Calcium (Ca): mg/l or ppm 73.5 Enter value for Calcium from water report, e.g. 13.8 mg/l
Magnesium (Mg): mg/l or ppm 6.5 Enter value for Magnesium from water report, e.g. 3.38 mg/l
Sodium (Na): mg/l or ppm 17 Enter value for Sodium from water report, e.g. 10.5 mg/l
Sulphate (SO4): mg/l or ppm 104 Enter value for Sulphate from water report, e.g. 30 mg/l
Chloride (Cl): mg/l or ppm 26 Enter value for Chloride from water report, e.g. 12.5 mg/l
If your water report has a value for Carbonate (CO3), then enter that in the box below. If it does not specify CO3 then leave the box blank.
Carbonate (CO3): mg/l or ppm Enter value for Carbonate from water report, e.g. 13.2 mg/l
If you have not entered a value for Carbonate (CO3), but your water report specifies a value for Alkalinity "as HCO3", then enter that in the box below. If it does not specifiy a value for Alkalinity "as HCO3", then leave the box blank.
Alkalinity as HCO3: mg/l or ppm Enter value for Alkalinity from water report, e.g. 14.5 mg/l
If you have not entered a value for (CO3) or a value for Alkalinity "as HCO3", then either enter the value from your water report for Alkalinity "as CaCO3" or enter the value you have measured for Alkalinity "as CaCO3" using the sample kit.
Alkalinity as CaCO3: mg/l or ppm Enter value for Alkalinity from water report or sample kit, e.g. 11.9 mg/l
Next, we need to know what volume of water in total you will be using and what volume of water you will add to the mash:
Total volume of water: litres Enter total volume of water, e.g. 25 litres
Volume of water in mash: litres Enter volume of water in the mash, e.g. 10 litres
Now we know the composition of your water and what brew volume you will have, we need to know what sort of beer you wish to brew so that we can determine how best to treat your water. Please select the beer style below that most closely matches what you wish to brew.
General beer style: Select the beer style you intend brewing, e.g. Stout
Now we should have all the info we need to calculate what mineral salt additions you require. Please click the calculate button and then read the results below.
