This information is obtained through laboratory analysis. Because the mineral levels can shift seasonally or even day-to-day, it is recommended to monitor the overall minerality via [[TDS testing]], and it may be necessary to obtain a new analysis periodically. Analysis should ideally also be carried out over at least a one-year period to determine seasonal fluctuations.<ref name=eumbam>Eumann M.

Brewer's Friend has compiled a list of anaysis results: [https://www.brewersfriend.com/homebrew/water-profiles Source water profiles] (this page takes some time to load). If your water comes from a local municipal water supplier, it might provide a mineral analysis that includes the ions important for brewing, so also check there before sending a sample off to a lab yourself. Even if you are able to obtain a report this way, {{SITENAME}} recommends monitoring the TDS to ensure consistency because TDS testing is so easy and the meters are inexpensive. | ||
