He stated that he preheats his tun. If he does that the calculations in ProMash will be pretty accurate.WBC said:There is no way one can say "use this temp" unless they are using the same mash tun setup that you are using and use it at the same ambient temp. You can get close using programs such as Pro-Mash or Beer Smith but you have to adjust once you try that temp to be able to hit that strike temp every time. Be sure to write down what you do every time so you can adjust for the next brew. Everything comes into play here. Grain temp, Mash tun temp, etc.
