WARNING: Boil kettle capacity (12 gal \| 48 qt) exceeded. Volume required: 13.44 gal (53.75 qt). Suggest reducing initial water volume to 12 gal (48 qt) and adding 1.44 gal (5.75 qt) sparge/top-off.

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.
