![]() ![]() 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. but it feels hard to measure things like grain absorption, especially on a brew day. With those two, your brew house efficiency will increase. Try to get a better mash conversion and take good notes to dial in your system. Don't chase a high brew house efficiency. With BS, you need to know your efficiency just because that is how he set it up to calculate volumes and gravity but it really doesn't tell you much. My important is mash conversion which is just calculating how much sugar can be extracted from the grains and how much actual sugar you extracted. ![]() For home brewers, we really don't care if we end up with an extra half gallon of wort that we don't use. Those take into account the loss within your system. You need to take really good notes and figure out your grain absorption, boil off rate, chiller loss and trub left in kettle.Īnother thing to think about is not looking solely at Beer Smith's efficiency numbers. They are there as a guide but are usually not accurate for your specific system. My mash efficiency now usually sits around 77%-78%.ĭon't use anything in BS as your own. 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. Pre-Boil Target: 2.30 gallons | Excess Over Target: 0.0555 gallons / 7.101 fl oz | Total: 2.3555 gallons / 301.5 fl oz 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 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. I feel like I'm getting a lot of liquid back. Then I put a bowl under it to collect during the boil and toss that in near the end of the boil. Right now I lift the bag out and hang it from a bike maintenance arm, and I squeeze it until it feels like I'm not getting much for my effort. I am wondering if this is where I am running into issues. I know that I could bump up my water by half a gallon for each brew, but I'd like to make the software more accurate by getting each setting right.ĭoes anyone know if the BIAB Grain Absorb setting in Beersmith is known to be pretty spot on? It's set to. Historically, I am ending up with less than that, usually around 5 gallons after the boil. ![]() I am trying to track down why I am getting around 50-55% efficiency in my BIAB process, as well as trying to dial in Beersmith's water calculations, so I reliably end up with the proper amount of wort (5.5 gallons).
