I’ve got some distillate and when I pop it in the freezer and winterize I notice it actually gets darker. The second pass will usually take cAre of it. But I’m curious if anyone else has noticed a winterizing oxidation reaction or something of the like?
And is there any controls for it?
Edit just had a thought, maybe its the mixing of the oil and alcohol in the presence of air? Any agitation would be adding oxygen into the mix in a now widely dispersed solution
