The ions in brewing water have two main effect with regards to the beer making process. First, in conjunction with the grain bill, the ions determine the pH of the mash. This is extensively discussed in earlier posts on this blog. However, the overall ion content of the brewing water (used in the mash and for sparging) also affects the flavor of the final product. It is thus desirable to keep track of the total ion content in one's brewing liquor. The update to my brewing spreadsheet, MpH Calculator v1.1, now allows the homebrewer to easily keep track of the overall ion content of the water going into his/her beer. Enjoy!
