I hear you and I know that some aspects of the craft are overly hyped, like EC and the whole methanol thing making you go blind.
The reason for me linking the study about another run bringing EC down by 97% wasn't to fear monger but to highlight the fact that, even though EC has a really high boiling point, some of it is still coming over. How bad is that 3%? Probably nothing to worry about but I think it merits a foot note that boiling points are not the be all end all of separation by distillation.
The real issue that we were tossing back and forth, based on the second article iwine posted, was the fact, that under certain conditions, the benefits that copper treatment can have on a wash/wine/distillate might be undone with time or maybe with another run. At least that is what I seemed to be seeing.
The EC thing folds into that because we are talking about copper treatment and the fix for EC is another run, and if that nullifies the benefits of treating with copper, "dependent on how the spirit was produced", drinking without a follow-up run "may or may not be " fine but if it reverses the copper treatment then treating with copper can be a waste of time.
I have to say though that the difference is so noticeable that, at least in my opinion, it deserves a little more research.
