“Making sure a glass of wine is everything it promises on the label was once a relatively simple process: hold against the light, tilt and observe the shade, swirl a little and give it a good sniff. But with the ever-increasing global consumption of wine now attracting the attention of fraudsters, wine drinkers are soon just as likely to be advised to whip out their smartphones. A quick scan can give the consumer a direct link to the supplier’s website to verify the label, trace the wine’s journey from vineyard to glass and provide information about the winery. New technology and international cooperation are now enabling producers to outsmart the fraudsters.”
