Traditional methods of cold stabilization are expensive, labor intensive and time consuming. Enartis Vinquiry offers a wide range of stabilizing agents to help you quickly prepare your wine right before bottling.  These pre-bottling stabilizing agents can increase winery efficiency and reduce overall cost, while maintaining or increasing sensory quality.

Our portfolio of Tartrate Stabilizing agents is comprised of 3 main families of products:

• Citrogum and Citrogum Dry:  Gum Arabic

• Cellogum L: CMC (Carboxymethyl Cellulose)

• Enartis Stab CLK+: Mannoproteins

Citrogum is effective at the rate of 50 to 300 mL/hL and is recommended for wines that show a 3-7% change in electrical conductance. Citrogumalso improves and enhances mouthfeel and reduces bitterness and astringency. These organoleptic improvements occur with doses above 80 mL/hL. We recommend doing bench trials to confirm that the product is suitable for your wine.                                               

Cellogum L effectively stabilizes wines at dosage rates of 50 to 200 mL/hL but has no organoleptic impact. Its broad range of applications allows for cold stabilization of wines with 3-20% change in electrical conductance, making it ideal for highly unstable wines. CMC can interact with wine proteins, therefore it is important to test your wine for any possible colloidal instability.

Enartis Stab CLK+ is a blend of soluble polysaccharides (mannoproteins) extracted from yeast cell walls. Its effectiveness varies from wine to wine, thus requiring evaluation prior to use.  Enartis Stab CLK+ provides a positive impact enhancing the wine’s sensory quality and overall mouthfeel.

Note: It is of the utmost importance to remember that prior to the addition of any of these products your wine must be bottle-ready. This means the wine should have the following requirements:

• Heat stable

• Turbidity <1 NTU

• Temperature > 50⁰C

• Filterability Index <10

 

Tools to Evaluate Tartrate Stability

With more than 10 years of experience working with tartrate stabilizers in the international market, the Enartis team has designed a series of analyses and guidelines to identify the dosage rate and product most appropriate for your wine. As a result we are able to offer precise advice that will assure complete tartrate stability.

These tartrate stability assessment panels are offered through our Enartis Vinquiry Analytical Services department.
