i made a batch of vodka the other month that absolutely destroyed grey goose or any of that other bullshit. you put it in your mouth, swirl it around, notice a faint tingle, drink it, think it was actually water or only distilled to 20% instead of the 40% it is, then fall on your back with your feet in the air like a drunk cockroach
any of the other distilling enthusiasts out there will tell you point blank that any vodka made from a continuous process (as per the fractionating columns they use to make commercial vodka) from non refined carb sources (like corn or whatever is cheap, as per commercial vodka producers) will retain more cogeners than a single batch process, where you keep the 'hearts' of the distillation and discard (or re-refine) the heads and tails
raw spirit made from refined sugar in cool conditions in large batches with only the hearts kept for on the rocks drinking absolutely SMASHES the commercial stuff out there.
