Re-distilling product

[bigjimbo]

Hi

I have a Stillspirits turbo air still and i have been sucessfull in its

use but I have a question maybe someone can answer for me.

In normal use of this still it says in the instructions fill to Gallon

mark run off 70cl although this contradicts in the write up with 80cl

so I run off 75cl.

Question is if you forget and run off more than the desired amount and

you have to do a re-run (2nd Run) how do you know when you have to stop

the run to avoid the impurities again.Is there a rule of thumb.

Obviously you would collect all the bad runs and put them through in

one gall lots but lets say you put in a gallon how much should you run

off in this gallon to achieve the desired alcohol I would imagine it

would be most of it.

I'm no expert at this only had my still a few days, but from what I gather its all about volume and math, Say you have a gallon of crap you need to re-distill and its at 50% in theory you could run it till you get half s gallon and get it to near 100%.
So the first thing you need to do is test your wash to find its ABV, then you can workout how much to draw off at a given strength.
If I'm wrong, someone please put us right.

You're right, but of course these stills max out at about 85% or thereabouts so you will never get the magic 100% and like you say, you need to measure what is going in and use the calculator to work out what will come out.
