Oooooo.. Im stressing my memory back to chemistry at uni..
Different alcohols (And substances) will have different retention times. If I remember correctly.. chromatography? Pretty sure its the process of separating substances and then identifying them based on retention times. (Basically how long they take to fall through a tiny tube)
Not sure if theres any home kits that will be accurate enough to identify between the light and heavy alcohols.

Surely mass spectrometers are affordable these days?
Guess that depends on how much alcohol is gonna be brewed

Speaking of which. I tested my purge canister on the red VP to make sure it still worked and ethanol came out of the purge lol. Must of been from when I used e85 as the easy vaporization filled the canister or possibly 98 octane fuel contains ethanol in small amounts and that fraction evaporated and ended up in the canister? It was months of using 98 after only one tank of e85 ever being in the car so I can't imagine it hanging around for that long?
I'm the director of VSH (Vlad's Spec Holden), because HSV were doing it ass about.

The all grain tastes great but they said it takes 8+ hours to make and you need the equipment. I'm a consumer at the end of the day and kit and kilo is cheap and easy with great results. One day when I have time i'l do all grain

Yeah I tuned my VE S2 sidi 3.0L with a full tank of E85 6+ months ago & I still get a wiff of the ethanol from time to time especially on warm day when the recirc isn't on, that is also most likely worse as I have the breather system venting to atmos... but getting a bit off topic lol.
O.K. so now bringing this back up as I never did anything about it & my bday is coming up so might buy myself a pressie & have looked into the risk's & what not & so long as you get rid of the first 100ml(50ml is recommend by minimum) of each wash it should be a fairly safe process...
I did notice there are stainless kits & copper kits but have been told the copper kits are the same internally so it's really just for looks can anyone confirm or deny this or have other thoughts?
Copper helps with the taste, copper packing is also better but hard to maintain.
If your doing the grain spirits youll need a pot still, it keeps the flavor of the mash unlike a reflux that makes clean spirit.
"A friend" uses a pure distilling copper reflux still, it made about 92%, its since been modified with a double length head and two lots of packing and makes a very clean 96%
You could make your own reflux still, its simply a tube stuffed with packing and a cooling core at the top.
