Once a bottle is open, oxygen starts to change it. Most wines are good for a day or two with the cork back in the fridge. The right preserver stretches that to a week, or with Coravin, lets you pour a glass without ever opening the bottle.

There are three approaches. A vacuum pump removes some air. Argon gas forms a protective layer over the wine. Coravin pours through a needle in the cork and replaces the wine with argon, so the bottle never really opens.

Best overall

Coravin Timeless Three Plus

Method
Needle through cork + argon
Keeps wine
Weeks to months
Best for
Collectors, expensive bottles

Coravin is what restaurants use to sell premium wine by the glass. A thin needle goes through the cork, argon pushes the wine out, and the cork reseals itself. You can have one glass of a special bottle tonight and another months later.

Watch outThe system and argon capsules are an ongoing cost. It works with natural cork, not screw caps, unless you buy the screw caps.

Best mid-range

Coravin Pivot Plus

Method
Special stopper + argon
Keeps wine
Up to about 4 weeks
Best for
Everyday bottles over several days

With the Pivot, you open the bottle normally, replace the cork with a Coravin stopper and pour through it. Argon protects what is left. It is a cheaper, simpler way into Coravin for wines you drink over a week or two.

Watch outIt does not keep wine for months like the Timeless.

Best budget

Vacu Vin Original Wine Saver

Method
Vacuum pump + stopper
Keeps wine
A few extra days
Best for
Finishing a bottle within a week

The Vacu Vin pump has been around for decades for a reason. Pump the air out, and the bottle keeps noticeably better for a few days. Buy extra stoppers if you often have more than one bottle open.

Watch outSome experts feel vacuum can reduce aroma on delicate wines. Best for short periods.

Best value argon

Private Preserve Wine Preservation Spray

Method
Inert gas spray
Keeps wine
Several days
Best for
Whites, rosé, any closure

A short spray of inert gas into the bottle before you put the cork back covers the wine and slows oxidation. It is cheap, works with any bottle and does not pull aroma like a vacuum can.

Watch outYou cannot see how well you covered the wine; follow the spray instructions.

Best for bubbles

Coravin Sparkling

Method
Pressurized stopper + CO2
Keeps wine
Up to about 2 weeks
Best for
Champagne, Cava, Prosecco

A regular stopper lets bubbles escape. Coravin Sparkling repressurizes the bottle, so a Champagne opened on Friday still has fizz the next weekend.

Watch outOnly for sparkling wine. Not for still wines.

A note from the floor

Whatever you use, put the bottle in the fridge, red included. Cold slows oxidation. Take a red out about 30 minutes before you pour so it comes back up to serving temperature.

How to choose

If you finish bottles in a few days, a vacuum pump or argon spray is enough. If you want a glass at a time over weeks, get a Coravin Pivot. If you collect fine wine, the Coravin Timeless pays for itself in bottles you do not waste.

Questions guests ask me

How long does an open bottle of wine last?

With the cork back in and in the fridge, most whites and rosés last 3 to 5 days and most reds 3 to 5 days. Light, delicate wines fade sooner; sweet and fortified wines last much longer.

Is Coravin worth it?

If you often want a single glass of a bottle that costs more than $40, yes. For everyday wine you finish quickly, a pump is enough.

Does a spoon in the bottle keep Champagne fizzy?

No. That is a myth. Use a proper sparkling stopper.
