Does Wine Go Bad or Expire? Everything You Should Know

Yes, wine can go bad, but an unopened bottle changes slowly and an opened one changes in days. Most bottles are made to be drunk within a couple of years, and heat is the fastest way to damage one. Below: how long each kind lasts, how to store it, and what spoiled wine looks and smells like.

Does wine go bad?

The short answer: Yes, but the figures are quality windows, not expiration dates. WSET says most wine is meant to be drunk within a couple of years after bottling. An opened bottle fades in days, and WSET gives up to five days for a re-closed red or white in the fridge. Heat, oxygen and a failed cork are the usual causes.

How Long Does Unopened Wine Last?

Start with the bottle in front of you. These are drinking-quality windows from educators, wine boards and producers, not expiration dates.

Most wines are meant to be drunk within a couple of years of bottling, and a well-stored bottle changes slowly. WSET’s wine myths article says most wines are meant to be drunk within a couple of years after bottling, and that only a small number of wines benefit from ageing. That is a drinking window, not an expiration date.

These are drinking-quality guides, not safety dates. We found no agency, such as FDA or TTB, that sets a shelf life for bottled wine.

Why Does Wine Go Bad?

Wine goes bad mainly through oxygen, heat and bacteria. WSET’s guide to common wine faults says oxidation happens when wine meets too much oxygen, which can come from a faulty closure or from an opened bottle left for a number of days. It says volatile acidity involves acetic acid and related compounds made by certain bacteria in the presence of oxygen.

The closure matters before you open the bottle, too. AWRI’s closure fact sheet says how much oxygen a closure lets through can change how long a wine lasts. It links very low rates to reductive attributes, and high rates to oxidised characters over a relatively short shelf life.

Heat speeds up the damage, and light adds to it. WSET says to keep wine away from bright light, whether sunlight or fluorescent and LED bulbs. AWRI cites lab tests in which white wines in clear glass developed an off flavor after about 3 hours of fluorescent light, against about 18 to 31 hours in green glass. We’d treat that as a reason to avoid bright light, not as a home timeline.

How Should You Store Unopened Wine?

Keep unopened wine cool, steady, dark and out of the kitchen. WSET’s page on wine service and storage temperatures says a storage area should sit below room temperature, at 10 to 15°C (50 to 59°F). It names the kitchen among the worst spots, because the room sees large temperature swings. The table shows what each source gives.

For bottles you plan to keep a while, lay natural corks on their sides. WSET says an upright bottle can risk a crumbling cork and extra air, while a bottle laid flat keeps the cork touching moisture. The guidance is aimed at wine kept for a long time, and we found no source on how long a bottle can stand upright before it matters. The Missouri Wine and Grape Board’s storage page says lying bottles down keeps the cork damp, which it links to avoiding premature aging. AWRI’s transport and storage page also recommends a cool, dry spot with the cork in contact with the wine.

Avoid swings, vibration and dry air. AWRI says daily temperature cycling should be avoided, and WSET says vibration can unsettle a wine’s flavors. The Paso Robles Wine Country Alliance’s storage guide puts cellar humidity at 60 to 80% and says drier air can dry out corks. AWRI adds that wines under natural closures can leak more in dry air, and that most storage facilities do not adjust humidity.

Short stays are lower risk than heat. We found no official figure for how long a bottle can sit at room temperature, and warmer storage ages wine faster, as the next section shows. We’d keep it away from the stove, the window and the car.

A refrigerator is fine for a short stay. The Missouri board’s earlier tips page says a fridge may be fine for a couple of months but can dry out corks. WSET warns that corks can lose their elasticity if wine stays in the fridge too long. Our guide on whether wine needs to be refrigerated covers it in detail.

What Does Heat Do to Wine?

Heat is the fastest way to damage wine. WSET says long spells in a hot place can strip a wine of fresh fruit and leave it dull and stale. It adds that heat can make the bottle expand and force the cork out, or weaken the seal and let air in.

The table shows where sources raise concerns. Purdue Extension’s wine storage sheet, written by an enology professor, says any temperature above 60°F accelerates maturation. AWRI’s technical note on heat and light says too-high storage temperatures shorten the shelf life of bottled wine markedly. Both are older and aimed partly at industry storage, so we’d read them as a guide to risk, not a countdown.

A parked car gets there fast. In a test by the National Weather Service, a parked van with the windows closed on a mostly sunny day started at 94°F outside. The interior passed 100°F about six minutes in, and reached 115°F within about half an hour. The NWS says a smaller vehicle would heat faster.

That is one van on one day, not a wine study. We’d read it as a reason not to leave bottles in a parked car in warm weather. AWRI says heat-exposed wine tends to lose fresh fruity character, and extreme exposure can show oxidised and cooked notes. It adds that thermal expansion can move the cork, which may change the look of the bottle without necessarily changing the wine.

How Can You Tell If Wine Has Gone Bad?

Check the look, the cork and the smell first. A brown tinge, a vinegar or nail polish smell, a damp cardboard smell and a cork pushed out of the neck are the usual signs. We don’t suggest tasting to test.

WSET’s faults guide describes the common problems and what causes them.

Can Bad Wine Make You Sick?

Most wine faults affect flavor and aroma rather than safety, based on what we found. WSET says a corked wine is unpleasant but not harmful to drink. Penn State Extension’s volatile acidity page and Oklahoma State Extension’s volatile acidity fact sheet both treat volatile acidity as a wine fault, with a vinegar or nail polish remover smell. Penn State notes federal limits of 0.14 g/100 mL for red wine and 0.12 for white, and neither page says anything about health.

Those are an education body and two university extension fault guides. We found no FDA, USDA or extension statement establishing that every spoiled bottle is safe, and none on mold in an opened bottle. If you see mold or unusual growth, or suspect contamination, we’d discard the bottle, and we don’t suggest tasting to check.

Does Wine Go Bad After Opening?

Yes, and much faster than an unopened bottle. WSET’s guide to keeping wine fresh says a red or white wine closed back up and kept in the fridge stays reasonably fresh for up to five days. Coravin’s opened wine guide gives red wine 3 to 5 days and white wine up to 3 days, and says light whites hold about 2.

Sparkling wine fades fastest, with most producer guidance at 1 to 3 days under a sparkling stopper. Fortified wine lasts longer, from days for a fino sherry to months for tawny port. Our guide on how long wine lasts after opening gives each type, plus whether stoppers and vacuum pumps work.

Do Sparkling, Fortified and Boxed Wines Go Bad?

Yes. Each kind has its own clock.

Sparkling wine loses its fizz first. Unopened windows range from the year after harvest for Prosecco to several years for Champagne. Opened bottles last 1 to 3 days with a stopper. See whether Champagne goes bad and whether Prosecco goes bad.

Fortified wine holds longer once opened but still fades. The Sherry regulatory council’s conservation guide says an unopened fino or manzanilla keeps up to a year and most other sherry up to three years. Lustau’s advice page gives the same closed windows. Opened, the council allows up to a week for fino and manzanilla and up to two months for other sherry, tightly corked in the fridge. Opened port runs from 2 to 3 days for vintage to 2 to 3 months for tawny, per Sandeman’s guide to drinking port. Vermouth is wine-based and has its own guide on whether vermouth goes bad.

Boxed wine lasts longer once opened because the bag collapses as you pour. UF/IFAS’s publication on wine packaging says newer bag-in-box designs have an oxygen barrier on the bag, spout and closure, and keep wine fresh for two to three weeks after opening. Black Box’s boxed wine storage page says an opened box stays fresh for up to six weeks. A 2012 UC Davis report found that at 68°F and 104°F bag-in-box wine aged significantly faster than bottled wine, and that all the wines aged best at 50°F. The sources differ, so we’d plan on the short end. Cooking wine is a different product, covered in whether cooking wine goes bad and whether cooking wine needs to be refrigerated.

Can You Freeze Wine?

Yes, with care, though we found no official guidance on freezing wine. Coravin’s page on freezing wine, a wine preservation maker, says most wines freeze around 15 to 20°F, and that the pressure can push out the cork or crack the bottle. It says a gentle thaw usually returns wine to a safe-to-drink state, though quality may suffer, especially for delicate styles. It also says thawed wine may still be fine for cooking, sangria or cocktails, and that sparkling wine can burst. Thawed wine may show tartrate crystals, which the Canadian Food Inspection Agency says pose no health risk.

We’d freeze leftover wine in ice cube trays or a container with room to expand, then use it in cooking. A wine-glazed ham or a red wine summer sangria is a good place for the extra.

How We Checked This
In October 2026 we read WSET’s guides on keeping wine fresh, common wine faults, wine temperatures and wine myths. We read Purdue Extension’s wine storage guidelines (marked 03/10), AWRI’s technical note on heat and light, its transport and storage page and its closure fact sheet. We read UF/IFAS’s 2024 publication on wine packaging and UC Davis’s 2012 report on bag-in-box storage. We read the National Weather Service’s parked vehicle test, the Missouri Wine and Grape Board’s two storage pages and the Paso Robles Wine Country Alliance’s storage guide. We read Penn State and Oklahoma State Extension’s volatile acidity pages. We read TTB’s sulfite labeling page and the Canadian Food Inspection Agency’s wine diamonds fact sheet. We read the Sherry regulatory council’s conservation guide, Lustau’s advice page, Sandeman’s port guide, Black Box’s boxed wine page and Coravin’s opened wine guide and freezing page. We found no FDA or USDA shelf-life guidance for wine and no university figure for an opened bottle. Where we found no source we say so, and our own suggestions say we’d or we suggest.
