New and improved Mash Chemistry and Brewing Water Calculator. The pH calculation was removed from this calculator.Use canning salt, kosher salt, pickling salt, or pure salt - just make sure it is not iodized.Īvoid regular table salt because it is iodized! Yeast will not handle iodine well so avoid 'table salt' or 'iodized salt'.If your source water is high for a given category, the easiest thing to do is dilute with distilled water to cut down the mineral levels, then add salts to rebalance.Alkalinity (in ppm as CaCO3) = HCO3- x 50 / 61.If your water report specifies alkalinity or hardness as CaCO 3, multiply that number by 1.22 to get the HCO 3 - value. This calculator uses Bicarbonate (HCO 3 -) as the measure of alkalinity.If the calculator reports a harmful level, this means it is definitely harmful to the flavor of the beer, and quite possibly harmful to human health!.A low or high ion concentration is not necessarily a bad thing, such as the case of Pilsen water, where the target is practically diluted water, or the case of Burton on Trent where the sulfates are elevated.Above recommended brewing range, but not harmful.Within recommended generalized brewing range.Water Chemistry - Ion Levels (ppm or mg/L) The water chemistry article at this site is a handy guide to understanding more about the ions.ĭilute with distilled water to lower source ion concentrations.Check the flavor ion profiles below for appropriate levels and adjust brewing salts if necessary.Watch for harmful levels as reported on line 9.Add brewing salts as needed so the difference on line 8 reports all green values (within 20ppm).Find and enter your source water's mineral levels on line 4, tune target levels as desired (line 5).The idea is to get the input water for the batch to match the same conditions as the target profile (eg, as if you were using water from the river Trent). If you plan to have extra water left behind in your HLT, count that as well. Water volume is all the water going into the mash, including losses and boil off.Enter your batch data in the first box.Mash Chemistry and Brewing Water Calculator. NOTE: Our new and improved water calculator more accurately predicts mash pH and handles advanced features like acid and slaked lime additions: This calculator is good for basic water adjustments and targeting a flavor profile only.
