I'm not on here to argue. Everybody needs to do their own thing. I'm just saying that if you keep redistilling a product that has already been taken to azeotrope, you can't make it into, Supertrope ?
You can however change it back to a less than pure product with water, and the stuff that's stuck in the joints of your distillation equipment, and pull that off in the next round (or 50 rounds) of distillation, and extract some of those added impurities in the re-distillation process, that smells like a head.
You can even add things in that water that you can't get out at 88% like lime that gives your redistilling spirit a different mouth feel, that makes you think it is "more pure" but it's really more of a mask.
if you do however have a still that can make NGS better than NGS, I would love to see the specs.
All of that said, when we make a vodka out of wine, vs for example wheat, we control our proofs to the minimum of the legal requirement to intentionally leave flavor and aroma nuance in the product. To me, NGS is just too ordinary.
