I have a co pitch sour in the tank currently. I made the mistake of using OYL 011 as the yeast instead of my standard US 05 and it stalled at 1.041 when the expected FG was 1.027 (OG was 1.080). I'm trying to get it to finish. What I've done thus far...
1. Tried warming it up a bit.
2. Tried warming it up again and rousing the yeast by pushing a little CO2 in through the bottom dump port.
3. Added 5 packs of US-05 and warmed it up again to the max recommended temp for that yeast (75F). I did this on Wednesday night. No activity as of right now.
I know that I pitched that yeast into a hostile environment so I'm giving it till the end of the weekend before I call it and say that's not going to work.
My question: What are my other options to try and get this going again?
Now, this beer was going to get 20lbs of pureed fruit added after fermentation. I was thinking that MAYBE by adding that fruit and all that sugar, might kick off fermentation again. I know that's not guaranteed though and I could end up with a very sweet, fruited sour.
I also know I could make a large starter, let it get active and pitch that in. However, I question if that would work if pitching 5 packs of US 05 into 17.5 gallons doesn't work.
Any other ideas?
