Hey, I need some advice here. A group of us filled up a used whiskey barrel and just bottled it up a few days ago. There was some white layer on top of the beer, and now I see it in my bottles already too. I think it is Acetobacter. Now I think it got in there and grew like crazy because we did not have the barrel completely full. (First time using a barrel) So, now we won't to make another batch and fill it all the way up and keep it topped up and all that. I know that you can't kill bugs completely from a barrel, so should we not use this barrel again? What is the best way to kill some of the bugs in there?
