![]() Partial pressure that corresponds to the CO 2 dissolved in the waterĪt 25 C (77 F). Kolbach defined residual alkalinity asĪlkalinity - calcium hardness / 3.5 - magnesium hardness / 7 RA or Residual alkalinity is the water’s alkalinity that has notīeen neutralized by the acidity created by the reaction between water’sĬalcium and magnesium and the malt's phosphates. That is how much acid is takes to lower its pH to 4.3 The water calculator implements alkalinity based on its definition and as a resultĭistilled water with a pH of 7 has an Alkalinity of 2.5 ppm as CaCO 3 since In brewing it is a measure of the water’s ability to raise mash pH. Hardness (GH p) is the difference between general and temporaryĪlkalinity is the acid eqivalents it takes to lower the water’s Hardness responds well to alkalinity reduction through boiling. Hardness (GH t) represents the calcium and magnesium that (GH): a measure of the calcium and magnesium present in the water To be off since that test does not test for 3 of the 6 major The water was entered as GH&KH it is usual for the ion balance Specified correctly and the user should check the water report. ![]() The ion balance is significantly above or below 0 it is possible that not Ion balance is the difference between the sum of cations Treated water before dough-in can be seen in the “Mash Water Reports only pertains to the source water that was specified. Note that the information shown in the source water For those interested an advanced water report isĪlso available. Knowledge ofĬalcium, magnesium and alkalinity is sufficient for predicting mash pHĬalculations” is clicked a basic water report for the source water Made and the sodium, chloride and sulfate ions are left as zero.īicarbonate will be calculated from alkalinity and pH. Known as Karbonathärte in German, hence the abrevation KH) anĪssumption about the relative amounts of calcium and magnesium is Only entered as GH&KH (general hardness and alkalinity, the latter is An accurate source water pH slightly improves mash pH prediction. Is assumed but if water pH is known it can and should also beĮntered. Specified as either alkalinity or bicarbonate. Latter is how sulfate is reported on a Ward labs report. Sulfate can be entered as ppm or ppm as S (ppm as Sulfate). Calcium and MagnesimĬan be entered as ppm (same as mg/l) or hardness (ppm as CaCO 3 orĭH). Report all 6 major brewing ions can be entered. A source water dialogĪccepts either a full water report or simple GH & KH Mash Water A, Mash Water B and Sparge Water. Source water dialog is shown, but up to 3 dialogs can be displayed: Jump to Water Volumes section Source Waterįor users with a Brewer's Friend account, water profiles can be configured here.Įven trial accounts benefit from this functionality. There is no support for blending different water sources to be used only as Sparge“ is checked only the mash water volume is considered for blending. By default the blended water volume is the The amount ofīlending water can be specified as % of water volume or absolute Shown and a source water dialog for Water B opens up. Waters” is checked a field for the blending water amount is ![]() In this case any non sparge water specific treatment will only apply to theĪlso be blended with a different water source. Sparge“ is checked a source water dialog for sparge water is shown. Useful for brewers who want to mash with their tap water and sparge ![]() To select a different water source for sparge water. Water volume is used for sparge water treatment. Volume will be used for the mash pH prediction while the sparge Requires removal of sediment (alkalinity precipitation through The total water volume might be larger than the combined mashĪnd sparge water volume. To mash water only all water treatment applies to the total water Water VolumesĮnter the water amount to be treated. The user should have a basic understanding of brewing water chemistry. It should be noted that this is not a guide to brewing water and mash chemistry. What follows here is a detailed description of how to use and interprete each These sections allowįor simple water treatment according to this flow chartĪ more detailes flow chart of all the calculator’s capabilities isĪvalable at the end: Full Water Treatment Flow Chart Only the most basic section are open on start-up. Get a report of the resulting water profileĬompare the resulting profile to a target profileĪll of these steps are done in different sections. The calculator’s layout is meant to be intuitive and follows the SO 4 2-/Cl - ratio: Total lactic acid as equivalent acidulated malt in grist: % ![]()
