Potassium Sorbate solution 50% w/v (E202) (25kg)

Potassium Sorbate solution 50% w/v (E202) is brown solution free of particles.

Potassium sorbate is also known under the E-number E202 which is the potassium salt of sorbic acid.

Also known as a “wine stabiliser”, potassium sorbate produces sorbic acid when added to wine. This, in conjunction with metabisulphite, will inhibit the further growth of yeast.

Rates of Use

% Alcohol Sorbate Addition
10 % 0.20 g/l
11% 0.17 g/l
12% 0.135 g/l
13% 0.10 g/l
14% 0.07 g/l

Potassium sorbate addition is dependant upon several criteria including: Wine pH; Concentration of SO2; Percentage alcohol by volume; concentration of sorbate and viable yeast cell count.

Assuming the proper levels of SO2 are maintained and the pH is within the desired ranges, sorbate additions can be determined by the estimated alcohol of the wine.
