Not sure if this is the right thread but since I am using an Electric BIAB set up why not.
Last brew my Voile bag created a vacuum of sorts. I was getting worried during mash out because the liquid level was moving from 6 inches (15 centimeters) to almost overflowing the pot. I was able to stop everything before it went over and when I pulled the bag away from the sides it seemed like it wanted to explode out of the kettle.
Anyone experience this kind of issue and any ideas why it happened and how to prevent it from doing so.
Thanks All

Do you mean the wort between the bag and the side of your kettle was moving up?

Yes!
I also got a reply on another beer website that said a too fine crush on a Braumeister system will cause the same kind of vacuum issues. So I think I am going to go back to a coarser crush or a malt conditioning process to avoid this in the future. It's pretty scary when you think 10 gallons of hot wort is about to explode out of the kettle.
