Natural liquid mannoprotein preparation for tartrate stabilization White, Rosé, Red Claristar is a specialty liquid mannoprotein product from Oenobrands to aid in the natural stabilization of wines. It is the result of a patented extraction and separation technique that isolates the fraction of mannoproteins from S. cerevisiae with the highest Tartrate Stability Index (TSI). When added to wine, Claristar inhibits the nucleation and growth of potassium tartrate crystals. In addition to improved stability, the sensory balance of red, white and rosé wines are enhanced by the positive effect of the mannoproteins. Users note improved aromatics as well as smoothness on the palate. Claristar has been available in Europe since 2007. Sold as a liquid, its highly purified mannoproteins are 100% soluble in wine. It can be added directly and homogenizes easily. Thanks to Claristar’s enhanced potassium tartrate stabilization properties, wine can be treated immediately prior to bottling.

Recommended Dosage
Common dosages are 80–100 mL/hL (3–3.8 L/1000 gal) for white and rosé wines and 70–90 mL/hL (2.7–3.46 L/1000 gal) for red wines.

To ensure efficacy of a Claristar addition for stability of any particular wine, bench trials MUST be run with laboratory analysis and verification. The amount of Claristar required will be unique to each wine. Its effectiveness is dependent upon a wine's individual characteristics (e.g. protective colloid levels, pH, alcohol, etc.) in addition to a user's chosen stability criteria. The wine submitted for bench trials MUST be the final blend. Claristar should be the final addition to any wine prior to filtration and bottling. Please contact Scott Laboratories, Inc. for more information regarding the bench trial requirement.

Note: Claristar is not appropriate for calcium tartrate stabilization problems.

Usage
Claristar can be considered for use in white, rosé, and red wines that meet the below criteria:
• Are the final blend
• Have never been pH adjusted with calcium carbonate
• Are confirmed protein stable
• Are under 16% alcohol by volume
Claristar should never be added to a wine prior to cake/DE/Earth/ Velo filtration, or cellulose pads. It can be added prior to crossflow and sterile cartridge filtration.
Storage
