Carboxymethyl Cellulose gum solution (CMC, or E466).
CELSTAB® is intended for wine stabilization in relation to tartrate salt precipitations.
Its action results in an inhibition of microcrystal nucleation and growth phases (via disorganization of the surface of the salts that are required for crystal formation).
• Recomended dosage: 100 mL/hL. For wine production in the EU: maximum legal dose for white, rosé and sparkling wine: 200 mL/hL (200 mg/L / 200 ppm).
• Recommendation for wines with high potassium bitartrate instability:
• Prior laboratory testing to check dosage.
• Stability testing to validate the efficiency of the treatment
