Keep Your Champagne Bubbly With A Spoon

If you can't finish a bottle of champagne after you've popped the cork, don't dump it down the drain. Here's a handy trick that might keep it fizzy and drinkable for at least another day.

Bon Appetit's Heather John says grab a metal spoon and drop the handle into the neck of the champagne bottle. (A fork should work just as well, but skip the knife because you don't want the utensil falling all the way into the bottle. )

John says that although the spoon-in-the-bottle trick has kept her champagne fresh for as long as 24 hours, it's often denounced as nothing more than an old wives' tale. The industrious folks over at Kumkani Wines decided to find out for themselves and ran a little experiment to find out whether this method really works. After what must have been an exhausting trial apparently involving a crate of champagne, a camera and several weekends of imbibing ("It was a struggle, but we'll do anything for science," notes one of the, uh, researchers), they drew some final conclusions.

It turns out that putting a metal spoon in the neck of a champagne bottle does preserve much of its effervescence. The team also came up with a potential theory for why it works:

What we think is happening is that the spoon is acting as a radiator and when it hangs in the bottle, the air inside the neck of the bottle cools faster than the air inside a bottle without the spoon. Because we had measured the temperature drop inside each bottle we could confirm this.

Now, colder air is denser than warmer air, so the bottle with the spoon gets a ‘cold plug‘ on top of the wine sooner than the bottle without the spoon. The weight of this colder denser air means that less gas can escape so the bubbles are preserved. In addition, cold bubbly keeps more of its carbon dioxide in solution than warm.

Have you ever tried this method with leftover champagne? Got any extra insight on why it might work? More to the point, who actually ever has leftover champagne? Isn't that like leaving one cookie in the bag? Enlighten us in the comments.

How To Keep Champagne Bubbly [Bon Appetit]


    The "research" was *not* done by kumkani wines - go read the article, or search for snippets of the text.

    uhh mythbusters did this.. and guess what?

    they BUSTED IT.

      Because YOU should believe EVERYTHING you see on TV.
      ESPECIALLY Mythbusters - because those guys are [s]scientists[/s] smart prop guys..

    Not bullshit until you have tried it. Works equally well with the metal thingy that keeps the cork on, squeezed together to fit down into the bottle neck. Very simple, very effective.

    Even if this does do something wouldn't sticking another cork or using cling wrap would make a better plug than the "cold plug"

    Or you could just spend 10 bucks and get a champagne stopper that will last for the rest of your life.

    YEs - it looks like Kumkani wines did not do the research - just an interesting artice on their blog site. Kumkani Infiniti sparkling is excellent however.

    Um, this has been done to death - Mythbusters, also New Scientist to pick the two most obvious ones I know about.

    Short version: Put the spoon in the neck of the bottle and it keeps its fizz overnight in the fridge. Then do the control experiment: Keep a bottle in the fridge with no cap but without the spoon. It will also keep its fizz.

    Basically the carbon dioxide sits in the bottle and leaches much more slowly from the drink than you'd expect. The spoon has nothing to do with it.
