The Spoon Myth
Does a Spoon in the Bottle Keep Sparkling Wine Fizzy?
No, a spoon in the bottle neck does not keep the carbonation in sparkling wine. Blind tastings and comparison trials found no difference between bottles with and without a spoon. What actually keeps opened sparkling wine fresher longer is cold temperature and a tight seal.
Where Does the Silver Spoon Trick Come From?
Few household tips persist as stubbornly as this one. After the party, half a bottle is left over, someone sticks a teaspoon handle-down into the neck, and the next day the rest supposedly fizzes like it was just opened. A silver spoon is said to work best. Several versions of the explanation circulate. Sometimes it's claimed the cold metal forms a plug of cold air over the wine, other times that silver chemically binds the carbonation—meaning the carbon dioxide dissolved in the wine.
Neither explanation holds up to physics. A spoon doesn't seal the bottle; gas flows freely past the handle and out. Silver also doesn't form any bond with carbon dioxide that would trap the gas in the wine. The myth likely survives because it's so easy to try and almost always seems to work. A look at the experiments that have actually been done explains why.
What Have Experiments with the Spoon in Sparkling Wine Shown?
In 1994, Richard Zare, a chemistry professor at Stanford University, put it to the test with a small blind trial. Together with food writer Harold McGee and some acquaintances, he opened several bottles of sparkling wine and put them in the fridge for 26 hours: some with nothing, others with a spoon of silver or stainless steel in the neck. A panel of eight laypeople then rated how fizzy the wines still were, without knowing which bottle was which. No advantage showed up for the spoon bottles. Zare afterward simply called the trick a myth.
That same year, the French science magazine 'Pour la Science' reported on experiments from Champagne that reached the same conclusion. The German knowledge platform Planet Wissen also sums it up: opened bottles with and without a spoon lose the same amount of carbonation. For context, these are small trials, not large-scale studies. But for an effect that physics says shouldn't exist at all, this is plenty of evidence.
Why Does the Sparkling Wine Still Fizz in the Fridge Anyway?
Anyone who tries the spoon trick usually experiences a small success. The wine left in the glass still fizzes the next day, just weaker than the evening before. That's down to the cold, not the cutlery. Carbon dioxide dissolves much better in cold liquid than in warm, so at fridge temperature more gas stays in the wine and escapes more slowly. The bottle with the spoon is, as a rule, sitting in the fridge. The fridge does the work, the spoon gets the credit.
On top of that comes the high pressure sparkling wine starts with. Quality sparkling wine, called Sekt in German-speaking countries, must have at least 3.5 bar of pressure at 20°C, while Champagne typically runs around 6 bar. After opening, a lot of gas stays dissolved in the wine at first and only rises gradually. Some of it is still there the next day, spoon or no spoon. Anyone who doesn't run a comparison without the spoon easily mistakes this residual fizz as proof the trick works.
What Really Keeps Opened Sparkling Wine Fresh?
A tight seal is what matters most. A commercial sparkling wine stopper, which clips under the lip at the bottle neck with a clasp, keeps the rising gas inside the bottle. Some pressure builds back up there, and that pressure keeps more carbonation in the wine. An ordinary wine cork or plastic wrap, by contrast, barely seal at all. A cork can even get pushed out as pressure rises.
Cold remains the second lever. The resealed bottle should go straight back into the fridge, standing upright, so the wine has as little surface area exposed to air as possible in the narrow neck. The less wine left in the bottle, the larger the air space above it, and the more gas migrates there. A nearly empty bottle therefore goes flat faster than a half-full one. In the long run, though, even the best measures only help so much, since every opening costs pressure and freshness. Tips on temperature and pouring are gathered in the chapter on serving.
