> I thought you had to use a column still to make vodka, and that if you use a pot still, it's basically (white) whiskey. a column, typically a reflux still, is generally what is used, yes. it provides a much higher alcohol concentration to be extracted in one single pass. at highest efficiency, you'll get 95% alcohol as a return. you can also make multiple (5-10) passes in a pot still to get the same purity, it's just nowhere near as efficient (because of the multiple runs).
