Hello everyone, today i changed to packing in my reflux still from stainless steel to lead free brass (essencia packing). I did my first TPW run through the essencia scrubbers and the highest ABV i got in the middle of the run was 89%. I know this isn't too bad but i was getting up 96% with the stainless steel, the only differnece i can think of is that i did have the stainless steel scrubbers packed mirginly tighter then the new one's. Would this be the cause to the 7% ABV difference?
Also on another note. What containers do you guys keep your feints in? I'm just using a Demijohn at the moment till it gets full. Just wondering what other people use.
Cheers
