Mannoprotein for potassium tartrate stabilization

CLARISTAR® assists with potassium tartrate stability (inhibits potassium drop-out) and colloidal stability in compatible wines.

• Enhances the sensory balance of wine and users note improved aromatics as well as smoothness on the palate
• CLARISTAR is not appropriate for calcium tartrate stabilization
• Bench trials must be run to determine a wine’s compatibility with CLARISTAR (contact us for more information)
• Compatible wines can be treated immediately prior to bottling without additional racking because CLARISTAR is 100% soluble in wine
• Mannoproteins have some stabilizing effects on wine, though the addition of this product is not a replacement for good winemaking practice or thorough analysis
• Not for use in sparkling or sparkling base wine
• Highly purified liquid solution of mannoproteins with the highest Tartrate Stability Index (TSI)

Stage of Winemaking: Pre-bottling
Requires Racking: No
Impact: Inhibits potassium tartrate precipitation
Format: Liquid
Frequently used in: reds, whites and rosés that meet the following criteria:

• Wine is the final blend
• Has never been pH adjusted with calcium carbonate
• Are confirmed protein stable
• Are under 16% ABV

---

Recommended Dosage: Bench trials recommended

• Wine 600–1250 ppm (60–125 mL/hL) (2.27–4.7 L/1000 gal)

Usage: CLARISTAR should be the last commercial product added to the wine before bottling. Add after final blending, protein stabilization, fining, and pre-filtration (DE, lenticular, or sheet). Add to whites/roses 24-48 hours prior to bottling and reds 4-5 days prior to bottling. CLARISTAR can pass through final membrane filters (0.45 μm) found on most bottling lines, though filtration is not required when using CLARISTAR.

Note: CLARISTAR can pass through a 0.2 μm nominal crossflow filter.

Storage: Dated expiration. Store in a cool, dry environment between 10 and 15°C (50-59°F). Once opened, store between 5 and 10°C (41-50°F) use within 2 weeks. Can be frozen once.

Note: CLARISTAR is not appropriate for calcium tartrate stabilization.
