How Long Does Open Wine Actually Last?

As conventional wine-service guidance rather than a measured finding: sparkling wine holds one to three days, light whites and rosé hold three to five days, full-bodied whites and most reds hold three to five days, and fortified wines like Port or Sherry can hold for weeks to months. The wine doesn't spoil the way food does; it oxidizes gradually, so these are ranges for when it starts noticeably losing character, not hard expiration points.
Why Does Sparkling Wine Lose Its Quality Fastest?
Sparkling wine's appeal is tied directly to its bubbles and bright, fresh acidity, both of which fade quickly once the bottle is open and the seal is broken. A specialized sparkling stopper that maintains some pressure extends this modestly, but even with one, sparkling wine is the shortest-lived category on this list.
Does Re-Corking Actually Help?
Yes, with limits. Simply pushing the cork back in slows oxidation meaningfully compared to leaving a bottle open to the air, since it reduces the surface area exposed and limits airflow. It doesn't stop oxidation entirely, and it does nothing for the wine's remaining freshness once several days have passed, but it's an easy improvement over an unstoppered bottle sitting out.
Is a Coravin Worth the Money?
For a specific reader profile, yes: someone who regularly wants a single glass from a bottle they're not ready to finish, particularly a more valuable or age-worthy bottle they want to taste over multiple sessions without committing to opening it fully. Coravin-style systems work by inserting a thin needle through the cork and using argon gas to displace the wine poured out, in theory letting you access a bottle repeatedly without ever removing the cork or exposing the remaining wine to oxygen.
There is a tradeoff, though. A Coravin works best with a natural cork that can reseal around the needle. It doesn't work the same way once a cork has been fully removed and re-inserted, and the specific cost of the device and refill canisters varies by model and isn't something to quote without checking current pricing directly from the manufacturer. If you mostly finish a bottle within a day or two of opening it anyway, a preservation system solves a problem you don't really have.
Does the Type of Closure Matter for How Long Wine Lasts Once Open?
Screw caps reseal cleanly and predictably, which makes them at least as effective as a re-inserted natural cork for slowing post-opening oxidation, sometimes more so, since a screw cap forms a tighter seal than a cork that's already been pulled once. If you're choosing between two otherwise similar bottles and know you likely won't finish one in a single sitting, this is a minor but real point in favor of the screw-capped option.
Does Putting Red Wine in the Fridge Help?
Yes, and this is worth doing more than most people realize. Cooler temperatures slow the chemical reactions behind oxidation, which extends how long an open bottle of red stays reasonably fresh, the same principle that makes refrigeration useful for white wine. The tradeoff is serving temperature: a red pulled straight from the fridge will taste too cold, so give it 20 to 30 minutes at room temperature before pouring rather than serving it straight out. For more on getting serving temperature right generally, see our wine serving temperature guide.
How Can You Tell if an Open Bottle Has Gone Off?
Check three things: does it smell notably flat or dull compared to when you first opened it, has the color shifted toward brown at the edges more than its age alone would explain, and does it taste thin or lifeless in the middle rather than simply less vibrant. Any one of these on its own might just mean the wine has faded a bit; several together mean it's genuinely past the point of being enjoyable. This is a different question from whether a wine was faulty to begin with; see our guide to wine faults if what you're noticing sounds more like a defect than ordinary post-opening fading.
What to Do With the Rest of the Bottle
If you know you won't finish a bottle the same night, decide in advance whether it's a candidate for the fridge, a re-cork, or a preservation system, rather than defaulting to leaving it on the counter. For a bottle you decanted earlier in the evening, note that decanting and post-opening storage are separate questions entirely; see our full decanting guide for the serving side of that decision.
Logging what actually happened to a bottle, how many days it held up, whether a preservation method made a real difference, builds a personal reference that's more useful than any general guideline, since it reflects your own storage conditions and your own palate.

An open bottle isn't on a countdown to ruin. It's on a gradual slide, and knowing roughly where it sits on that slide is what actually helps you decide whether to finish it tonight or save it for tomorrow.

FAQ
Does wine go bad after opening the way milk does?
No. Wine oxidizes gradually rather than spoiling the way perishable food does. It loses freshness and character over days, but drinking wine past its best post-opening window isn't a food-safety concern the way spoiled dairy would be.
How long does open white wine last in the fridge specifically?
Generally three to five days for most full-bodied whites, as conventional guidance rather than a fixed rule, with lighter, more delicate whites and sparkling wine on the shorter end of that range.
What's the best way to save half a bottle of wine without buying special equipment?
Re-cork it and refrigerate it, even if it's a red wine you'll serve slightly warmer later. This costs nothing and meaningfully slows oxidation compared to leaving a bottle open at room temperature.
Is it worth buying a vacuum pump stopper?
It offers a modest improvement over a simple re-cork for some drinkers, though the actual effectiveness is debated, since a vacuum pump removes air from the bottle's neck but doesn't fully replicate an inert-gas environment. A basic re-cork and refrigeration covers most of the practical benefit for typical home use.
