The mash adjustment tool is used when brewing to adjust the temperature of the mash if it happens to be off by a little bit.  By adding cold water or hot water to the mash you can bring your mash back to its target temperature.

Using the Mash Adjustment Tool

oSelect the Mash Adjustment Tool from the Tools menu or ribbon.
oEnter your target step temperature - the temperature you want to hit
oEnter the starting conditions for your mash including the starting water volume, amount of grain currently in the mash and your starting temperature for the grain.  The starting temperature is the measured temperature of the mash before we adjust it.
oIf you want to also adjust for equipment - include a non-zero mash tun weight and mash tun specific heat.  Note that the mash tun specific heat is generally between 0.2 and 0.5, with all metal mash tuns being on the low end and plastic insulated mash tuns being on the high end of that range.
oIn the bottom section, enter the temperature of the water you are adding.  If you want to lower your mash temperature, use chilled or cold water.  Raising the mash temperature is best done with hot or boiling water.
oThe tool will show you how much water to add to achieve your target temperature as well as the final water to grain ratio.
