Artificial Intelligence may be the answer to wine fraud. Scientists have in fact developed an AI tool that allows chemical compounds in wine to be traced back to specific châteaus.

To do so, they used gas chromatography, an existing analytical technique to separate and detect the components of a blend. They grabbed 80 wines harvested over 12 years from seven different vineyards in Bordeaux, clustered the results and voilà: each château wine was found to have its own chemical signature! 'Each château is a symphony: it is not a single note that distinguishes it, it is the whole melody,' Professor Alexandre Pouget of the University of Geneva managed to put it in a beautifully poetic way. With distinguishing the vintages, the programme still had some difficulty, but through routine it can continue to learn. Fraudsters may be careful: if the compounds in their liquid do not match the origin on the label, they fall through!
