Oh man, I did that last time and the next time I popped a cork, emptied the bottle on the ceiling. This time I'm going about it all differently.
Maybe you are suggesting I fill the barrel to the bung. I'll look into that though beforehand I sterilized it pretty thoroughly. After scrubbing it good inside, my favorite part was to put it back together and then burn a part of a sulfur wick in there. I couldn't hold my nose above the bung hole the fumes were so acidic. No bacteria were alive after that to get reactivated. That was my hope anyway. Since then it has been bubbling away, which seems a good thing. Thanks for your words of caution though, I will keep an eye on things.
