Laser detects fraud in old wine bottles

As expensive wines get dearer the problem with wine fraud increases. A team of researchers at the Centre d’études nucléaires de Bordeaux Draguignan (CENBG) has developed a method that will make life more difficult for fraudsters: Using a laser and studying how the light is reflected from the bottle they can identify when the bottle was made. The dating of the glass bottle has a precision of one or two years. So if you are going to fake a wine in the future you had better find a bottle that is as old as it claims on the label.
