I'm getting about 85% efficiency while sparging. I use 1.25 qts/lb of water and typically do 60-90 min mashes at around 148-153. I fly sparge with about 4 gal or so of water until I reach my 7 gal of perboil water volume. On my last sparge, my final runnings were at 1.016
I know this isn't extremely high but I'd like to get down to 75% or so as I hear that there is the potential for tannin extraction and I typically try to make very clean and dry beers so this is an issue.
Should I just stop the sparge early and top off the kettle with pure water? Im wondering if that would help. When doea tannin extraction actually occur? Is is only in the final runnings? Or is there something I'm missing and maybe I'm not at 85% efficiency and miscalculating?
