Hands up: it’s rare that we wouldn’t finish a bottle of bubbles.

If, however, you do happen to have some Prosecco or Champagne (swit swoo) left at the end of an evening and you’d like to keep it fizzy until tomorrow, there’s an ingenious tip you should know about.

Before you go to bed, pop the handle of a metal spoon into the neck of the bottle.

Here’s the science bit: Once you pop the cork on a bottle of bubbles, the CO2 that keeps it fizzy begins to disappear. The thinking is that popping a metal spoon inside the bottle keeps the air colder, making it denser and preventing CO2 from escaping.

There are science folk who claim it’s an old wive’s tale but plenty of Prosecco drinkers disagree…

Little trick I learned living in Italy a million years ago….pop a teaspoon upside down into your bubbles and it keeps it fizzy for days. No idea why it works though pic.twitter.com/PVEQyjpV5Q

If you leave a bottle of Prosecco open overnight it will still be bubbly the next day, but employing this spoon trick definitely makes for more effervescent leftovers.
