How Long Does Wine Last After Opening?

Once opened, most red and white wine stays enjoyable for three to five days if you recork it and keep it in the fridge. Sparkling lasts one to three days with a stopper, light whites and rosés closer to a week, and fortified wines like Port for weeks. The single thing that decides it is how much air the wine meets.

The short answer, by type

Here is the quick reference most people are looking for. These ranges assume you recorked the bottle and stored it upright in the refrigerator, which slows things down considerably.

Wine type	Days after opening (recorked, in the fridge)
Sparkling (Champagne, Prosecco, Cava)	1–3 days, with a stopper
Light white and rosé	5–7 days
Full-bodied or oaked white	3–5 days
Light red (Pinot Noir, Gamay)	2–4 days
Bold, tannic red (Cabernet, Syrah)	3–6 days
Fortified (Port, Sherry, Madeira)	1–4 weeks (Madeira: months)
Boxed wine (bag-in-box)	3–6 weeks

Treat these as guidelines, not expiry dates. A wine does not flip from perfect to undrinkable overnight; it fades gradually, losing its brightest fruit first and growing flatter and more sour over time. The numbers above are roughly when most people stop enjoying each style, not when it becomes a problem. If you only remember one figure, make it the three-to-five-day window for everyday reds and whites, which covers the large majority of bottles people actually open at home.

The one thing that actually matters: oxygen

Every number in that table comes down to a single process. The moment you pull the cork, the wine starts reacting with air, and oxygen slowly turns the fresh, fruity compounds into dull and eventually vinegary ones. A little air can help a young wine open up in the glass, which is the whole point of decanting, but over hours and days that same air is what wears the wine out.

This is why all the standard advice works the way it does. Cold slows the chemistry, so the fridge buys you time. Less air contact slows it too, so a tightly recorked, nearly full bottle lasts longer than a half-empty one left open. Once you understand that oxygen is the clock, every preservation trick makes intuitive sense instead of being a rule to memorize.

It also explains the most surprising number in the table: an already-oxidized wine like Madeira barely changes after opening, because the air has nothing left to do. The damage that ruins other wines is the entire flavor of that one.

There is a practical corollary worth knowing. The more wine you have already poured, the faster what remains declines, because a nearly empty bottle is mostly air. This is why the last glass from a bottle you opened three days ago can taste noticeably tired while a freshly opened, full bottle of the same wine tastes vivid. The wine did not change character; it simply spent more of its life surrounded by oxygen.

Why some wines last longer than others

If oxygen is the enemy, then a wine’s natural defenses are whatever slows oxidation down. Four things in particular act like built-in preservatives, and they are exactly the structural traits that describe how a wine tastes.

Acidity. High-acid wines resist oxidation longest. A zippy Riesling or Sauvignon Blanc holds its freshness for days, which is why crisp whites often outlast richer ones.
Tannin. In reds, tannin is a buffer. It reacts with oxygen first and shields the fruit, so a grippy Cabernet lasts longer open than a silky, low-tannin Pinot Noir.
Sugar. Sweet and off-dry wines keep longer, since sugar helps stabilize them. A dessert wine can be good a week or more after opening.
Alcohol. Fortified wines like Port and Sherry have had grape spirit added, pushing alcohol high enough to act as a preservative, which is why they last for weeks rather than days.

If those words, acidity and tannin and body, feel fuzzy, our plain-English wine glossary breaks each one down. The short version is that the same structure you taste in a wine is what predicts how it will age once the bottle is open.

How to tell if an open bottle has gone off

You don’t need a chart to know when a wine is past it; your nose and eyes will tell you. Look and smell for these signs before you pour a full glass.

It smells sharp or vinegary. A whiff of vinegar or nail polish means the wine has oxidized too far. This is the clearest tell.
It smells nutty, flat, or like sherry when it should not. Stale, cooked, or bruised-apple aromas signal a wine that has tired out.
The color has shifted. A white that has deepened to brownish gold, or a red gone brick-brown and dull, has seen too much air.
It tastes flat or sour. The fruit has faded and what is left is thin and tart, with none of the lift it had on the first night.

None of this is dangerous, just disappointing. Which brings up the question everyone quietly wonders about.

Will old open wine make you sick?

No. This is the reassuring part: wine does not spoil into something harmful the way dairy or meat does. Its acidity and alcohol make it a hostile place for the bacteria that cause food poisoning. An open bottle that has gone too far will taste unpleasant, sour, or flat, but drinking a glass of it is a matter of taste, not safety.

The worst realistic outcome is that a wine turns slowly toward vinegar, which is literally what happens when specific bacteria convert alcohol to acetic acid. Even then it is not toxic. So if you find a half-finished bottle from last week, trust your senses: if it smells and tastes fine, it is fine, and if it does not, pour it into a pan rather than down the sink.

How to make an open bottle last longer

A few easy habits can stretch any of the ranges above, and none of them require special gear.

Recork and refrigerate, always. Cold is your best free tool. Put reds in the fridge too, then pull the bottle out 20 to 30 minutes before serving so it warms back toward room temperature.
Pour into a smaller bottle. If half the bottle is gone, transferring the rest into a clean half-bottle leaves far less air in contact with the wine. This is the single most effective trick.
Use a vacuum stopper. The little pumps that suck air out of the bottle buy you an extra day or two for a few dollars.
Try inert gas. A spray of argon or nitrogen lays a protective blanket over the wine so oxygen cannot reach it, which works better than a vacuum for delicate bottles.

For an everyday bottle, recorking and refrigerating is genuinely enough. The fancier tools matter most when you want to open something special and drink it over a week, or when you are comparing how a wine changes night to night, the way you might when figuring out whether a bottle was good value.

What about a bottle you have not opened?

This is a different question with a happier answer. An unopened, well-stored bottle lasts far longer, because the cork keeps almost all the air out. But “lasts” is not the same as “improves.” The large majority of wine sold today is made to drink within a year or two of release and will not get better with age. A 15 dollar grocery-store red is at its best now, not in a decade.

Only a small share of wines, structured reds, high-acid whites, and sweet or fortified bottles, are built to age for years, and they ask for proper conditions: cool, dark, a steady temperature, and the bottle resting on its side so the cork stays moist. For everything else the practical rule is short. Buy it, keep it somewhere cool and dark, and drink it within a year or two. The romance of the dusty cellar applies to a small, deliberately chosen slice of the wine world, and almost never to what is on the supermarket shelf.

Let the wine tell you how long it has

The pattern underneath all of this is that a wine’s style is also its shelf life once opened. Crisp and high-acid, tannic and bold, sweet, or fortified: each of those tasting traits is a clue to how many days you really have. That is the kind of reasoning AboutWine is built to do for you. Point your phone at a label and it explains what the wine actually is, including the structure that tells you how long it will keep after you open it, in plain language rather than a number. It’s in early access now.

So the honest answer to how long wine lasts after opening is: longer than most people think for sturdy reds and sweet wines, shorter for delicate whites and sparkling, and always longer if you keep the air out and the bottle cold. When in doubt, give it a sniff. Wine is far more forgiving than the panic over a half-finished bottle suggests, and the few days you have are usually plenty. The only real mistake is the one nobody makes on purpose: leaving a good bottle open and warm on the counter, then wondering the next evening why it tastes like a different, sadder wine.

Frequently asked questions

Can you drink wine that has been open for a week?

Usually yes, if it was recorked and refrigerated, though it may taste flatter than it did on day one. Most light whites and rosés hold up close to a week, while delicate reds fade faster. A week-old open wine will not make you sick; the worst case is that it tastes dull or slightly sour, in which case it is better used for cooking.

Does wine go bad if you leave it out overnight?

Leaving a bottle out overnight on the counter is not dangerous, but it does speed up oxidation because the wine is warmer and exposed to air. A sturdy red will likely still taste fine the next day. The fix is simple. Recork it and put it in the fridge, even reds, then let a red warm back up before you pour it.

Is it safe to drink oxidized wine?

Yes. Oxidized wine has lost its fresh fruit and may smell nutty, flat, or vinegary, but it will not harm you. Wine is not like milk or meat that spoils into something unsafe. The only reason to pour it out is taste, and even then a mildly tired bottle is perfectly good for cooking or a marinade.
