I have the Pro Series II that I used for distillation with the copper mesh packing. I used the 8kg Turbo Yeast and dextrose for fermentation with some of the distiller's nutrients found on the site. I fermented it for 3 weeks because I didn't have time to distill it. Once distilled, it has a very noticeable ammonia smell. Was the addition of the distiller's nutrients a bad idea since it has ammonium phosphate and some how that is breaking down? Also I am carbon filtering it and there is a section of the filter tube that is hot. It slowly is working it's way down the tube. Is that an exothermic reaction of the carbon with the impurities? I have made beer for years but this is my first time distilling. Any input would be appreciated.
