Prices are prohibitive and rise inexorably on the gray market of champagne speculation.
Bottles sold for 300 euros in 2008 can for example be offered for several thousand euros on auction sites, notes France Bleu Champagne-Ardenne.
Marne winegrowers decided last April to use electronic tracking to combat the phenomenon.
Guillaume and Anselme Selosse, two operators from Avize (Marne), had the idea of inserting an NFT contactless chip on each tag.
If the bottle is scanned and entered into the system by its buyer, it is possible to know whether the vintage has been resold after its first purchase, but also whether it has been kept at an adequate temperature.
Quality also monitored
Thus, in addition to the different owners of the bottle thus monitored, the quality of the champagne it contains can also be monitored.
All very quickly with a simple smartphone.
The cost of each chip is 50 cents.
The device and app were developed by WID Group, a French company from Côte-d'Or.
