Yesterday I brewed a monster Imperial Stout with a gravity of 1.13 and Nottingham yeast. This morning it had filled half a gallon of overflow, so I increased the bucket size to a carboy with half a gallon of water. By late afternoon the carboy had 2 gallons of overflow liquid in there!
So, I didn't want to waste the overflow and decided to turn into a blackberry stout by adding 3-4 lbs of thawed and slightly cooked blackberries. I also plan on putting some oak and Jameson in the secondary for a full flavor. Kind of like bourbon county bramble rye...hopefully.
Has anyone ever recreated a brew from overflow before?
I had a small sanitation worry, but there was always a 2 inch foam layer, so I think the CO2 should have kept it sealed for the few hours.
Thinking outside of the brew kettle here...
