If you wish to decoct a certain mass of the mash and have the calculator to tell you the temperature the decoction should be when added back, skip this field and enter a value in the Decoction Weight field. Enter the Decoction Weight. This is the mass of the mash that will be decocted and added back to the mash to reach the indicated final temperature. Changing this value will cause the Added Temp field to be recalculated. The calculator should now be indicating the Decoction Weight and the Added Temp required to hit the Final Temp.
Formulas Here are the formulas used by the Mash Temp Calculator.
The units used in these formulas are irrelavent so long as they are consistant. The following formula will compute the final temperature of a mixture of two masses at different temperatures. The following formula will compute the mass of initial strike water required to hit a certain mash temperature based on the temperature of the initial strike water. The following formula will compute the temperature of the initial strike water required to hit a certain mash temperature based on the mass of the initial strike water. The following formula will compute the mass of the water required to boost a mash from one temp to the next.
