Precipitated Chalk 100g

Beer making -Because of its limited solubility, it is only effective when added directly to the mash.

Use for making dark beers in areas of soft water.

Increase pH level.

Experienced brewers should monitor the mash pH with pH test papers to determine how much to add.


Wine making -Lowers acidity in wine.

Use  a mamimum of 1-2 teaspoons per UK gallon to reduce some excess acidity.

Using more runs the risk of allowing the wine to taste like chalk.

Best used in conjunction with acidity testing equipment.

Use before fermentation.
