Keeping wine
How to keep an opened bottle of wine fresh
Reseal the bottle after pouring and put the remainder in the fridge, including red wine. Use a pressure-rated sparkling stopper for fizz. How long it tastes good depends on the wine, the air left in the bottle and how it is stored.

What to do with the bottle you have
Still white or rosé
- First step
- Reseal and refrigerate promptly.
- What to watch
- Color alone does not predict how long it will retain its character.
Sparkling
- First step
- Use a sparkling-wine stopper and refrigerate.
- What to watch
- Loss of fizz can happen before you notice a large change in aroma.
Wine opened with a preservation system
- First step
- Follow the instructions for that exact system and closure.
- What to watch
- Bottle compatibility, setup and consumables affect performance.
Start with the closure and the fridge
Replace the screwcap or use a clean stopper that fits the bottle. Keep opened wine upright in the fridge. If the cork is damaged, use a suitable replacement rather than leaving the bottle open. For sparkling wine, choose a closure designed to hold pressure.
A half-full bottle contains more air than a nearly full one. Opening it repeatedly brings in more air. If you often save only a small amount, a clean, smaller bottle with a tight closure can reduce the headspace for still wine. Use equipment intended for food and drink.
How many days will it last?
Think in terms of changing quality, rather than an exact expiry date. Ordinary opened table wines often remain enjoyable for a few days when resealed and refrigerated, but some fade sooner. Sparkling wine also loses its bubbles. Fortified wines vary widely and need style-specific advice.
Write the opening date on the bottle. Compare the fruit aromas, freshness and overall taste when you return to it. A flatter, bruised-fruit or vinegary character can signal a change from what you enjoyed when first opened. This guide describes quality, not a food-safety guarantee.
Choose preservation around the way you drink
A stopper and your existing fridge are a reasonable first step. A vacuum system removes some air from suitable still-wine bottles. Gas-based systems use another approach to limit oxygen exposure. Follow the manufacturer's instructions for closures, wine types, bottles and consumables.
A costly device is only useful if it solves a real problem for you. Compare the wine you regularly discard with the device price and ongoing supplies. Our calculator lets you explore that tradeoff without assuming that every saved glass pays for an expensive system.
Bring a red back toward serving temperature
Pour a small amount and give it time to warm if it feels too cold. Keep the rest refrigerated while you decide whether you want another pour. You can compare your first and later impressions in a note.
For a tasting at home, plan how you will store the leftovers before opening several bottles. Half bottles or a shared tasting can sometimes fit the occasion better than a larger purchase.
