Calcium Carbonate /CaCO 3 / forms carbon dioxide and precipitates calcium tartrate (). However, this introduces a risk of calcium tartrate instability. Simple deacidification with CaCO 3 is used against high tartaric acid content, mainly on grape juice/must, also can be utilized on young wines as well. Be careful with CaCO3 additions.

Precipitated Calcium Carbonate – Multifunctional

Production of Precipitated Calcium Carbonate Precipitated calcium carbonate is produced using the most economic process existing today. Limestone is converted into calcium oxide and carbon dioxide by means of calcination at temperatures in excess of 900°C. To ensure a high level of purity, the calcination process is carried out using natural gas.
