I would like to do a small batch of Highvoltagemans PA in my Anvil Electric. Seems like it is a good idea to do it BIAB style to use up the dead space there would be with the basket. Sorry if it has been discussed but I didn't see it. But.. When using a bag, if I want to raise my mash temp in setps, do I need to use some kind of false bottom to keep the bag off the bottom to keep in from scorching?
