Australia’s wine industry is investigating the possibility of converting its massive wine oversupply into biofuel ethanol. Industry leaders say the country’s 263-million-litre surplus — mostly red wine — could produce around 30 million litres of ethanol through distillation. Experts from the University of Adelaide say the concept is scientifically viable, as wine ethanol is similar to that used in E10 fuel after purification. The proposal comes as global wine consumption falls to levels not seen since 1961, creating financial pressure on grape growers and wineries across Australia.
