First 10L or so came out of my 50L stripping run v blue see pic. Tossed that and now it's mostly clear but still a little blue
I'm using a blue 220L blue bucket. Gave it a really proper clean before with percarbonate. It's been sitting for a while but it's foodgrade so shouldn't have leached into the liquid?
I didn't rinse the column out before the stripping run so maybe that? Doesn't explain why it's still got a blueiish tint.
Probably the copper.
And you should not use plastic with your distilate, if you do so, don't give your booze to anyone, nor should you drink it but definitely don't post it in here. It is not a safe material and doing so you are violating forum rules
If is the first time you use this still, you should first made a vinegar run, than a sacrifficial one. If you did not make it, save this distilate to do so, because it has already been sacrificed (as you put in plastic)
Copper sulphate most likely from dirty copper in your still, bin it as it is toxic (wont kill you but).. Empty and clean your still and packing with citric acid...

I've yet to encounter blue distillate, but here is a healthy discussion, from not too far back. It seems there can be multiple causes of blue distillate.
My experience is very limited. But I had some that I put in a jar and the blue eventually condensed on the sides above the distillate. I've also redistilled it and that removed the blue. It seems like I get blue booze when the pH of my wash is too high (basic side).
Had a quick Google and it's very inconclusive as to whether plastic will leach into the first run - especially at low Concentrations and a short time space like 6 hours?

The rules of the forum are quite clear on this though, no plastic contact with anything that comes out of the still.
For the record, the required testing for "food safe" plastics is leaching below a certain threshold at 15% abv (I don't recall the time frame). Your low wines will be between 20% and possibly 60% or more depending on the strength of the wash and how far you stripped. So you're always exceeded the tested capacity. In the end it's up to you, but even within the bounds of the testing, there's leaching occurring, just at levels that have been deemed safe.
Stainless and glass will both hold liquids without dribbling plasticisers and heavy metals into your proto-booze.

Big L ....65 posts and you still don't know not to use plastic? , and also don't know the forum rules ?
Suggest you start doing some reading before you continue .
If it's actually blue coming out of the PC it could be due to a high ferment pH reacting with nitrogen and copper in the still but yes the blue collection container is also suspect with high ABV ethanol solvent.
