BRL Hardy, the Australian wine giant is to use DNA from 100-year-old grapevines, in the latest effort to stamp out fraud in the wine industry. The move comes after growing concerns from the trade and wine-buying public after a series of high-profile fraud cases in the last 12 months. The Australian industry was most-famously rocked in 1998 when fake bottles of the country's leading premium wine Penfolds Grange were discovered.
