SY2425 POTASSIUM

Turbidimetic method for potassium measurement

Potassium is the most abundant cation in wine. Its concentration depends both on the grape variety, the soil conditions, the collection procedures (presence of scratches) and the methods used in winemaking. High values ​​of potassium in the grapes will lead to more basic musts, which could adversely affect the quality of the wine. Although most of the potassium salts are soluble, potassium bitartrate decreases its solubility as the concentration of alcohol increases, giving rise to precipitates that, although they do not affect the organoleptic properties of the wine, can be perceived as a decrease in quality.
