Decanter magazine asked a question that we all too lazy to do: “is placed into the bottle and spoon to keep the bubbles in the champagne?”
In short, no. Said the editorial Board.
Despite the fact that this is a very popular “lifehack”, Professor of the University of Rheims (champagne-Ardenne) Gerard Liger-Belair (don’t know how it will be in Russian), says he has no idea where this idea with a spoon. “We did some experiments on this subject. No impact on saving CO2 in sparkling wine with a spoon does not provide,” he says.
Another expert on champagne makes the assumption that the fact that the bottle put in the fridge, which in itself helps slow the loss of CO2, and the effect is attributed to the spoon.
However, in the comments to the article were people who swears that a spoon works, – they say he checked, though not realized at the expense of what.
