Tartrate stability | Enartis

Enocristal Ca

Enocristal Ca is a micronized calcium tartrate selected for wine calcium stabilization. It triggers the formation of calcium tartrate crystals and promotes calcium stabilization process.

AMT Plus Quality

Pure metatartaric acid produced by Enartis from food grade L-tartaric acid. When added to wine, AMT Plus Quality prevents the growth of potassium bitartrate and calcium tartrate crystals, making the wine stable against tartrate precipitation. Its high esterification rate (from 38 to 41) allows a long-lasting protecting effect. This means that cold stabilization processes can be reduced when refrigeration capacity is not available or not cost effective.

EnartisStab Cellogum LV20

Aqueous solution containing 20% low viscosity sodium carboxymethyl cellulose (CMC). To be used in a finished wine to inhibit the formation and growth of potassium bitartrate crystals which could precipitate after bottling. EnartisStab Cellogum LV20 has a long-lasting effect and can completely eliminate the use of physical stabilization treatments such as cold stabilization and electrodialysis. This significantly reduces energy costs and processing times. Because of its low viscosity, EnartisStab Cellogum LV20 has a low impact on wine filterability and this makes it the ideal solution to be used when CMC is added before microfiltration.

EnartisStab CLK+

EnartisStab CLK+ has a new formulation where mannoproteins’ efficiency is reinforced by KPA tartrate stabilization. Therefore, the new EnartisStab CLK+ formula is more performant in preventing potassium bitartrate precipitation in bottle and can be used as an alternative to physical stabilization treatments. At the same time, it maintains the usual effect of improving wine mouthfeel and softness.

Zenith Uno

Solution of A-5D K/SD potassium polyaspartate (KPA) and sulfur dioxide. Zenith Uno is an effective, rapid and easy-to-use tool for potassium bitartrate stabilization in wine. It is able to assure a long-lasting stability also in wine with a high level of tartaric instability. For this reason, Zenith Uno can easily replace cold stabilization and other physical treatments. Moreover, it does not impact wine sensory quality and filterability. The liquid form allows for simple and fast use.

Zenith Color

Solution of A-5D K/SD potassium polyaspartate (KPA), Gum Arabic Verek and sulfur dioxide. Zenith Color is an effective, rapid and easy-to-use tool for potassium bitartrate and color stabilization of red and rosé wines. It assures no changes in quality or characteristics of wine with full color and tartaric stabilization in a single addition. Zenith Color does not significantly modify wine filterability and can be added before microfiltration.
