On my last brew, I was planning on double batch sparging. I pulled 3.5 gals out on the first runnings, was targetting 7 gals pre-boil. Double batch sparge was then 3.5gal/2 sparges, so 1.75 gallons each. But that would have left me with a bunch of grain high and dry in the mash tun. Something didn't seem right, so just stuck with a single batch sparge so I could make sure all the grains were submerged when I dumped in my sparge volume.
I'm thinking I made the right call, but wondering if this is due to mash tun dimensions or what...or how exactly a double batch sparge would work, seems like you'd always be left with grains above the sparge water depth?? Am I missing something?
