After doing a vinegar clean, and repeating the sacrificial run (because I forgot the vinegar run last time - at least I had the cheap vodka to reuse from the first one), I did the first two stripping runs from my 20L mash yesterday, in my copper alembic.
I think they went well. But before I talk about those, I want to check about something I observed after the first run - a bright orange deposit, particularly in the parts of the pot above the fill level. Reading around the forum a bit, I decided it was likely the formation of patina on the copper (http://ww.homedistiller.org/forum/viewt ... 15&t=61178" onclick="window.open(this.href);return false;" rel="nofollow).
But I was surprised it came off so readily on my fingers & a paper towel, when I was rinsing out between runs (bit of puking on the first). So I just wanted to check to be sure, last thing I want to do is give myself copper poisoning (though the color of the distillate does not suggest copper contamination).
