RE: [new_distillers] Methanol question...
- I only use sugar washs and,theoretically,they produce no/very little
Methanol.I do,however,toss the first 50ml on the first 'run' (of 12.5L)and
an additional 100ml on the second(usually a run of the distillate from two
12.5L runs combined)...after all,I AM drinking this stuff....:>)
