I made an oat stout on 8/09/10 which definitely got infected and got sour mighty quick. I got advice from the LHBS to use potassium metabisulfite to stop the souring, and kill any yeast left in there. I did it and added some cherries to the fermenter and let it sit... until today.
I was surprised at how well it turned out, the cherries come through well and they compliment the slight sour flavor.
The question is, how should I bottle this one? I realize that I have to re-pitch some yeast, but should I let it go and see if it starts fermenting again before trying to bottle it?
Here's the recipe if it matters
5 Gallon
2 lb. 8 oz. American 2-row
9 oz. American crystal 90L
4 oz. American black patent
8 oz. Roasted barley
1 lb. 8 oz. Flaked oats
4 lbs light DME
1/2 lb maltodexterin
1/2 oz magnum at 60
12 oz frozen tart cherries
