I was using Bru 'N water today for an upcoming brew day like I always do and for whatever reason, I decided to double-check the ion concentrations against the values in the Palmer book, page 166 of the 3rd edition.
I'm brewing a 10 gallon batch of Amber ale. I'm building up off 100% distilled water. The target profile is:
Ca: 55
Mg: 10
Na: 10
SO4: 75
Cl: 63
Mash volume is 7.5 gallons and sparge water is 8.6 gallons.
After playing around with the ion concentrations, I was planning on using:
Salt: mash(g) / sparge(g)
CaSO4: 2.3 / 2.6
MgSO4: 3.0 / 3.4
NaHCO3: 1.1 (mash only)
CaCl2: 3.8 / 4.3
This gives me a mineral profile of:
Ca: 54.4
Mg: 10.4
Na: 10.9
SO4: 85.4
Cl: 63.8
Here's the issue: If I calculate what the ion concentrations are using the numbers from Palmer's book in my final wort volume, the concentrations come out significantly higher than what I listed above. If I calculate them based off the total mash + sparge volume, they match exactly. In other words, it's not obvious to me how to get Bru 'N water to give me the ion concentrations post-boil rather than the ion concentrations pre-boil.
I have the latest version (1.16).
Now obviously I'm missing something or doing something wrong. What is it?
