Abstract

The present disclosure relates to a method for reducing water consumption in tartaric stabilization of wine by electrodialysis, comprising the following steps: passing an aqueous stream comprising a weak organic acid between a tank and an electrodialysis module; feeding the electrodialysis module with a stream of wine to be treated so that potassium bitartrate or calcium tartrate pass from the wine to be treated to the aqueous stream which flows between the tank and the electrodialysis module, so that during the passage of the aqueous stream through the electrodialysis module, the potassium bitartrate or calcium tartrate initially present in the wine stream are transferred to the aqueous stream and discarding the aqueous stream when it reaches a certain potassium bitartrate or calcium tartrate saturation point.
