Claim:
A method for tartaric stabilisation of wine, comprising the following steps: a. Placing wine to be treated in an appropriate container; b. Conveying the wine into a filtering unit; subjecting the wine contained in said filtering unit to a nanofiltration process through a nanofiltration membrane, obtaining a permeated liquid and a retained liquid; c. Transferring said permeated liquid to a tartaric stabilization unit; d. Subjecting said permeated liquid to a tartaric stabilization step in said tartaric stabilization unit to obtain a treated liquid; and e. Reuniting said treated liquid with said retained liquid to obtained a treated wine wherein said tartaric stabilization treatment step is effected by treating the permeated liquid with cationic or an anionic exchange resin or by electrodialysis, thereby reducing the potassium or tartrate content of the permeated liquid.
