Quick Water Requirements
Water Liters
WARNING: Boil kettle capacity (45.4 L) exceeded. Volume required: 135.95 L. Suggest reducing initial water volume to 45.4 L and adding 90.55 L sparge/top-off.  
Heat water added to kettle (equipment estimates 161.5 L) 161.4
Mash volume with grains (equipment estimates 161.5 L) 178.3
Grain absorption losses (steeping) -25.5
Pre boil volume (equipment estimates 136 L) 135.9
Boil off losses -5.7
Hops absorption losses (first wort, boil, aroma) -0.3
Post boil volume 130
Going into fermentor 130
WARNING: Kettle losses > 2% detected which throw off OG calculation for extract/partial mash recipes in batch target 'fermentor' mode. Solution: Reduce kettle losses, misc losses and hops absorption in equipment profile, OR set batch target to 'kettle' and do a full wort boil. See batch target FAQ.
