Brewing Water Chemistry Calculator
Water chemistry calculator for beer brewers targeting certain mineral levels. Converts salt additions to teaspoons. Calculates balance of flavor ions and checks for harmful levels.
- Enter your batch data in the first box.
- Water volume is all the water going into the mash, including losses and boil off. It is not the batch size or boil size. If you plan to have extra water left behind in your HLT, count that as well. 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).
- Find and enter your source water's mineral levels on line 4, tune target levels as desired (line 5).
- Add brewing salts as needed so the difference on line 8 reports all green values (within 20ppm).
- Watch for harmful levels as reported on line 9.
- Check the flavor ion profiles below for appropriate levels and adjust brewing salts if necessary.
- The water chemistry article at this site is a handy guide to understanding more about the ions.
