what %age of 4litres turns into alcohol

Roughly out of a batch of 23litres tripple disstilled alcohol how much 55-60% can you get from a still spirits air still.
Im getting around 700ml to 750ml around 60% is this right from a 4l fill !

hi scrappybill,

i dont use triple distilled, usually alcotec vodka star and now alcotec48, and i take at least 800ml to get 60%, infact when i did my last alcotec48 wash i forgot to set my timer to switch it off and when i came in from the garden i had 1400ml and it was still 50%, it smelled and tasted ok so i put it in the demijohn with the rest. try experimenting a little to see what you can get from your wash, you can always put it back through if you dont like what you\'ve produced.

cheers, hoppin

Interestingly I am finding the same. I was getting a completed wash at 14% which gave me an easy 800ml at 60%. the last couple of batches have not achieved that and I am not sure why.
First notices a vodka star batch ws not as strong as expected and thought perhaps I have made a mistake with the sugar. Then ran a Alcotc turbo and the wash was weaker than expected. All brewed out SG down at 970-980 so not sure what is going on.
With the weaker wash you obviously get less at 60% and that number seems to be about 700-750.
Buggered if I know what is going on.
Vodkas star wash in process at the moment for a reference.
Thought I would try the bakers yeast approach too

2nd 350mL 54 57 55 54 56 56 56 55 56 60 60 62 63 62 63 55 57 57

3rd 350mL 38 40 35 42 40 40 40 42 40 46 47 51 47 51 51 42 42 45
Double - 4 Litres (approx)
1st 350mL 85 83 82 82 83 82 82

4th 350mL 82 78 79 79 73 76 74

5th 350mL 80 65 75 75 -- 65 63
cut to new bottle and add to next distill.
6th 350mL 76 -- 67 67 -- --

7th 350mL 68 -- 50 50 -- --
(some of the readings were lost in the fog of battle)
