Cellogum is the carboxymethyl cellulose (CMC) produced by Enartis for use in winemaking. After recent approval by the TTB, CMC is now the technique of choice to stabilize wines by preventing tartrate precipitation, and presents numerous advantages:  

• Tartrate stabilization of wine without changing the chemical parameters (pH or TA) or sensory attributes
• Reduces energy bills and carbon emissions
• Retains effectiveness over time
• Reduces preparation time prior to bottling
• Doesn’t require investment in additional equipment
• Very low-cost treatment: from 0.015 – 0.04 USD per gallon 

Enartis started testing CMC as a wine treatment material in 2005, and since approval by the EU in 2009, several million gallons of wine have been effectively stabilized using Cellogum. Based on very extensive knowledge acquired by Enartis since the first trials in 2005, Enartis Vinquiry has developed the “CMC Panel”, a comprehensive set of tests that evaluates whether a wine is ready for CMC treatment, and the amount required to obtain stability. 

The Predictive Tartrate Stability Panel uses Mextar®2.0.en Decision Support System (DSS) to predict and manage chemical-physical equilibria in wine. It simulates various winery operations and predicts the variation of chemical-physical equilibria in wine during tartaric precipitation, malolactic fermentation, secondary fermentation of sparkling wine, acidification and deacidification. While it is a predictive tool and not intended as a replacement for actual analyses such as cold stability by conductivity, it is a valuable tool to get a sense of stability, as well as potential changes in pH and TA during these operations. These predictions can save time and expense and reduce carbon emissions.

The Predictive Tartrate Stability Panel includes analysis for Alcohol, Tartaric Acid, Potassium, pH, Titratable Acidity, Density, Volatile Acidity, and an estimate of the effect of your choice of wine treatments (acidification, de-acidification, increase/decrease in alcohol) on the tartrate stability of a test wine. Predictions for changes in TA and pH given different treatment scenarios are also available!
