> think you can be sure that there in no methanol in your final spirit..I know that Mikes written that, and I've read it in a couple of other
places, but I'm still suspicious. I'd love to see a GLC run on some good
clean sugar wash, and actually know the concentrations.
It may not be methanol, but there is still something in the heads. I can
definately smell acetone (nail polish remover), if I let the column run
under total reflux for 15-20 min, then take off the heads dripwise.
Likewise in the temperatures - they still hang round below 78C until this
material is removed, so it is something different to ethanol.
Yoda - I'd still discard the first 50-100mL that you collect off a 20L
wash, just to throw away this first impurity(s). Even if its not
hazardous, it still tastes bad, and you don't want that corrupting your
nice clean spirit. Given that you're then going on to collect 3L+ of
spirit, its not a large cost for the peace of mind & ease on the tastebuds
Again - let your nose guide you - as you collect the heads, periodically
let a few drips run onto the back of a spoon, and give them a sniff. If
they smell bad - throw that portion away. If its agreeable, only then keep
