slow evaporation



Why would you not be able to toss away methanol and fusels using the method presented in slow evaporation(http://www.amazingstill.com onclick="window.open(this.href);return false;" rel="nofollow)?
Could you not toss away the first litre of the spirits and thus throwing away a major part of the methanol? I understand you can't take away all methanol but at least this would help somewhat uh?

You can't cut the run from an evaporation still the way you can from a traditional still because everything is evaporating at the same time but at slightly different rates... the ethanol and methanol and various fusels evaporate at close to the same speed as one another while the water evaporates a bit slower but not so much slower that it doesn't wind up as more than half of the finished run.
unlike boiling in a traditional still you don't get cut points at the boiling temps of the various components because you never get much hotter than bathwater... the distinctions just aren't there, everything evaporates (slowly) all at once.

no methanol is produced in a sugar wash. if you are worried or want to get rid of heads then simply boil your distillate in a large stock pot for a few minutes to boil off the initial fractions just like in a pot still.

No methanol? none? Only place I've ever heard a claim like that is on Gert Strand's ad copy... Lots of people love Gert and still throw away the heads.

Re: slow evaporation [re: Fourway]



heads are mostly ethyl acetate not methanol.

"mostly ethyl acetate"..............methanol vs. acetate, isn't that like like compareing a 45cal to a .308, in either case your in bad shape

actually from what I can find online ethyl acetate gives an "off flavor" or "off odor" but doesn't have anything near the horrific destructive effects of methyl.

ethyl acetate is in many soft drinks and food as flavouring it can be bought in many shops as flavouring
