Just put the airlock on a carboy last evening on a batch of Chocolate Milk Stout. Nothing this morning, nothing at lunch, came home to a closet with fermentation all over the floor and my carboy and its still erupting. Obviously, I am cleaning it up but I would like to know my next step because I want to contaminate as little as possible.
Any tips or suggestions?
I cleaned a plug and a hose and I have it draining into a bucket.
