Our Selective Tartrate Removal System uses electrodialysis technology to reliably remove tartrate salts from wine.

Winesecrets is the exclusive North American supplier of the mobile Selective Tartrate Removal System (STARS). The system uses highly selective ionic membranes and a weak electric field to remove the specific components involved in tartrate precipitation. STARS requires no refrigeration and can stabilize wine at rates of up to 1,600 gallons per hour. Benefits of STARS include:

• Energy savings: uses up to 95% less electricity than traditional cold stabilization.
• Fast: stability in a day vs. 2-3 weeks with traditional methods.
• Reduced wine loss: racking off precipitated tartrates can result in volume loss of 5%.
• Specific: treat only as much as needed to attain stability.
• Reduced water usage: coupled with RO, aqueous stream recycled and tartrate solids concentrated for cream of tartar recovery.

STABILAB determines the conductivity reduction for each individual wine at a predetermined test temperature through the relationship between temperature and conductivity of untreated wine and saturated wine.

STARS is controlled by the change in conductivity resulting from removal of ionic salts of tartrate from the wine.

STARS reduces conductivity to STABILAB's target by moving micro-layers of wine between two selectively permeable membranes.

STARS monitors the conductivity of the treated wine in real time to ensure that the target is achieved and the wine is stable.
