Re: Testing for Methanol?
- See Tony Ackland's site:
What he says: "A simple rule of thumb for this is to throw away the
first 50 mL (reflux still) you collect (per 20 L mash used), or
100-200 mL from a pot still."
Methanol has a lower boiling point than ethanol and will come out
first when the vapours start to condense. A reflux still "separates"
better than a pot still, that's why you should throw away more
distillate with a potstill.
