I just finished my second spirit run of UJSM on my pot still. With both runs I have collected down to 40%. Instead of saving my feints for an all feints run I would like to add the feints into subsequent spirit runs. I was worried that by doing it this way i will keep getting more and more jars of heads/tails. I think HDBN answered my question in the other thread.
So what HDNB is saying is when I toss the fores and the late tails (everything lower than 40%) it is removing all the excess heads/tails that were added from the feints so there isn't a "build up". Am I understanding this correctly? So it is okay to keep recycling my feints (both heads and tails) into future spirit runs?HDNB wrote:on the heads and tails in your feints jar...the heads do contain a higher% of lower alcohols, and the tails do have flavourful oils in them. But in lower proportions than what you started with, so the next run through will clean more and add flavour.
what i mean:
a 10% wash has 100% of the crap you want gone in it. when you toss the fores, a large percentage of the lower alcohols go with it and a large percentage of the higher alcohols (fuesal oils etc) are left behind in the boiler.
this is the the part your are neglecting: when you take a high ABV feints and dilute it with water or fresh wash, then take even more fores off and leave even more fuesals in the boiler
crap does not "build up" with each run, it is concentrated and removed from both ends of the run.
My other question is, should I be collecting lower than 40% on spirit runs? I stop there because it takes so damn long to get there. I thought about cranking the heat up a bit once I hit the 40% mark so I can get to 20% faster. How low do you guys go on spirit runs? And do you adjust the heat once you know your hearts have been collected?
I should mention, I am not blending tails into my hearts as of yet, I am keeping it simple for now collecting only hearts and tossing everything else into my feints jar.
thanks,
