Rare and old whisky can be a significant investment, except for when they are fraudulent. One report found that about one-third of rare whisky (and wine) may be fake, leading to $1.5 billion in losses in Europe alone. A handheld device is now able to detect fraudulent products rapidly. The analysis method involves electrodes that analyze characteristic groups of molecules that can be found in the real product. The device then checks the results against real whisky samples from a database.
