What is the difference between fermentation with distillation and without distillation?

Dear student,
Fermentation is the process of converting sugar such as glucose and fructose into ethanol using microbes. The ethanol formed is not pure, so without distillations impure ethanol is formed with little ethanol content but with distillation ethanol is collected from the impure ethanol by distillation into another flask whose ethanol content is high.
