I have a 10 gallon pot that I plan on using for an E-BIAB vessel. It has a nice false bottom that was made for it that I was going to use to keep the bag off the element. My concern is that the false bottom sits at about the 2 gallon mark, leaving 2 gallons below the grain.
When calculating my mash thickness, would I need to exclude those 2 gallons? I.E. I have 13 lbs of grain that i want to mash at 1.25qts/gal. To do this, I would need 6 gallons in my pot (2 below the false bottom and 4 for the grains to swim in).
Am I thinking correctly on this?
