- Steps 1, 2, and 3b were taken from the recipe and your profile.
- Select the desired source water profile in step 3a.
- Add brewing salts or increase dilution as needed so the difference on line 8 reports all green values (within 20ppm).
- Watch for harmful levels as reported on line 9.
- Click the 'save' button at the bottom to store this information with your brew session.
Notes About the Ion Level Report:
- Within recommended generalized brewing range.
- Low, but not necessarily an issue.
- Above recommended brewing range, but not harmful.
- Harmful, do not brew at this level!
- A low or high ion concentration is not necessarily a bad thing, such as the case of Pilsen water, where the target is practically diluted water, or the case of Burton on Trent where the sulfates are elevated.
- If the calculator reports a harmful level, this means it is definitely harmful to the flavor of the beer, and quite possibly harmful to human health!
Notes About Alkalinity:
- This calculator uses Bicarbonate (HCO3-) as the measure of alkalinity. If your water report specifies alkalinity or hardness as CaCO3, multiply that number by 1.22 to get the HCO3- value.
- Alkalinity (in ppm as CaCO3) = HCO3- x 50 / 61
- If your source water is high for a given category, the easiest thing to do is dilute with distilled water to cut down the mineral levels, then add salts to rebalance.
Notes about NaCl additions:
- Use canning salt, kosher salt, pickling salt, or pure salt - just make sure it is not iodized. Avoid regular table salt because it is iodized! Yeast will not handle iodine well so avoid 'table salt' or 'iodized salt'.
