I guess it's safe to say that you've found out the hard way why we say "no plastic" in the distillation process.
At least this isn't going to be a lesson that's forgotten any time soon.
-learned many things like this the "hard way."
Thanks for getting back to me. I haven't done this in thirty five years. Back then, everything
was copper or brass. I upgraded my old still to stainless and found out the hard way that you
need some copper in the process. The first batch smelled like old f**ts from all the sulphur
dioxide. Added copper mesh to the column and it cleaned right up. Didn't read the warnings
about no plastic. Yep, learned the hard way once more.
