Hi, I have just done a spirt run with about 15L 50% low wines and topped up with 15L of 2nd gen macstill rum.
2" pelican pot.
Running at about 1-1.5L/hr, I was 9.5L in and I'm down in the tails, sitting at 50% all of a sudden I get alot of brown/black floaties come through, it's not the oils that float on top like I have seen down in the tails while stripping, these ones are small chunks suspended throughout my collection jar although very slowly settling to the bottom, there is also a few small blue/green coppery ones.
I collected one more jar after this and it has alot less than the first jar that showed any signs and the bits that did come through started settling alot quicker. This jar become very cloudy and I just started stripping into a stockpot from there too add to feints.
I fished some out and it is sort of grainy, reminds me of crushed up welding slag
What are these brown bits?? I won't be adding them when I blend but i am curious, what I can do with it or how to prevent it in the future.
PS. Pretty sure I got a bit overboard racking in the wash and got a small amount of sludge in the boiler before realising, thinking this might have something to do with it.
