That, at least, says popular wisdom. However, although it partly closes the neck of the bottle, it does not do so to the extent of preventing gas leakage . In 1995, a team of physicists and chemists from the Interprofessional Center for Champagne Wines, in France, carried out a rigorous study of this phenomenon. He partially emptied many bottles of the same uncorked vintage in unison and determined the gas pressure variations during the experiment. Some open bottles lacked a spoon, others had a silver or a different metal. Other bottles were closed by an airtight stopper and a last batch was closed by a capsule. The conclusions of this study were that only the airtight cap retains pressure.
