For drivin or for sippin, it all starts out as the same vodka out of the
still. One goes to the gasoline blender, the other into an oak barrel.

There's a micro distillery start up in this local, word is that it's
heavly regulated.
Their process is vastly different than a fuel plant. An
internal combustion engine doesn't mind nastys like aldehydes
and the higher alcohols, but I sure do. Oh I suppose one could
consider the fuel grade as a stripper batch and rerun it.
and I'm sure someone will do just that. ED

What's different about a fuel vs beverage distillery? I would expect they
would both be the same. Got any links explaining it? It seems to be an
issue not readily Googled.
Clearly some blindfold taste-testing is in order.

Start here-very good subject material
http://homedistiller.org/
" I heard about this guy" who actually built one of those,
reflux devices for,,well you know distilling essential oils,
or something like that. (really nice metal working project)
Seen pictures...copper is so pretty.when polished....
. The devil's in the details..yeast, wash recipe. ect.
After a number of attempts he's said really have it down to a science.
A good percent of what comes out is best used for ligher
fluid,(foreshots and tails) but the middle of the run or the heads
as its called is said to be pretty darn good.., esp. after a carbon
polish.
For fuel a vacuum system would be a good
choice. where as on a reflux type thing letting it relux
for a long while and getting it stabilized before opening
the drip makes for a nicer product, or so it's been said.
On a fuel system just strip it all out quickly...acetones, cogeners,
the whole thing...

I'm thinking chip relief/breaking. If any part of the chip contacts the
work, it will burnish a circle there.
Have you changed your tool or the grinding of it, or is it building a
false edge?
