Your luxury wine may be fake Some hope to find a solution

“One of the top Burgundy producers was asking us if they could use our labels on all their bottles. Then we could create an extra step so that when you buy a bottle from, say, a distributor in the UK or the US, you can add to your wallet,” he says. bottle from a perfect chain of origin.”

Gaetano admits that, strictly speaking, Cruated’s system doesn’t prevent fraudsters from siphoning off the bottle’s contents (if they can bypass the NFC tag in the neck), but says that reliable authentication comes from never leaving the wine’s location .

If you find yourself needing to find out if a wine is the real deal, you need a completely different technological solution. the prize is the process of identifying what’s inside the bottle.

The number of different parameters tested – the age of the wine, the place of origin, the chemical composition – meant that the problem was attacked in different ways.The University of Adelaide team was can show that absorption-transmission-excitation-emission spectroscopy (A-TEEM), essentially a very sophisticated scan of a sample, can reliably identify the vintage of a selection of Shiraz wines, as well as accurately associate each with a specific subregion of the Barossa Valley.

Similarly, different studies have shown nuclear magnetic resonance (NMR) spectroscopy, which works along similar lines to an MRI scanner, can detect different levels of deuterium, hydrogen isotopes and different amino acids in wine, enabling scientists to identify different grape varieties and varieties.

Vineyard terroir can be “fingerprinted” by the amount of rain experienced in different areas known for chemically different rainwater; 2007 paper showed that analysis of “stable isotopes” in water used to make wine can accurately distinguish between regions in California and Oregon.

Perhaps surprisingly, even the most famous experts admit that it is impossible to detect a fake, no matter how nuanced the palette. But where the human nose is defeated, a team of academics from many institutions has published a paper 2023 which showed that by using a method called gas chromatography to analyze the aromas of 80 Bordeaux wines, they were able to differentiate between the harvests of seven distinct areas on the left and right banks of the river.
