Odorless white powder or crystals, Mol.wt:100.11, specific gravity: 2.17.
Potassium bicarbonate (E-501) is a product deacidifying which modifies the pH and lowers the acidity. Added to wort or wine, it reacts with tartaric acid and produces potassium bitartrate which is insolubilized effectively.
During the harvest, as deacidifier of the must.
In white, rosé and red wines, to correct acidity during the elaboration process.
Potassium bicarbonate softens wines by giving greater harmony and balance while reducing their acidity.
Must or wine 0.2 - 1 g / l
The maximum deacidification allowed in wines is 0.65 g / l expressed as sulfuric acid (1 g / l expressed as acid tartaric), which corresponds to a treatment dose in potassium bicarbonate of 1.3 g / l. This product can be subject to declaration.
1. Potassium bicarbonate reacts exclusively with tartaric acid forming bitartrate potassium. This delay precipitates when using the cold stabilization process, which leads to a further decrease in total acidity.
2. When applied before bottling, will wait 4 to 6 weeks before putting the wine in bottle.
Dissolve beforehand in a part of the must or wine at process, then add to the total volume. Shake vigorously after 24 hours.
