Heads and Tail help

[leob2]

I think I've got the heads figured out but I'm having trouble figuring out when the run is over. I know there is lots of info written about this subject but I need someone to spell it out in english,ABC,123. I have tried the "oily thumbnail trick" It still feels the same as in begining. I have stopped running at 202 degrees (I read that some where).
Just for example I set my 1st. quart aside. The next qt. was 180 proof and so was the next. after that the next 2 was 160 then the next 2 was about 140 and so on I stopped collecting at 120 proof should I have kept going or did I go to far or not far enough. How much hooch should I be able to get from a 15 gal keg

Seems most in a pot still quit catchin around 80-90 proof others higher.Uts really a matter of taste.As to how much hootch you should get out of a 15 gallon keg would be determined by several factors you failed to mention .Like how much wash was used proof of wash going in .What you really need to do is more reading. Would save you lots of trouble down the road if ya studied a little more. Good luck to ya

Here's how I determine when to stop collecting... I'm not greedy so I stop collecting as soon as I can no longer get a sample of a few drips, about 1/8 tsp, to burn... Not scientific, but it works for me... With my small experimental runs, about 8 liters, I'll usually start getting off smells and oils from the tails shortly thereafter anyway... For larger batches it might be worth collecting more but like I said, I'm not greedy...

I also use the "will it still burn?" method as a general guide. I'll hold a stick in the output stream for a second and then see if it will burn. I collect in pint jars when I know I'm getting close to the end of the run I'll start holding them up to the light. I usually get one that has small floating particles in it. That or a couple samples before is usually where I end up making cuts. Sometimes the jar will be cloudy looking, or I will get a series of jars that get gradually cloudy over two or three samples. That's how I'll decide to stop collecting. Making the tails cut is a different process.
