A method for tartaric stabilization, in particular for wine, and an apparatus for its implementation are provided. The wine to be treated is placed in a container and conveyed into a filtering unit. A permeated liquid is sent to a tartaric stabilisation unit for treatment. The tartaric stabilisation unit can operated by means of ionic exchange resins, electrodialysis or other separation processes. The treated liquid is reunited with a retained liquid at the outlet of the filtering unit to obtain a treated wine. Also provided are a cyclical operation of the apparatus and a cyclical method.

The present invention relates to a method for tartaric stabilisation, in particular for wine, and an apparatus for its implementation.
It is known that in wines, in must, in grape juices in general and in other drinks, potassium, tartaric acid and calcium are present in high concentrations. During the fermentation phase, potassium bitartrate, also known as tartar, is formed. Calcium tartrate can also be formed during the fermentation.
The wine, being therefore a supersaturated solution of potassium bitartrate, is subject to the precipitation of this salt. Similarly, the presence of calcium may constitute a further risk for the precipitation of the tartaric acid salt.
Further features and advantages of the invention shall become more readily apparent from the detailed description of a preferred but not exclusive embodiment of a method for tartaric stabilisation, in particular for wine, and of an apparatus for its implementation, illustrated in the accompanying drawing in which the sole figure FIG. 1 schematically shows an apparatus for the implementation of a method for tartaric stabilisation.
With reference to the accompanying FIGURE, the apparatus for the implementation of a method for tartaric stabilisation is globally indicated with the reference number 1.
The apparatus 1 comprises a container 2 able to hold a predetermined quantity of wine to be treated. The container 2 is provided with an inlet 3 and with an outlet 4. At the outlet 4 of the container 2 are operatively connected means 10 for conveying the wine to be treated to an inlet 21 of a filtration unit 20.
Advantageously such means 10 for conveying the wine can comprise connecting conduits 11 and a pump 12 for delivering the wine under pressure into the filtration unit 20.
