Don’t pour away your flat prosecco, a simple kitchen item will instantly revive it – you probably already own it

IF YOU couldn’t quite get through a full bottle of prosecco or Champagne last night you could well have been left with some flat fizz this morning.

However, before you tip the pricey booze down the sink there is a simple method to instantly revive it, and experts agree that it works.

According to wine expert Jonny Inglis, founder of WineDrops.com, a simple raisin is the key to getting bubbles back in your bottle.

Explaining the science behind the hack, Jonny says: “The key lies in its surface area. 

“The raisin acts as a nucleation surface, which allows the remaining CO₂ in the champagne to collect and form bubbles. 

“Once the CO₂ reaches critical mass, it redistributes through the wine, creating that familiar fizz.”

However, Jonny is quick to point out that this hack isn’t a magic fix. While a raisin can briefly restore some effervescence, the effect is fleeting and comes at a cost. 

“Using this method actually speeds up the overall loss of carbonation,” he explains. 

“You’d better drink it quickly, as your champagne will go flatter even faster in the long run.”

So, while it’s fun to try this viral trend, Jonny cautions that it’s best reserved for emergencies, a last-ditch effort to salvage a special moment or save a glass of bubbles from going to waste.

Ever been told to pop a spoon into the neck of an open champagne bottle to keep it fizzy? Jonny isn’t buying it.

“There’s no scientific evidence to support this,” he says. “The idea is that the metal cools the air in the bottle’s neck, slowing gas expansion, but it doesn’t actually work.”

Instead, Jonny advises investing in a proper champagne stopper. 

“These stoppers create a hermetic seal, which is the only effective way to prevent CO₂ from escaping,” he explains. 

“For the serious fizz fanatic, vacuum pumps are another option, as they help slow down oxidation in the fridge.”

Does shelling out more money on a bottle guarantee longer-lasting fizz? According to Jonny, the answer lies in the science of bubbles.

“The size of the bubbles is the key factor,” explains Jonny. 

“The smaller the bubbles, the slower the release of CO₂, and the longer your champagne will stay fizzy.

“And here’s the kicker: smaller bubbles tend to come with a higher price tag. Premium champagnes and sparkling wines made using the Traditional Method, a labour-intensive production process naturally produce tiny bubbles. 

“In contrast, budget-friendly sparklers made with Tank Method or CO₂ Injection result in larger, quicker-dissipating bubbles.

But there’s more to it than just bubble size. Jonny says another hallmark of top-quality champagne is lees aging. 

“Lees aging, which is only used for the most expensive sparkling wines, allows the liquid to absorb more CO₂, helping it stay fizzier for longer,” he says. 

So, while a pricier bottle may dent your wallet, it will keep your glass sparkling well after it’s been opened.

That said, Jonny admits this might be overkill for most people. “Personally, I’ve rarely had a bottle of fizz hang around long enough for this to be an issue.”
