Mineral Comparison Chart
Example Data Table
| Beer Style | Calcium | Sulfate | Chloride | Flavor Goal |
|---|---|---|---|---|
| Pale Ale | 75 ppm | 150 ppm | 75 ppm | Crisp hops |
| Porter | 60 ppm | 60 ppm | 90 ppm | Soft malt |
| Lager | 50 ppm | 50 ppm | 60 ppm | Clean balance |
Formula Used
Residual Alkalinity: RA = Bicarbonate - ((Calcium / 1.4) + (Magnesium / 1.7))
Sulfate Chloride Ratio: Ratio = Target Sulfate / Target Chloride
Salt Estimate: Salt grams = Average required ppm change / mineral contribution × water volume
Mash pH Estimate: Estimated pH = 5.45 + RA / 300 + color adjustment
Acid Estimate: Acid ml = pH correction × grain weight × strength factor
How to Use This Calculator
Enter your total brewing water volume first. Add current mineral values from your water report. Then enter target values for your beer style. Add malt color, grain weight, target mash pH, and acid strength. Press calculate. Review salt additions, residual alkalinity, mash pH, and flavor direction. Download the results as CSV or PDF.

Why Brewing Water Matters
Water shapes beer flavor. It affects mash pH, hop sharpness, malt body, yeast health, and final clarity. Many brewers focus on grain and hops first. That is useful. Still, water often decides whether a recipe feels crisp, round, harsh, or dull.
Minerals and Flavor
Calcium supports mash enzymes and yeast flocculation. Magnesium helps yeast in small amounts. Sodium can round flavor, but too much tastes salty. Sulfate makes hop bitterness feel drier and sharper. Chloride improves fullness, sweetness, and mouthfeel. Bicarbonate raises alkalinity and can help darker malts.
Mash pH Control
Mash pH is one of the most important numbers. A common useful range is near 5.2 to 5.6. Lower values may create a sharper beer. Higher values can taste dull or rough. Dark malts lower mash pH naturally. Pale grists often need acid or low alkalinity water.
Salt Planning
This calculator gives practical salt estimates. Gypsum raises calcium and sulfate. Calcium chloride raises calcium and chloride. Epsom salt raises magnesium and sulfate. Baking soda raises sodium and bicarbonate. Use the numbers as a planning guide. Always weigh salts with a precise scale.
Flavor Balance
The sulfate to chloride ratio gives a simple flavor signal. A high ratio supports hop bite. A low ratio supports malt body. A middle ratio gives balance. This ratio is not the whole story. Total mineral level also matters. Very high numbers can taste minerally.
Better Brew Days
Good water planning improves repeatability. Save each result before brew day. Compare it with tasting notes later. Small adjustments can make large differences. Start with modest mineral levels. Then adjust by style, ingredients, and personal taste. Clean water creates cleaner beer.
FAQs
What does this brewing water calculator do?
It estimates mineral additions, residual alkalinity, mash pH direction, acid need, and sulfate chloride balance for brewing water planning.
Can I use this for all beer styles?
Yes. You can enter custom targets for pale ales, lagers, stouts, porters, wheat beers, and many other recipes.
Is the salt amount exact?
It is an estimate. Real water chemistry can vary. Use lab reports, precise scales, and pH meter readings for best accuracy.
Why does sulfate matter?
Sulfate can make hop bitterness seem cleaner, drier, and sharper. It is often used in pale ales and IPAs.
Why does chloride matter?
Chloride can improve fullness, malt roundness, and smooth mouthfeel. It is useful in malt-forward and balanced beers.
What is residual alkalinity?
Residual alkalinity estimates how water resists mash pH change after calcium and magnesium effects are considered.
Should I always add acid?
No. Add acid only when estimated or measured mash pH is higher than your target range.
Can I download the results?
Yes. Use the CSV button for spreadsheet records. Use the PDF button for printable brew day notes.
