I am sure I am over simplifying this, but what I don't understand
I look at the water profile adjustment tab in Bru'n Water
Select 100% R/O water.
Set the "Desired Water Profile" as Burton
Then I am supposed to input different mineral additions to hit that profile?
I am sure someone has done this already?
So just tell me what to add to hit that profile?
Seems like you have a grasp on how to manipulate the software. Start plugging in values.
What you need to understand is that you should be targeting a certain mash pH, not mineral additions. Once you add in the grain, which will vary, it is a whole different ball of wax. Anyone can make the numbers match up, or at least somewhat closely match up, to what a city water report says.
As a starting point, plug in the grain bill and the water you are starting with. Start adding stuff to get the mash pH where you need it. Then start checking out the Sulfate to Chloride ratio to give it a round or sharp edge flavor-wise.
Isn't all that in the instructions?
