Hey Everyone,
I brew partial mash BIAB using a 5 gallon kettle: 2/3 grains to 1/3 DME. I typically mash about 8-9 lbs of grain in 1.35 qt/lb water, and then sparge with approx 2 gallons water to top up my 5 galloon pot to approximaely 4.25 gallons. I prefer rinsing the bag rather than the dunk sparge method.
How much sparge water is too much though? At what point does tannin extraction become a risk? I have experienced tannin astringency before, though attributed this to high mash pH, which is now under control. Just wondering if I should also limit the sparge water amount. All input appreciated!
