However, calcium carbonate is more likely to affect the flavor than potassium carbonate, and may take a few months to fully precipitate. One-quarter ounce (about 4 teaspoons) of calcium carbonate reduces acidity in one gallon by about 0.25%. Foaming may occur because of the production of CO2. Do not use more than one ounce per gallon.
Calcium carbonate is an inorganic chemical compound made of calcium, carbon and oxygen with the chemical formula CaCO 3. It has a molar mass of approximately 100.1 g/mol. In an environment with normal temperatures and pressures, it has the appearance of a white powder that is fine in particle size and mostly tasteless and odorless.
