The mash salt additions calculator in Beersmith 3 seems to be really an improvement over Beersmith 2. Sparge water is typically between 2,5 L to 4,5 L. 18-19 L final beer after fermenter losses). I always mash with 25,5 L of water (I plan my recipes in this way) and Sparge with enough water to get to around 20-21 L Batch Size (= Volume into fermenter i.e. This setting (unfortunately not set in the Profile) needs to be changed in Tools - Options - Advanced: Grain Absorption and BIAB Grain Absorb. Notes - Here I record the value of Grain Absorption (GA) for the recipe. This way I leave a consistent amount of Trub (2,9 L) always in my Braumeister. In my setup I drain the Braumeister by setting a wooden block under the back foot of the Braumeister (in order to tilt it a bit forward). Loss to Trub and Chiller is the trub left in Braumeister. The total water volumes (Mash + Sparge) are off unless this is done! And if Cooling Shrinkage is set to 4% the OG will be off. This is to compensate the Cooling Shrinkage value of 0%. Mash Tun Volume, Weight and Specific Heat don't play any role with Braumeister.įermenter losses depend on your style of transferring the final beer (I hit a constant 1,8 L with my tubing). I use 70% to start with and then tune after first brew with a new recipe. I constantly hit all targets with the following Braumeister 20L profile:īrewhouse efficiency varies a bit. So, having measured mash water, sparge water, pre-boil vol, post-boil vol, trub losses, gravities etc. On average it is around 2,4 L/h in my environment, but varies between 2,2 L/h and 2,6 L/h. Boil evaporation varies a bit depending on climate (different in winter than in summer). Braumeister 20L rod top marker is 25,5L (not 25L) Also, I would hope that you could set the grain absorption value per Profile instead of having a global one! To overcome this limitation I just write the proper value in the Profile notes so that I remember to change every time. Like said, it is my empirical mean value based on 27 brews. This however depends on how you sparge, drain/squeeze the grain, etc. My empirical value is 0,017*grain-kgs+0,5973 (result is in fl-oz/oz). Grain absorption in Beersmith needs to be changed depending on the grain bill. I hope this would be finally fixed or somebody would explain why it behaves like it does. This needs to be compensated with negative (!) Mash Deadspace Losses value in BS profile, otherwise the water volumes don't match. I have had to set cooling shrinkage to 0% to get Post-Mash Gravity, Pre-Boil Gravity and OG to match spot on with my brews. Beersmith 2 and 3 both have a very odd way of calculating cooling shrinkage, or in fact its effect to OG. Here's my findings, feel free to comment/challenge! First with Beersmith 2 + different Excel sheets (Bru'nWater and BrewCipher) and now with Beersmith 3. I've done 27 brews so far with Braumeister 20L.
