So I'm making high ABV alcohol with just plain sugarwash, high alcohol yeast and freeze distilling. I added chitosan and kieselsol(turbo cleaner) to clear it before freeze distilling but my yeast was still live so it did nothing. I then heat up the liquid to 65 degrees to kill the yeast and maybe evaporate any weird things. Something smells and tastes really off, while before it was drinkable and actually pretty pleasant, even though it was just fermented sugar wash. I'm curious as to why the heating might have caused this and if it's still salvageable by normal distilling. I might give up on freeze distilling and just get a normal still.

  • To clarify - is the 65 degrees here in centigrade? Could you clarify the "off" flavor, perhaps describe them a bit? – rob Apr 13 at 15:48
  • @rob Hi, yes, it was 65% degrees centigrade. I don't exactly know how to describe the flavor, it's somehow caramelish but gross in a way. When I get back home I will have another taste and try to go more in detail. – Andrei Muha Apr 22 at 16:55
  • welp, the 3 weeks it sat in a pot while I was away seemed to almost make the smell disappear, I'll guess shitty compounds oxidized. I risked it and added oak chips cause wood absorbs a shit ton of nasty compounds anyway so it might be salvageable – Andrei Muha yesterday
