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)
