50g tub of calcium carbonate

Precipitated Chalk (also known as calcium carbonate or acid reducing powder) is used to reduce acidity (raise the pH) in ciders and wines that are too acidic.

Start by dissolving 1/2 teaspoon per 5 litres in a small portion of the must and then mix the treated portion back to the cider/wine.

Retest (or re-taste) and add more if necessary.
