An opened bottle of wine generally keeps for 3 to 5 days for a red, 2 to 4 days for a white or rosé, and 1 to 3 days for a sparkling wine, provided you reseal it and keep it cool. After that, the wine does not become dangerous, but it loses its aromas.

Why does wine spoil once it’s opened?

On contact with air, wine oxidises. The fresh fruit and flower aromas fade, then notes of overripe apple, walnut, varnish and eventually vinegar appear. The larger the surface of wine in contact with air, the faster this happens. Cold slows it down.

How long does each type of wine keep?

• Red: 3 to 5 days. Structured reds, rich in tannins, keep better than light reds.
• Dry white and rosé: 2 to 4 days, in the refrigerator.
• Sparkling: 1 to 3 days with a special stopper, as the bubbles fade quickly.
• Sweet and liquoreux wines: one to several weeks, thanks to the sugar that protects the wine.

What can you do to keep an opened bottle in better condition?

• Re-cork right away, with the original cork or a well-fitting replacement stopper.
• Putting it in the fridge, even a red: cold slows down oxidation. Take it out 20 to 30 minutes before serving.
• Keep it upright: the surface of wine exposed to air is smaller than when the bottle is lying down.
• Transfer it to a smaller bottle when little wine is left: less air, less oxidation.
• Use an inert gas system if you open bottles often: it is more effective than a simple vacuum pump.

How do you reseal a bottle properly?

The original cork swells back up after a few minutes and sometimes will no longer fit. Do not force it: cut a thin slice off the cork with a knife, or use a silicone or rubber replacement stopper, available for a few euros. Push it in firmly, the aim is to stop air from circulating. There is no point turning the original cork round to its clean side: a new stopper is better than a forced cork.

Common misconceptions about storing opened wine

A spoon slipped into the neck of a champagne bottle has no proven effect. A vacuum pump does remove a little air, but it can also take some of the aromas with it, so its effect remains limited. The most effective method is also the simplest: a good stopper and the refrigerator.

How can you tell if an opened wine is still good?

Trust your nose first. If the wine smells of vinegar, nail polish or very ripe apple, or if it seems flat and lacking in definition on the palate, it has lost its qualities. A wine that is simply tired poses no health risk in the vast majority of cases, but its taste is no longer worth having at the table.

Which wines hold up best once opened?

Those with structure: tannins, acidity, a sustained alcohol level. A powerful red like the Lux Rouge (Grenache and Syrah, AOP Ventoux) will hold up better to two or three days open than a light, fruity red, which loses its charm more quickly.

What should you do with a wine that is no longer drinkable?

Use it in the kitchen. A tired red makes a very good base for a sauce, a beef bourguignon or pears in wine. A tired white adds flavour to a risotto, a fish dish or mussels. No need to throw it away.

Do low-sulphite wines keep less well once opened?

Often, yes. Sulphur protects wine from oxidation: a wine made with very little sulphur generally fades faster once the bottle is open. If you know you won’t finish the bottle, drink it within two days.

Can you freeze wine for cooking?

Yes. Pour the rest into an ice cube tray: once frozen, the cubes can go straight into a sauce, a gravy or a slow-cooked dish. Frozen wine is no longer for drinking, but it keeps enough flavour for cooking.

FAQ: open wine

Can you drink a wine that has been open for a week?

In most cases there is no health risk, but the wine has lost most of its aromas and may smell of vinegar. It is best used for cooking.

Should you put a red wine in the refrigerator after opening?

Yes, it is the best way to slow down its evolution. Take it out about 30 minutes before serving so it returns to its serving temperature.

Does a screw cap preserve wine better?

A screw cap reseals perfectly and protects an opened bottle well. It is a practical advantage, even though the wine keeps oxidising through contact with the air already in the bottle.
