I have just started to run my 3" copper packed column and am running the 5th spirit run today.....
I did many Teddy's strips and collected 5 litres of 48% and had over 100 L stored in 50 L beer kegs.....
It took a few reruns and some reading to get the still running right..
In "the Distillers Library " section page 2 there are 2 Pdf's on " Activated Carbon " and on page 3 a book called
Making Pure Corn Whiskey
viewtopic.php?f=47&t=1837 Distillation Principles page 69 is all about fractionating stills, but the best part for beginners are the calculated volumes..
This is a Guide For Beginners and you must use taste and smell for the final cuts
So my 23 L of 40% has 9.684 L of 95% alcohol "(23000 x .40 ) /.95 = vol of 95% alc in the still..
Fores 3.1% = 300ml
Heads 17.4% = 1685ml = total of 1984ml so discard 3 off 700ml wine bottles down the sink
Hearts 57.1% = 5529ml
Tails 22.4% = 2169ml
So start still
Reflux starts at about 83*c reflux for 30 minutes
Collect 700ml reflux 15 minutes another 700ml reflux 15min 3rd 700ml
Collect 6 jars of 250ml than 2000ml of the middle Hearts than another 7 jars of 250ml
Total at last jar is 7350ml just short of the Tails
All about 95% ABV
Water temp out between 37*c to 40*c
And the boiler is at 83*c at start and 93*c at last jar
But my runs are for Neutral
