I could use a hand tweaking my equipment profile.
I am using a single-vessel BIAB system, and the way I currently have it set up, after the mash I always need to add about 1/2 gallon of water to the kettle to hit the right pre-boil volume. I have been doing a quick and dirty cold water pour-over sparge to make up the missing volume.
This works OK, but I think I will get better results if my calculated water volume is a half gallon more than it is now. I would also like to skip the sparge step entirely.
I know I could just add a half gallon of water to my batches, but I would prefer that the Beersmith math is correct instead. What is the best way to accomplish this?
Here are some of my settings.
MASH TUN ADDITION is 4 gallons. This is equal to the approximate recoverable space under my mash screen.
LAUTER TUN LOSSES is set to 0 since I am doing BIAB, and the only water lost is whatever the grain absorbs. If I increase this number, so does Beersmith's total volume needed increase, but then my volume isn't tied as much to my grain amount.
LOSS TO TRUB AND CHILLER is set to 0.4 gal. This is about the amount of wort left in the kettle after pumping into the fermenter--the pump pickup is just above the bottom of the kettle.
BIAB GRAIN ABSORB is set to .496 fl oz/oz instead of the default .586. I did this long ago after I set up my current system, but maybe this needs to be tweaked. To get an extra 1/2 gal in the kettle I need to increase this value FAR above the default .586 though, so I don't think this is the way forward?
BOIL OFF is a very reliable 1.33 gal/hr.
Any ideas? Thanks for the help!
