This [0] does not suggest that anything but ethanol/water and potentially some other volatile compounds are in the distillate. I'm not familiar with brewing and flavoring distilled spirits, but quite familiar with distillation and doubt that even oil would be in the distillate. [1] suggests that tannins are present in the distillate, but I have not found a tannin that is volatile and [2] names one that isn't in beer Flavor seems to be added after distillation from what i can see (and is potentially influenced by the volatile impurities) [0] https://www.compoundchem.com/2016/06/08/vodka/ https://www.compoundchem.com/2016/06/08/vodka/ [1] https://vinepair.com/spirits-101/how-distilling-works/ https://vinepair.com/spirits-101/how-distilling-works/
