Not that i want to make any, but how does the process of copper kettles and coil work?

thats just for distillation. the initial mixture of fermented fruits and water, containing up to 16% ethanol is evaporated in the kettle. For the system ethanol/water the ethanol concentration in the vapour is much higher than in the liquid (if you stay well below 97something % ethanol) because of relative volatility, chemical potential and such. that vapour is then condensated in the coil, resulting in a liquid with a higher ethanol concentration.
