such as Barolo, vintage Port and top sweet wines, are made to improve for many years.
How long does unopened wine last?
Most unopened everyday wine is usually best within one to three years of release. Light whites, rosés and Prosecco are best young, fuller whites and everyday reds usually keep for two to five years, and age-worthy reds and sweet wines can last ten to twenty years or more. Cool, dark, steady storage helps any bottle keep longer.
How can you tell if wine is bad?
Look, smell and taste a small sip. Warning signs are a brown or amber colour in a young wine, a sharp vinegar or nail-polish smell, a musty wet-cardboard smell, cooked or stewed fruit flavours, a pushed-up cork, or unexpected bubbles in a still wine. Small crystals or sediment are normal and not a sign the wine is bad.
Does wine go bad after opening?
Yes, much faster than unopened wine. Once air gets in, the wine oxidises and loses its fruit. Resealed and kept in the fridge, sparkling wine lasts one to three days, light whites and rosés five to seven days, fuller whites and reds three to five days, and fortified wines such as Port up to about three weeks.
What does bad wine taste like?
Usually flat and stale rather than dramatic. Oxidised wine tastes hollow and nutty, like a cut apple left out. Wine turning to vinegar tastes sharp and sour. Corked wine tastes muted and musty, like wet cardboard. Heat-damaged wine tastes jammy and cooked. If a familiar wine suddenly tastes of very little, something has probably gone wrong.
Can old wine make you sick?
Old or spoiled wine is generally unpleasant rather than dangerous. Its acidity and alcohol make it a poor environment for the bacteria that make food unsafe, so a bottle past its best usually just tastes disappointing. Use common sense, though: if the wine shows mould, looks oddly cloudy and smells wrong, or has been stored somewhere doubtful, pour it away.
How long is wine good for?
It depends on whether it is open. Unopened, most everyday wine is good for one to three years, some reds for five and fine wines far longer. Opened, resealed and kept in the fridge, most wines last three to seven days, sparkling one to three days, and fortified wine a few weeks.
