(WB) - Zenith Uno and Zenith Color can be added to a wine to achieve cold stability without that wine having to be seeded and chilled or subjected to electrodialysis. The active compound in both products is a polymer of aspartic acid.

The United States Food and Drug Administration issued a letter of understanding on September 11 that will allow two products–Zenith Uno and Zenith Color–to be called GRAS (Generally Recognized As Safe) compounds.

Developed by Enartis, Zenith Uno and Zenith Color are amendments that can be added to a wine to achieve cold stability without that wine having to be seeded and chilled or subjected to electrodialysis. The active compound in both products is a polymer of aspartic acid. 

Zenith Uno and Zenith Color are both approved for use in the European Union, but to-date have not been approved for use by TTB. The letter of understanding is an important step towards that approval.
