First Ever Test Drive on Whisky Biofuel

Celtic Renewables Ltd set the wheels in motion of the first car to be fueled by a whisky residue biofuel. The fuel - biobutanol - is a new advanced and sustainable biofuel, which is a direct replacement for petrol and diesel. It is produced from draff - the sugar-rich kernels of barley which are soaked in water to facilitate the fermentation process necessary for whisky production - and pot ale, the copper-containing yeasty liquid that is left over following distillation.
