### Instruction: How is a distiller used?
### Response: A distiller is used in the production of alcohol or hard liquor.  It works by using heat to cause evaporation and condensation with a source substance.  If you take water for example, distilling happens when you heat the water and then it evaporates into steam and then the steam is re-condensed.  This re-condensed steam is distilled water.  This same process can be applied to other raw foods than have been fermenting to produce clear alcohol.
