Is corn mash at SG 1010 and PH 4 alright to distill, plus many other ways to
ask the same question but can't nail down an answer. All responses skirt around it.
I'm running two batches of 26 liters which I put down on the 27th. August, so 3 weeks ago.
My SG was at 1005 in one and 1010 in the other and stagnant and my PH was about 4 in
both so I pitched some more yeast to try and start it up again.
No change in SG though I did get some activity for a while but the readings remained the same.
So I added some calcium carbonate. This took the PH up to 6.1 in one and 6.5 in the other.
The SG then went to 1010 in both. I then poured both into a large plastic tub and stirred them
both together, this also aerated the lot extremely well, then divided the contents evenly back
into the fermanters. The airlocks went beserk for an hour then slowed down.
The last couple of days the SG has remained at 1010 at 21 deg celsius
in both and the PH has slipped back to 4.0 and 4.1 and no activity in the airlocks.
I've been trying to find out if fermentation has ceased and if these readings are good
enough to run through the still.
Appreciate any advice.
Cheers.
