Green or yellow for the first 1-2L
Posted: Fri Dec 30, 2022 11:01 pm
I have been battling green and now yellow coming out the still on the fore's and the first few bottles.
I have done 12 TFFV 200L mashes total and the last 3 have all had the same problem except for #12 was fine for 2 runs and went yellow instead of green on the third run. Where as Mash #10 and #11 bother were green for the whole 3 runs.
I had the issue a while ago. I was getting a green tinge on all fores and maybe the next 500-1000mls it slowly tapered away to not being noticeable by the end of the run.
I cleaned the still and still had the issue. ran a different mash and was all good so its not the still.
Narrowed it down to 2x 200L TFFV mashes I done. I put it down to putting eggshells in there and reusing some of the backset. I had let them both sit for quite some time before running.
fast forward to today. I had done a TFFV 200L and already ran 2 runs through the still last week no problems but the third run was yellow. the still hasn't puked, Is recently cleaned and no signs of corrosion on the copper.
the bubble plate looks clean as and the reflux looks clear in the bubbler.
I'm at a loss as the last TFFV I made was fine for 2 of the 3 runs so makes me think something is happening in the wash once its done.
ran some through my alembic dome that I had just put some wine through with no problems and had the same issue. so its not the still and has to be something changing in the mash itself?
Is there something to do with the PH causing it or what?
Has anyone had green or yellow distillate?
anyone got any ideas?
