Abstract
A method of treating wine, comprising introducing crude wine to both the dilution and concentration chambers of an electrodialysis apparatus; operating said apparatus so that the potassium concentration of the wine in the dilution chamber falls to below 500 mg/liter and the potassium content of the wine in the concentration chamber is increased into the range 1000 to 2000 mg/liters; cooling the wine from the concentration chamber to below 10.degree. C and adding tartaric acid crystals to said wine in order to adjust the pH into the range of 2.8 to 3.2 thereby precipitating tartar; separating the tartar from the wine and admixing said wine with wine emerging from the dilution chamber of the electrodialysis apparatus in a ratio such that the potassium content of the resulting mixture is below 500 mg/liter.
