Thanks Robert, I'll make a note of that.
Myles, good ideas, I really should take more notes... I will try stripping with a packed column next time and report back with results.
I retested the alcohol content tonight now the liquid is at room temperature and the meter (Stevenson Reeves LTD) showed over 95% and the yeasty smell I found before has gone, I think I had the smell in my nose from being in the workshop and somehow associated it with the product, it just smells clean now, kind of a clinical clean smell.
I'm going to do a run of kale wash next and do some blind testing to see if I can detect a difference.
I'm also going to start reading about making whiskey and pot stillin so if anyone has a link to any articles worth reading or recipes I'm all ears, I follow a chap on youtube, Still it
