First post here I am a fairly new all-grain brewer with around 4 batches brewed so far.
My all-grain setup right now consists of a 48qt Coleman cooler mash tun and a 8 gallon kettle. One of the equipment profiles in BeerSmith is a 7.5 gallon kettle and 48 qt cooler. Using this it shows a boil volume 6.41 gallons. I have had good results with this and always end up with right around 5 gallons of wort. I recently purchased a 5 gallon Igloo cooler with a false bottom which is another one of the equipment profiles in BeerSmith. Switching my recipes over to this new equipment its showing 6.0 gallons boil volume, maybe I am missing something but why would my pre-boil volume now be .41 gallons less just by using a new mash tun? My boil off rate shouldn't be any different.
