So, I won a 15g barrel in a competition earlier this year. I've brewed a RIS, a Wee Heavy, a DIPA, and a Brown Ale that all aged in the barrel. Following the Brown Ale, I figured I'd use the barrel for sour beers, but haven't had the time in my schedule to make a 15g batch to put in there. I boiled 15 gallons of water and put that in the barrel to sit until I could get around to it, but now it's been close to 2 months...and there is fuzz on then bung hole I can only assume it's mold...
Is there anything I can do to save this barrel, or is it pretty much done for? My goal is to use it as a sour barrel anyway, but not sure if it's even safe to use if mold is present in the barrel.
