Doing a 30L wash with 60-40 corn to malted barley and have found the wash stuck at 1.02 after getting off to a good start from an OG of 1.064
Putting the stall down to pH which I measured at 3.05
Having had this problem with a TPW wash a while back and using sodium carbonate to get that one working again, I bumped this AG wash up to mid to high 3's with 80g of sodium carbonate
Now reading into it a bit more I am worried I may have spoiled this wash as I've read elsewhere that sodium carbonate is not to be used for whiskey.
Have I ruined it? What kind of flavour (or other) problems can I expect once it ferments out dry and I run it?
Thanks

Get some pickling lime and add a teaspoon at a time until it gets up to about 4.0. Stir and wait at least 15 min between additions.
Sounds like your water has very little buffering capacity.
BTW, are you sure it's stalled? Maybe just slow.

You should really read this, and do so with the mentality that it is sarcasm: viewtopic.php?f=7&t=86962
The short answer is let it be, or run it as is. It's fine.

If it doesn't take off you might try pitching some D47 yeast. I have found it to take acidic environment better than most

Re: Have I ruined my wash?
Are you using oyster shells? They seem to dissolve as needed when the ph drops, keeping it up enough to keep the fermentation going.
Re: Have I ruined my wash?
Thanks everyone for your replies. It did start bubbling away again very slowly after a day or so. Haven't ran it though the still yet, so time will tell as to whether the flavour has been adversely affected.
I've started adding a handful of seashells to my fermenters now, hopefully this will assist in buffering the pH in future.
Cheers again dudes.
