So, normal racking day, I'm putting my apple juice wine into a clean sterilized glass carboy. Throw in 4.5 teaspoons of bentonite to get her cleared up and start racking my mostly fermented wine (OG 1.090, SG now at 1.000) on top of it.
Halfway through the siphoning, I remembered I wanted to put some oak in to condition it and should have put that in the bottom. 'no prob' says me, I'll put it on top and wash it Down with the juice I plan to top off with. Apparently this was a bad idea.
The thing started fizzing like a science project volcanoe and spewing like a freshman in rush week. Well as wifey isn't too fond of wine spewing all over her floor, I shove a bung in it (bad idea #2).
So I go to grab some tubing to make a blow off hose and come back just in time to get a bung in the forehead, wine and oak chips in the eye, and a very unhappy wife.
What the hell happened?
