In any effort to increase my mash efficiency I’m wondering about my water ratios. Today I’m brewing a neipa with a 17lb grain Bill crushed on my mill set at .028mm. I’m mashing in with 7gal, 1.56qt/lb, I’ll get 4gal first runnings. Then I do a mash out/single sparge with 195deg water to bring the grain bed to 168-170deg, I’ll collect my remaining 3.5gal with that bit using a false bottom there always seems to be about 2gal left over that I dump before cleaning the mlt. Am I using to much water cuz I know u want as little wort left as possible. Should I do a 6gal mash with a 3 gal sparge or 6gal and 4 gal?? Just asking as idk how much this could really effect efficiency, maybe a point or two????
