As the festive season approaches, many of you will be looking forward to popping open a bottle of champagne. But before you treat yourself to a bottle, do check out the December 2015 issue of Physics World magazine, in which fizzy-wine physicist Gérard Liger-Belair from the University of Reims Champagne-Ardenne reveals his top six champagne secrets.
In the article, Liger-Belair explains why a fog appears when you pop open a bottle, the angle at which you should pour the wine into a glass, and how many bubbles there are in a typical glass of fizz. He also wades into that age-old question among sparkling-wine aficionados: flute or coupe?
The new issue also contains a fabulous flow chart, in which you can find out what sort of scientist you are. Don’t miss either our look back at the International Year of Light, a fantastic selection of Christmas books and a feature all about how origami is moving from art to application.
If you’re a member of the Institute of Physics (IOP), you can get immediate access to this article in the award-winning digital edition of the magazine on your desktop via MyIOP.org or on any iOS or Android smartphone or tablet via the Physics World app, available from the App Store and Google Play. If you’re not yet in the IOP, you can join as an IOPiMember for just £15, €20 or $25 a year to get full digital access to Physics World. You can also read Liger-Belair’s article online here.
