Gratzer water profile

A pale, lightly smoked Polish wheat ale, tart and refreshing with a distinctive smoky character.

Target water for Gratzer

The target has a sulfate-to-chloride ratio of 0.8:1 (malt-leaning, balanced) - the balance that shapes how hoppy or malty the beer tastes.

IonTarget (ppm)
Calcium (Ca²⁺)60
Magnesium (Mg²⁺)8
Sodium (Na⁺)10
Chloride (Cl⁻)80
Sulfate (SO₄²⁻)65
Bicarbonate (HCO₃⁻)30

Water chemistry is highly recipe-dependent or the style is broad/historical. Treat this as a starting hypothesis, not a style requirement.

Brewing salt additions from RO water

Salts to add to reverse-osmosis or distilled water to reach this target, calculated by the BrewWaterSolver solver with the most common homebrew salts (calcium chloride, gypsum, Epsom salt, chalk and baking soda).

Salt5 gal (18.9 L)20 L
Calcium chloride (CaCl₂)3.01 g3.18 g
Gypsum (CaSO₄)1.16 g1.22 g
Epsom salt (MgSO₄)1.37 g1.45 g
Chalk (CaCO₃)0.13 g0.13 g
Baking soda (NaHCO₃)0.49 g0.52 g

Resulting water: Ca 63.2, Mg 8.1, Na 10.1, Cl 79.6, SO4 63.4, HCO3 30 ppm. Split the salts between mash and sparge water in the solver if you prefer.

Mash pH for Gratzer

With RO water and the salts above, a typical Gratzer grist is predicted to mash at pH 5.72, against a target of 5.30 (pale color - lower pH enhances crispness). To bring it down, add about 7.9 mL of 88% lactic acid for 5 gal (8.3 mL for 20 L).

Estimated from the style's typical color (SRM 3.5) without a real grain bill - enter your recipe in the solver for a sharper prediction, and always check with a pH meter.
