Mash Calculators
While searching for a handy free mashing calculator to guage strike temps, I came across this wonderful calculator. The formulae are from Ken Schwartz's Calculations for All-Grain Brewers, with the exception of the unit conversion calculations. The html code was written by Matt, the webmaster of the homebrew club The GreenBay Rackers.
These calculators should work as advertised, but use them at your own risk.
A special Thank You to Matt and Ken for their excellent work!
Strike Temperature Calculator
Calculate the temperature your strike water needs
to be in order to hit the desired mash-in temperature.
Rest Calculator

to raise your mash to the next rest temperature.
Can I Mash It?

hold your grain bill plus the strike water.
Note! This calculator does not take the
space under your false bottom into account!
