Dry Liquor Salts Water Treatment DLS DWB 400g tub.

Before you can start to treat your water you should first contact your water supply company and request the total alkalinity of your water in p.p.m. Unfortunately this is not as clear cut as it should be. Water authorities usually express alkalinity as HCO3 (hydrogen carbonate) whereas the brewing industry uses the traditional CaC03 (calcium carbonate). To use the tables below you will need to know the alkalinity expressed as CaC03. As you will probably have only the HC03 value, you can convert it to CaC03 simply by dividing this figure by 1.22. From this figure it is possible to determine the required amounts of CRS and DLS to be added for all styles of beer. An average Bitter or Pale Ale requires the water to have a total alkalinity of 30-50 p.p.m. and a calcium content of 180-220 p.p.m. If the total alkalinity of your water is below 50 p.p.m. you will not need to use CRS but will most probably need to increase the calcium with DLS.

Example: You are brewing a Bitter and the total alkalinity of your water as CaC03 is 195 p.p.m. In order to bring it within the target range of 30-50 p.p.m. you will need to reduce the alkalinity by 145-165 p.p.m. From the following table you can calculate the amount of CRS to be added. N.B. All brewing liquor should be treated with CRS, not just that used for mashing.
