Blue Distillate Dangerous?

… Once diluted every jar would be crystal clear for a few minutes and then develop a haze that had a bluish tint when held up to the light…

I experienced this phenomena before with the distillate from a high corn ratio mash. The corn oils coalesced when cool and formed a cloud-like haze that had a very light blue color to it (when held up to the light).

The oil can somewhat be removed by filtering through a coffee filter (or two). Chilling the distillate before filtering also helps to get it out. But, keep in mind that the oils do contribute a lot of that “corn flavor” you’re desiring to keep in the spirit. If you’re going to age the spirit on wood, chances are that it will soak up the oils in the aging process anyway. So, filtering is just a matter for the obsessive-compulsive distiller (OCD).

I’ve also had blue flakes in low wines on some high ratio corn mash. The flakes are soft and appear fibrous - not crystal like. Not a ton of em and they float on top along with some oils.

Spirit run cleans it up for me.
