Do you have a pot and a reflux still?
Is this the whiskey run? no curs prob explains why it tastes off.
Might be better off getting your head around the cuts process then re run it doing the run using cuts. As a bonus it would then be a higher proof so you can age it also.
Did you at least do a fores cut?
To filter fill it with 40% then just let it drip out. You will lose some good flavour also alongbwith the manky ntails.
You can filter out tails but you cant filter out heads as they are lighter/thinner substances.
viewtopic.php?f=57&t=2859Cuts are not that hard discard fores cut then collect in small amounts, per jar 150ish ml, then air overnight. Go back next day smell taste the jars keep the good ones discard the bad. Dont drink while doing cuts or you will most likely do a crap job Heads tastes like solvent tails kinda tastes like wet cardboard or like the smell of a wet dog.
Best of luck
