They seemed to get me in the right direction, but something isn't totally there yet. I started with BS setting it up using /u/brulosopher's videos on youtube. I suppose if I got more accurate numbers I would leave kettle trub out. I don't have any losses from chiller or kettle trub, because I use an immersion chiller, and since I always seem to be short on wort, I drain all of it into my fermenter. It feels like all of the accumulated settings in BS end up with a target, and because my result never seems to match, I don't know what was off, or more importantly, what was indeed correct in terms of my settings on BS. Maybe even the first part of all this is: I'm not sure what baseline to establish between the software's precision, and the variables that I can hone in on over time.
#Beersmith biab for mac#
but it feels hard to measure things like grain absorption, especially on a brew day. BeerSmith2, now also available for Mac and Linux users, fully supports BIAB brewing. My mash efficiency now usually sits around 77%-78%. Sometimes I get a little bit extra depending on the grains in my bill. I accordingly changed my constant in BeerSmith to 0.46238 and am now spot-on after some gentle squeezing of the bag while it sits in a colander. Strike: 325.1 fl oz | Remaining Wort: 301.5 fl oz | Delta: 23.6 fl oz Pre-Boil Target: 2.30 gallons | Excess Over Target: 0.0555 gallons / 7.101 fl oz | Total: 2.3555 gallons / 301.5 fl oz Is this correct Beersmith & the Brewers Friend web-tool show very. Strike Water: 2.54 gallons / 325.1 fl oz | Grain Bill: 3.19 lbs fine-crush / 51.04 ozīeerSmith BIAB Grain Absorption Constant: 0.5860 fl oz / oz grain The recipe calls for 3.2Ltrs of Strike water & 3.49Litrs of Sparge water. So, on my next batch I decided to measure my actuals so that I could determine my true BIAB grain absorption constant for my brewhouse: I suspected it was due to my finer crush which wasn't holding as much wort as a coarser crush that the BeerSmith constant was likely based on. 586 BIAB constant was throwing my volume measurements off, causing me to end up with excess in the kettle that would dilute my OG.
