I have a stainless steel reflux still and I use filtered water ... Store bought grains and dextrose sugar
Next I monitor my still temp. and disregard all sprits up to 180deg. and shut down at 191deg. all is monitored by a computer I built. and wireless interface.
So I feel a carbon filter will strip all the flavor from the sprits and to me It seems wrong??????
Carbon filtering is used, in my opinion, to account for piss poor fermentation and distillation practices... A good wash, distilled properly, shouldn't require carbon filtering at all... Just added steps in the process that can be eliminated by doing things right the first time...
Not sure I agree with tossing everything below 180F, however... Would depend on the still design and wash being run...
Simple potstiller. Slow, single run.
