You open a bottle, pour a glass, and something seems off. It happens to most wine drinkers at some point, and the first thought is usually the same: has my wine gone bad, or does it just need a few minutes to breathe?
Wine can change over time, and knowing what to look for can help you understand whether a bottle is at its best. Storage conditions, exposure to oxygen and the style of wine all influence how long it will retain its freshness and character. Here's how to recognise the different signs and get the most from every bottle.
How to Tell If Your Wine Is Still Fresh
To know whether your wine is still fresh and ready to enjoy, your senses are the best tool you have. Work through smell, appearance and taste in that order, and you'll usually have an answer pretty quickly. Here's what to look for:
Smell
- Vinegar or sharp acidity: The wine has oxidised beyond the point of drinking.
- Musty cardboard: This is the smell of a corked bottle, caused by a compound called TCA. Once a wine is corked, this cannot be reversed.
- Struck match or sulphur: This can sometimes blow off with air. Try giving the wine some time to breathe or decanting it before deciding whether it needs further attention.
Appearance
- A young red turning brown: Some browning at the edges is normal in older reds, but a noticeably brown or dull colour in a young red can be a sign of oxidation.
- A white going noticeably darker: Combined with a flat or vinegary smell, this usually means the wine has oxidised.
- Bubbles in a still wine: Worth a sniff and a taste before deciding what to do with it.
- Cloudiness: Not always a problem. Unfiltered wines are naturally hazy, and tartrate crystals are harmless. It's cloudiness alongside an off smell that's worth paying attention to.
Taste
- Flat and lifeless, or sharp and sour: The wine may have passed its best and lost some of its freshness and character.
- Muted with little fruit: Usually a sign of a corked bottle.
- Lacking freshness but not unpleasant: The wine is probably just past its best rather than actually bad, still fine for cooking.
Can Unopened Wine Go Bad?
An unopened bottle can still deteriorate, particularly if it's been stored in poor conditions. Heat, direct light and significant temperature swings all affect wine through a sealed cork, so a bottle left somewhere warm or exposed to sunlight over a long period is unlikely to be at its best when you come to open it. To learn more about what actually makes a difference, see our detailed guide on how to store wine at home.
Most wines are also made to be drunk within a few years of release. Do wines expire in the traditional sense? Not exactly, but holding on to an everyday red or white for a decade won't improve it. For more on that, read our guide on how long wine actually lasts unopened.
How Long Does Wine Last Once Opened?
How long your wine stays fresh depends entirely on the style of wine in the bottle. Delicate whites and sparkling wines lose their character quickly, while robust reds can handle oxygen exposure for a bit longer.
Does Red Wine Go Bad?
If you’re wondering how long red wine lasts after opening, the peak window is short. Once opened, most red wines are best within two to three days. Fuller-bodied styles like Shiraz or Cabernet Sauvignon hold up a little longer than lighter reds like Pinot Noir. Reseal and keep somewhere cool rather than leaving it on the bench. After three to five days, many reds will begin to lose some of their freshness and fruit character, regardless of how well they've been sealed. For more on how structure and tannin affect a red wine's lifespan, see our guide to why red wine gets better with age.
Does White Wine Go Bad?
White wine is generally more delicate than red and turns faster once a bottle has been opened. Most whites are best within one to two days, kept sealed and refrigerated. Fuller styles like oaked Chardonnay hold up slightly better than lighter, more aromatic whites like Sauvignon Blanc or Pinot Grigio, which can start to lose their freshness within a day of opening.
How Long Does Champagne Keep Once Opened?
Once opened, Champagne is best enjoyed soon after serving to preserve its bubbles and freshness. A sparkling wine stopper and refrigeration can help maintain its character for a day or two. Unopened, store it on its side somewhere cool and dark. Non-vintage styles are generally best within three to five years of purchase.
Is It Safe to Drink Wine That Has Gone Off?
In most cases, yes. A corked or oxidised wine is generally safe to drink, although the wine's aroma and flavour may be affected. The faults are chemical rather than bacterial. Wine that just tastes dull and past its best can still be used for cooking. That said, if you notice visible mould or other unusual signs of spoilage, it's best to avoid drinking the wine.
How to Keep Wine Fresh for Longer
A few simple habits make a real difference to how long wine lasts once opened:
- Reseal the bottle tightly after every pour.
- Refrigerate both red and white wine after opening. Take red out 20 to 30 minutes before serving.
- Keep opened white and sparkling wines refrigerated.
- Use a vacuum wine stopper to remove air from the bottle before sealing.
- Keep bottles away from heat and direct sunlight.
- Decant leftover wine into a smaller bottle to reduce the air in contact with it.
