The mash PH tool is used to calculate water adjustments based on a measured pH to achieve a target pH. Lactic acid, phosphoric acid, and acid malt may be used to adjust your mash pH to achieve a desired pH (typically in the 5.2-5.6 range)
A similar calculator is built into the mash tab of the recipe design suite.

Using the Mash Adjustment Tool
o | Select the Mash PH Adjustment Tool from the Tools menu or ribbon. |
o | Enter your mash water volume, total grain weight in the mash, sparge volume and sparge water pH. |
o | From the water profile of the mash water used enter the Bicarbonate figure which will drive alkalinity in the mash |
o | In the next section take a pH measurement of the current mash pH and enter your target pH. Note that the acids listed can only LOWER your mash pH and not raise it. If you are in the unusual situation of needing to raise mash pH, you may need to look at other mineral additions. |
o | Select the type of acid you want to use to lower the pH and the acid concentration |
o | Once you are done the Mash Acid Amount will show the proper mash acid addition to achieve your target pH and the Sparge Water Acid field will show the sparge acid addition needed to maintain a proper sparge pH (avoiding excessive tannins). |
