As I work toward understanding my brewhaus efficiency (i.e. how well my sh*t works) I have run into an issue when figuring my needed water volumes.
Using the Water Needed worksheet in Pro Mash, when I have a 6.5 gallon recipe written out so that my grainbill is correct for my estimated efficiency at a volume of 6.5 gallons, am I wanting to have 6.5 gallons of wort in the kettle after flame out, or is that what I'm shooting have in the fermenter after transfer and cooling and such?
Seems that wort lost in the kettle due to deadspace or trub absorbtion is still PART of the 6.5 gallon formula when shooting for an O.G. of say, 1.050. Then you'll end up with, if trub loss equaled .5 gallons, about 6 gallons of hot wort, and then 5.75 or so gallons of fermentable wort. Am I making sense?
So I've got a recipe worked out at 6.5 gallons, OG or 1.050 at my 72% brewhaus efficiency. I know I lose .25 gallons of wort in the Mashtun and .5 gallons of wort in the kettle. Is it as easy, then, as going back to my recipe in Pro Mash (or whichever program) and locking my grainbill to my volume and raising the volume by the .75 gallons I know I'll be losing to equipment?
If so then I know why my last brew seesion yeilded a lower OG than I had designed it for!
