American Light Lager water profile

A very pale, light-bodied American lager built for maximum drinkability, with minimal hop or malt character.

Target water for American Light Lager

The target has a sulfate-to-chloride ratio of 0.7:1 (malt-leaning, balanced) - the balance that shapes how hoppy or malty the beer tastes.

IonTarget (ppm)
Calcium (Ca²⁺)40
Magnesium (Mg²⁺)5
Sodium (Na⁺)5
Chloride (Cl⁻)55
Sulfate (SO₄²⁻)40
Bicarbonate (HCO₃⁻)10

Water target is a strong practical fit for the style family. Use as an RO starting point, then verify mash pH from the actual grist.

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)2.03 g2.15 g
Gypsum (CaSO₄)0.74 g0.78 g
Epsom salt (MgSO₄)0.80 g0.85 g
Chalk (CaCO₃)0.02 g0.02 g
Baking soda (NaHCO₃)0.15 g0.15 g

Resulting water: Ca 41.8, Mg 5.2, Na 5.1, Cl 54.8, SO4 39.3, HCO3 10 ppm. Split the salts between mash and sparge water in the solver if you prefer.

Mash pH for American Light Lager

With RO water and the salts above, a typical American Light Lager 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 2.5) without a real grain bill - enter your recipe in the solver for a sharper prediction, and always check with a pH meter.
