I was wondering if someone could help me out with some calculations. I am programming an application to use on my home brews and it works well for my single infusion... however, my double infusion calculations are off. For example, the first target temp is 156 and the strike water temp would be 168.48 if the grain temp is 73 and the mash thickness is 1.33 qts/lb and the grain bill is 15.
1st strike temp = (((((grain bill * 0.05) + ((grain bill * mash thickness) / 4) * 1) * target temp) - ((grain bill * 0.05)* grain temperature)) / ((grain bill * mash thickness) / 4) * 1);
I am just a little confused on how to get it from 156 to my next temperature for the double infusion. For example, if my 2nd temp were to be 165.. I am unable to recieve the correct strike temp. I believe that the correct calculation would be 166.35 and I got this by entering in the varibles grain temp as 156 and the target temp as 165. Not to sure what to do. I think I am probably over thinking this.
If you need more information, let me know. Thank you!
