Mineral salts to dissolve in reverse-osmosis or distilled water, calculated by the BrewWaterSolver solver with the most common homebrew salts.
| Salt | 5 gal (18.9 L) | 20 L |
|---|---|---|
| Calcium chloride (CaCl₂) | 0.19 g | 0.21 g |
| Epsom salt (MgSO₄) | 0.66 g | 0.70 g |
| Chalk (CaCO₃) | 5.11 g | 5.40 g |
| Baking soda (NaHCO₃) | 0.28 g | 0.30 g |
Closest match with these salts; it can't reach Mg 4.5 mg/L vs 20, HCO3 343.3 mg/L vs 389 exactly.
Chalk (CaCO₃) doesn't dissolve well directly in mash or sparge water without dissolved CO₂ - slurry it in carbonated water (e.g. sparkling water) before adding it, rather than mixing it into still water or sprinkling it in dry, or the calculated amount may not fully dissolve.
