Quick Water Requirements
Water Gallons  Quarts
WARNING: Boil kettle capacity (12 gal | 48 qt) exceeded. Volume required: 33.18 gal (132.7 qt). Suggest reducing initial water volume to 12 gal (48 qt) and adding 21.18 gal (84.7 qt) sparge/top-off.    
Heat water added to kettle (equipment estimates 39.93 g | 159.7 qt) 43.05 172.2  
Mash volume with grains (equipment estimates 39.93 g | 159.7 qt) 47.37 189.5  
Grain absorption losses (steeping) -6.75 -27  
Pre boil volume (equipment estimates 33.18 g | 132.7 qt) 36.3 145.2  
Boil off losses -1.88 -7.5  
Hops absorption losses (first wort, boil, aroma) -0.3 -1.2  
Post boil volume 31 124  
Going into fermentor 31 124  
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.
