Mash Chemistry and Brewing Water Calculator If you have feedback, positive or negative, please let me know: It will also allow the user to use saved source water profile(s). This will eliminate duplicate entry of the beer’s malt bill. target water comparison of the overall water reportįor now this tool is only available as a stand-alone calculator but Brewer’s Friend is planning to integrate it into the recipe editor.overall water report based on the mash and sparge water profile.Mash pH prediction based on balancing the various weak and strong acid systems that might be present (carbo system, weak acids and grist).Grist pH properties can be estimated from beer color or malt bill.Detailed report of the treated mash water.Sparge water acidification with a wide range of acids.Salt additions to sparge water or kettle.In most cases that might be reverse osmosis water when the tap water is suitable for mashing. A different water source can be used for sparge water.Salt and acid additions can be made to all water or only the strike (mash) water.Wide range of supported acids including the less commonly used citric, tartaric and acetic acid.These are features that rely on a more accurate implementation of the water’s carbo system Alkalinity reduction through boiling and slaked lime.supports all major salts (including magnesium chloride) as well as the hydroxides slaked lime and lye.Among the advanced properties are temporary/permanent hardness and CO2 partial pressure Report of basic and advanced water parameters of the source water.Simple GH&KH measurements can be used as a crude way of specifying the source water.Electrical balance (ion balance) of the source water.
pH can also be entered for increased accuracy
PHP, or any other programming language for that matter, makes that type of modeling much easier. This worked very well in its favor since it is very cumbersome to model complex systems in spreadsheets. Since Brewer’s Friend is an online recipe calculator the new calculator would also become an online tool. In fact the only calculator that goes to that extent is A.J deLange’s NUBWS (Nearly Universal Brewing Water Spreadsheet). The goal was to build something that provides a simple and intuitive user interface yet implements the underlying chemistry to at a level of accuracy that is generally not done in brewing water calculators. Since I have done extensive work on brewing water and mash chemistry already I took this as an opportunity to develop a new Mash Chemistry and Brewing Water Calculator from scratch.
When I started helping Brewer’s Friend as a technical adviser I couldn’t help but notice that the mash pH predicted by its brewing water calculator was way off.
