Old Ale water profile

A strong, malty English ale, often aged, with rich dark fruit and caramel character.

Target water for Old Ale

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⁺)90
Magnesium (Mg²⁺)10
Sodium (Na⁺)25
Chloride (Cl⁻)115
Sulfate (SO₄²⁻)75
Bicarbonate (HCO₃⁻)100

Useful starting target, but recipe composition or regional interpretation can materially change the optimum. Verify mash pH and sensory balance.

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)4.38 g4.63 g
Gypsum (CaSO₄)1.25 g1.33 g
Epsom salt (MgSO₄)1.74 g1.84 g
Chalk (CaCO₃)0.59 g0.62 g
Baking soda (NaHCO₃)1.54 g1.63 g

Resulting water: Ca 93.9, Mg 10.1, Na 25.3, Cl 114.6, SO4 73.9, HCO3 99.8 ppm. Split the salts between mash and sparge water in the solver if you prefer.

Mash pH for Old Ale

With RO water and the salts above, a typical Old Ale grist is predicted to mash at pH 5.46, against a target of 5.40 (amber/brown color - balanced pH for malt character). To bring it down, add about 1.2 mL of 88% lactic acid for 5 gal (1.2 mL for 20 L).

Estimated from the style's typical color (SRM 15) without a real grain bill - enter your recipe in the solver for a sharper prediction, and always check with a pH meter.
