Mash In: Strike Water Temperature
Mash In Strike Water Temperature Formula: SWT = (0.2/((SWV*4)/GW))*(DMT-GT)+DMT
- SWT = Strike Water Temperature (F)
- SWV = Strike Water Volume (Gallons)
- GW = Grain Weight (lbs)
- DMT = Desired Mash Temperature (F)
- GT = Grain Temperature (F)
Mash Out Water Volume
Mash Out Water Volume Formula: WV = (TT – CT)(.2GW + CWV)/(210 – TT)
- AWV= Added Water Volume (Boiling, but you will lose a degree or two, so we adjusted to 210 in the formula)
- TT = Target Temperature of the Mash
- Current Temperature of the Mash
- GW = Grain Weight (lbs)
- CWV = Current Water Volume (Water you have already added to the mash)
