sentence: Pot stills are used for making alcohol like whisky.
sentences_after: A reflux still is much more complex. It works with a continual flow of liquid going into the boiler, and a continual flow of distilled liquid coming out. The distilled liquid can also be put through the process several times, which is why it is called a reflux still. This allows for a more pure product, and the person working the still can control the level of purity.
