Claristar is a specialty mannoprotein product from Oenobrands for 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 stability the sensory balance of red, white and rose wines are enhanced by the positive effect of the mannoproteins. Users note improved and fresher 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 instant stabilization properties, wine can be treated immediately prior to bottling.
Common dosages are between 80ml/hL and 100ml/hL for white and rose wines, 70ml/hL and 90ml/hL 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. Please contact us for more information.
