Just the liquid.

I imagine a bag sitting on top of something (cake rack/cooling rack) with the spigot underneath the bag pulling the wort form there and returning the wort to the top of the kettle. Kind of a HERMS without the Heat exchanger.

Quick question about using the element during mashing. Anyone use a pump (I know it does add equipment and complexity) to recirculate the mash instead of stirring? Seems like that would work well in maintaing temps???

Howdy all, Been brewing BIAB for my last 7-8 batches. 15 years of brewing experience prior to that. I am now doing my best to spread the gospel to my club in Rhode Island!
