Make a birdwacher's. Run 5 times 4 liter, tossing the first 50 mls on each run. Collect 1.3 liters for every 4 liter charge.
That gives you 5 times 1.3 liters is 6.5 liters at around 35%.
Add water to get to 8 liters. Now distill this 8 liter in two runs again. And again toss the first 50 mls on each run.
Collect like 1.75 liters on each run. You will end up with 3.5 liters of around 70% probably. Dilute to 30% and run a third time. On that run take carefull cuts.
You will end up with a pretty okay vodka that does not need filtering. Well, when I was still using my airstill and using turbo's that is what worked pretty well.
But, reading your posts, I would advice you to first read the parent site and then read much more on this site. Especially on pot distilling and making cuts.
