i have been fermenting beer, cider and fruit wines for a while now and in a moment of madness in my local brew shop without doing any research i purchased a stil spirits air still and some turbo yeast and carbon filters. i know these have a bad rep on this board so please dont flame me! i simply didnt know any better!
after finding this board and doing some reading i realize a reflux still is probably the best option for me, but i am in a country where distilling alcohol is frowned upon
so getting hold of a proper pot or reflux still might be tricky/expensive so for now i am gonna stick with my air still, try to get the best out of it , and if anyone asks il tell them i only distill tap water because i like how it tastes 
This will most likely be my first and last turbo wash but i want to get the best out of it if you guys can help me a little! it is just finishing fermenting and will probably be clear and settled in a few more days, but yesterday i got impatient and wanted to test out my new still so i dug out some apple wine from the garage from last year that went a bit wrong and i didnt fancy drinking it so thought it would be a good way to test my still. It was pale, very clear and about 12-13% alcohol so i tossed it into the still and switched it on, threw away the first 50ml because it smelled and tasted like crap! then i kept the next 600ml, tasting it every 100mls and decided this was the point where i was probably hitting the "tails"
So... i got 600mls of 60% alcohol that i was fairly happy with, it was clear, alcoholic, tasted mildly fruity and was surprisingly smooth (much better than the failed wine it had previously been!). Overall it was a good learning experience .
Now, what should i do to get a good NEUTRAL spirit from my turbo wash? people on this board seem to hate the stuff and get bad smells and tastes from it...
here is what i was thinking of doing to it:
-let it sit for a good few days so all the carbon and yeast can sink away then rack it off
-let it sit for a few more days before racking again through filter paper on "distillation day"
-i have 24 litres of wash and a 4 litre still so i have to run it 5 times and was thinking of collecting 1 litre of hearts and tails from each run.
-then il take this spirit (which i am guessing will be at about 55%) and dilute it to 40% and run it through the still for a second time to clean it up further.
that last step is where i get myself confused... if i run 4 litres of a 40% spirit through my air still how much should i get out the other end and how strong will it be? im guessing it will be significantly higher than the first time (80 - 85% maybe?) how much liquid should i collect? should i just taste it as it comes and make a guess? what do you guys think? of course i will carbon filter it a couple of times once i have distilled for a second time to clean it up further.
