Potassium bicarbonate lowers acidity and precipitates part of the tartar. The calculator gives the dose for your volume and target acidity.
Approximate calculation using a simplified model: for designing equipment and process modes, consult a technologist.
How does calcium carbonate deacidification differ from potassium bicarbonate?
Calcium carbonate is stronger per unit mass but may leave calcium in the wine; potassium bicarbonate is milder.
The calculations are approximate: they help to assess the process and compare options, but do not replace a process design and trials on a specific raw material. This section is for reference only and contains no commercial offers.
