Correct me if I'm wrong... But isn't brandy, whiskey and vodka consist of denatured Ethyl Alcohol?
If you make up a simple "still" to concentrate a few Liters of a well known Russian brand of vodka that is "filtered through charcoal seven times for purity", or perhaps contact the local "moonshiners" for a pure(undiluted) pint of their finest would be a lot cheaper?
