Cuts and separating fusel oils and volatiles
Posted: Sun Jan 21, 2018 12:10 pm
Hi Everyone,
I have been reading about boiling points of alcohols and how not to get them, first of all I would like to explain how I do it, and will move on to my question, I always do a stripping run in my capped ccvm still so I run it as a pot still in the stripping run, I collect the first 200 ml and discard it, then I run until I reach 30% ABV so at that point my boiler temperature reaches 98 and the vapour temperature reaches 97 first question as far as I read there is not a problem to go to that level since I am not making cuts but at the same time I am also introducing the propanol so my first question is ? Can I safely collect until 20%-30% in a stripping run, because in some threads it is said to collect until 95 vapour temp.
In the spirit run I dilute the low wines first and use my ccvm reflux still to distill, I collect in 250 ml vessels and air them for a day or two taste and smell them with equal amount of water and alcohol from each vessel and decide which ones to keep as hearts and feints at the end, this is my way to do it, but there is something that is not very clear even after reading tons of threads in here and the mother site, that is at first I am using a pot still and run it till the end collect everything then in the spirit run I use the reflux still, so in refluxing everything is much more compressed and unfortunately I cannot track the vapour temp correctly so I do not know where I am during the run only at the far end when the alcohol starts to depleted the abv decreases and the vapour temp rises very quickly at that point I am already done, so because of that is there a chance that I am introducing propanol in the hearts of course the idea of the cuts is to separate the volatiles and get the ethanol but for safety issues I am wondering if it smears in ethanol and if it could cause a build up and cause health issues, could you please read and comment if I am doing the right thing or maybe I am worried too much for nothing, it is just that I read some threads about propanol and other volatiles and wanted to be sure of, thanks.
