Not sure if this is what you are asking, but a potstill that is relatively easy to build is quite capable of matching or exceeding the quality of most of the best liquors (not just ethanol) out there. The best single malts and (to me) best bourbons out there are made on potstills. Admittedly, the techno-stills (column, continuous, valved plated, reflux) make the job easier, more efficient in terms of time, energy, and ease of use, and expertise, but they don’t make the spirit better.
Of course, running a potstill takes some time, but it will never shortchange you with respect to liquor quality for fine spirits. On the other hand, if all you want is the ideal American vodka, simply ethanol and water, you really need a potstill.
