Making a second batch of American Pilsner and substituting 2# quick grits for the 2# of flaked maize I used last. The grits seem to feel heavier in the bag, more dense. It got me thinking that grits might absorb more mash water than the maize?? If true I'd obviously need to add more water to my mash.
My original and new recipe has 9.5# grain and 2# adjunct. With the maize I used 8.25 gallons of water in my BIAB which yields 5.25 gallons in the fermenter. Do you think grits might absorb more mash water and I might need to add more initially?
