So you want to determine how much hot water you need to add to your mash?
No Problem! Update the information in the table below to get your desired temperature.
Kettle water volume
Kettle water temperature
Step mash heating water volume
Step mash heating water temperature
Grain Correction Factor
pu (default value should be adequate)
Note: Grain temperature is assumed to be equal to the Kettle water temperature.
For initial mash in, set:
Kettle water volume = 0
Kettle water temperature = grain temperature
Step mash heating water volume = Water volume in mash tun
Step mash heating water temperature = Water temperature in mash tun
