So I tried to carb a keg by using sugar to prime it. Somehow I screwed up. I went to tap the keg and it is just foam. I can't release the pressure through the pressure relief valve because just beer comes out. I put it in the keezer to chill it hoping that would settle it down a little. I don't have gas hooked up and it just spews foam out of the tap. I think my only option is to just keep pouring beer out of the tap until the foam gets low enough to release the pressure. Any ideas?
