Montpellier, France. Claristar: More than a tartrate stabilization, an enhancement of the white and roses wines.


Oenobrands developed Claristar, the mannoprotein fraction with proven instant action on the potassium tartrate stabilization of white and rosé wines. Claristar has been on the market since 2007 and is recognized by 98% of users as easy-to-use, fast, precise and non-traumatic for wines (survey on 1200 batches of wine treated with Claristar).


Highly soluble, Claristar interacts with microcrystals to stop their growth and keep them at a size invisible to the eye. Claristar is an unmatched natural alternative to exogenous and harmful stabilization techniques, thanks to the positive action of the mannoproteins on colloidal balance.


This method presents the additional combined benefit of preserving the wine’s aroma, colour and natural acidity. Customers testify to this, since 92% of tasters observe comparing to wines stabilised using cold treatment, an increased aroma expression, a sensation of volume and roundness on the palate and an improved aromatic freshness during wine storage.


The liquid formulation facilitates the instant stabilizing effect, allowing immediate final filtration. The use of Claristar results in an average 15-day reduction in the tartrate stabilization process.

Many winemakers worldwide already benefit from the use of Claristar and testify to its added value. This innovative liquid ingredient is easy to use by following the simple application recommendations.


This is another ADVANCED WINEMAKING SOLUTION brought to you by OENOBRANDS.

Press Release Claristar - May 2012 (EN)

Published in Press Releases

Oenobrands is extending Claristar, its mannoprotein application for still wine tartrate stabilization, to all colors: initially for white and rosé wines, Claristar is now available for red wine stabilization.

Marketed since 2007, Claristar prevents the formation of potassium bitartrate crystal nuclei. This application is entirely soluble and has already proved its efficiency in tartrate stabilization on white and rosé wines, thanks to its specific mannoprotein formula that has the highest tartaric stability index (TSI) among the large number of mannoproteins naturally present in yeast and wines.

Over the last three years, Oenobrands has carried out a number of application tests on multiple batches of red wines in collaboration with Enolab, the analysis laboratory run by Dario Montagnani in Tuscany (Italy). These high volume operations have demonstrated that the mannoprotein contained in Claristar stabilizes red wines just as sustainably as white and rosé wines, with no risk of the haze associated with polyphenols.

Thanks to these years devoted to development and validation, an analytical reference method has been set up to determine the level of tartaric instability in red wines as well as white and rosé wines, and to determine the dosage of mannoproteins required to stabilize the wine. The protocol then confirms the stability obtained with the determined dosage by analysis.

Tartrate stabilization resulting from this method developed using Claristar is safe, simple and immediate, and also offers undeniable qualitative and organoleptic benefits. This liquid product that is immediately miscible in wine improves the latter’s organoleptic characteristics, including aroma expression and its ability to retain color and natural acidity.

Tasters have also noted that the sensation of roundness and volume on the palate is increased, and fresh aromas are maintained during storage, especially in relation to other techniques such as cold treatment.
