Abstract
A method of producing a potable spirit comprises removing water from a fermented wash containing ethanol, water and congeners to produce a substantially water-free mixture of ethanol and congeners, and then fractionally distilling this water-free mixture of ethanol and congeners in the absence of water to produce a fraction containing substantially pure water-free potable ethanol. Preferably the fractional distillation is carried out in separate topping and tailing columns. This method provides an energy efficient separation of the ethanol and congeners.
