A half-finished bottle in the fridge is one of the most common wine dilemmas — is it still good, or has it turned? How long wine lasts after opening depends heavily on style, and knowing the real numbers can save you from pouring out a perfectly good bottle, or drinking one that has already gone flat. This guide covers exactly how long every major wine style lasts once opened, and how to make it last longer.
Why Wine Doesn’t Last Forever Once Opened
The moment a bottle is opened, wine is exposed to oxygen, and oxidation begins immediately. In small doses, oxygen exposure can improve wine by softening tannin and releasing aroma — this is the entire principle behind decanting. But over hours and days, the same process strips away fruit character, dulls colour, and eventually turns wine flat, vinegary, or sherry-like. How long wine lasts after opening comes down to a race between beneficial aeration early on and destructive oxidation later.
How Long Wine Lasts After Opening, by Style
Light, Crisp Whites (Sauvignon Blanc, Pinot Grigio)
5 to 7 days, refrigerated with the cork or a stopper back in. High acidity acts as a natural preservative, giving these wines unusually good staying power. See our Sauvignon Blanc guide.
Full-Bodied, Oaked Whites (Chardonnay)
3 to 5 days, refrigerated. Lower acidity than crisp whites means oxidation shows up a little sooner. See our Chardonnay guide.
Rosé
3 to 5 days, refrigerated, similar to whites of comparable acidity.
Light to Medium Reds (Pinot Noir, Chianti)
3 to 5 days, stored with the cork back in at cool room temperature, or refrigerated to extend it slightly further. See our Pinot Noir guide.
Full-Bodied, Tannic Reds (Cabernet Sauvignon, Syrah, Bordeaux)
5 to 7 days. Higher tannin acts as a preservative in the same way acidity does in whites, giving these wines the longest lifespan of any still wine. See our Cabernet Sauvignon guide.
Champagne and Sparkling Wine
1 to 3 days at most, and only with a proper sparkling wine stopper — once the bubbles go flat, they do not come back. See our Champagne guide.
Fortified Wine (Port, Sherry)
Tawny Port and Sherry can last 2 to 4 weeks refrigerated thanks to their high alcohol content and, in Sherry’s case, already-oxidative style. Vintage Port is more fragile and is best finished within a few days. See our Port wine guide.
How to Make Opened Wine Last Longer
- Put the cork back in and refrigerate — even red wine benefits from refrigeration once opened; just let it warm up before your next glass. See our wine serving temperature guide.
- Use a vacuum pump — removing air from the bottle slows oxidation meaningfully, though it won’t preserve sparkling wine’s bubbles.
- Transfer to a smaller bottle — less air in contact with the wine means slower oxidation; a half-full bottle poured into a clean half-bottle can noticeably extend freshness.
- Use inert gas spray — wine preservation sprays blanket the wine with an inert gas layer that keeps oxygen away from the surface, popular with wine professionals for expensive bottles.
Signs Your Opened Wine Has Gone Bad
A wine past its window will smell flat or like bruised apple and sherry, taste dull with no fresh fruit, and may show a brownish tinge. These are the classic signs of oxidation — see our wine faults guide for how oxidation compares to other issues like cork taint. Oxidised wine is not dangerous to drink, simply unpleasant; if in doubt, taste a small amount before pouring a full glass.

Final Thoughts
How long wine lasts after opening varies from one day for Champagne to several weeks for fortified wine, but the fix is almost always the same: recork it and refrigerate it. Keep a vacuum pump on hand for everyday bottles, and you will waste far less good wine.
