How long does wine last once opened?
A practical guide to keeping leftover wine drinkable
Still red wine lasts 3–5 days after opening when re-corked and refrigerated. Still white and rosé last 2–4 days. Sparkling wine lasts 1–3 days with a sparkling wine stopper. Fortified wines (port, sherry) last 1–8 weeks depending on style.
Once you open a bottle of wine, oxygen begins to break down its aromas and flavours. At first (the first few hours), oxygen can actually improve a young, closed wine by softening tannins and opening up aromatics. But beyond that, extended oxidation progressively flattens the wine, turning it vinegary and then to acetic acid — essentially, wine vinegar.
The rate of oxidation depends on several factors: how much wine remains in the bottle (less wine = more oxygen = faster oxidation), the wine's structure (high-acid and high-tannin wines last longer), and storage temperature (cooler = slower oxidation).
Refrigeration is the single most effective measure. Putting an open bottle of red wine in the fridge, rather than leaving it on a warm kitchen counter, can double or triple its drinkable life. Remove the bottle 30 minutes before serving to let it come back to temperature.
- Red wine: 3–5 days refrigerated. White/rosé: 2–4 days. Sparkling: 1–3 days.
- Refrigeration is the most effective way to extend opened wine.
- The less wine left in the bottle, the faster it oxidises.
- Vacuum pumps and inert gas sprays further extend life.
- Fortified wines (sherry, port) last much longer than still table wine once opened.
The re-closure method matters. A wine vacuum pump removes oxygen from the bottle and can extend life by a day or two. Argon or nitrogen wine preservation sprays displace oxygen with an inert gas and are even more effective. A proper stopper (or even the original cork) is better than leaving the bottle open.
Half-empty bottles oxidise faster than near-full ones because the ratio of oxygen to wine is higher. If you have significantly less than half a bottle left, consider pouring it into a smaller vessel (a clean 375ml bottle, for example) to minimise headspace.
Special cases: fortified wines like tawny port, oloroso sherry, and Madeira are partially oxidised during production and remarkably robust once opened — sometimes lasting weeks. Vintage port and fine aged wines, by contrast, can decline within hours of opening. Sparkling wine loses its carbonation quickly; a sparkling wine stopper in the fridge preserves bubbles for 24–48 hours.

Can I cook with wine that has gone off?
Only if it has turned to vinegar and you want its acidity, not its flavour. Wine that has oxidised but not vinegared is fine for cooking — the heat drives off the delicate aromatics that have degraded anyway, leaving the structural flavour. But wine with obvious vinegar or musty notes will ruin a dish.
Does a wine stopper really work?
A basic rubber stopper is better than leaving the bottle open but does not significantly outperform re-inserting the original cork. Vacuum stoppers (which pump air out) add a day or two of life. Inert gas sprays (argon/nitrogen) are the most effective method for preserving opened wine.
How do I know if opened wine has gone off?
Oxidised wine smells flat, nutty, or vinegary. The fruit is muted and the finish is harsh or sour. The colour of red wine turns brick-orange at the rim when oxidised. If in doubt, taste a small sip — the difference from fresh wine will be obvious.
