With rising number of fraudsters copying their products, wine producers are now making use of technology with wine drinkers able to verify the label of their drink directly from the supplier's website with a simple scan through their smartphones that will also provide information about the wine's journey from the vineyard to the glass and about winery in general.
Fake wine and spirits can sour the drinks market, but new technology and international cooperation are now enabling producers to outsmart the fraudsters.
Castel, the largest producer of French wine, uses the technology on 13 million bottles for the Chinese market as well on exports to other emerging markets such as Vietnam where counterfeiting is most prevalent.
"The Chinese are asking for a lot of information and for reassurance regarding the origin of the product," said Franck Crouzet, spokesperson for Castel.
But Chinese crooks are by no means the only perpetrators of wine scams.
"China is the most notorious but the problem is worldwide," said Christophe Chateau, spokesperson for the Bordeaux Wine Council.
While many bottles are ugly reproductions easily spotted by a practised eye, others are quite clever.
And although little harm befalls a consumer uncorking bulk Chilean red instead of estate-bottled Bordeaux, the consequences can be lethal when criminals sell tainted drinks.
"Last year we had a case in the Czech Republic, at least 20 people died from drinking a counterfeit local spirit," said Pierre Georget, CEO of GS1 France, part of a Brussels-based non-governmental organisation which uses unique bar codes to thwart the conmen.
GS1 guarantees that bar code numbers are never repeated worldwide, assuring traceability and authentication for everything from spare car parts and prams to Chianti.
"Chianti had some problems in the past in Russia. Our consortium spends 100,000 euros ($132,000) each year on registering and protecting our wines," said Silvia Fiorentini, spokesperson for the Chianti Classico Consortium, which produces 35 million bottles annually, 80 percent of which is exported.
In order for wine lovers around the globe to feel confident they are drinking a bottle of wine originating in the hills of Tuscany, Fiorentini says Chianti Classico now carries a distinctive seal over the cap and neck of the bottle, marked with a unique number and code, as well as the appellation's trademark black rooster.
Many wine regions are doing the same, and producers eager to learn more about fighting counterfeiters attended GS1's presentation at Vinexpo, a major wine and spirits trade show held this past week in Bordeaux.
"In wine there is an enormous problem with counterfeiting," said Georget. "The idea is to use unique identification - a bar code or data matrix bar code - to identify each bottle of wine. This is the same technology we already use for the FDA for drugs in America."
But many say a bar code doesn't go far enough and that the seal must contain an inviolable hologram.
"GS1 is a good start but it needs to be combined with a physical security feature," said Damien Guille, sales manager for Tesa Scribos, a German company that produces so-called tesa VeoMark labels, used for brand protection in a wide variety of sectors, including luxury goods, car parts and wine.
The labels are scanned with a smartphone and Tesa Scribos counts among its customers the Bordeaux largest appellation, Bordeaux and Bordeaux Superieur producers, as well as merchants Barton & Guestier and Castel.
The Bordeaux Wine Council's Chateau said that Bordeaux as a whole had chosen to work with firms ATT, Prooftag and Tesa Scribos, but that some 15 similar technologies also existed.
"Two years ago at Vinexpo, we had zero clients. Now we have a long list," said Guille of Tesa Scribos.
