Description
-
Provides rapid and permanent tartrate stabilization against potassium bitartrate (KHT) crystal formation, eliminating the need for chilling or extended settling times
-
Preserves wine quality with a formulation that has no sensory impact on aroma, color, flavor, or mouthfeel, and is compatible with standard winemaking practices like filtration
-
Offers a sustainable and convenient solution that is vegan, allergen-free, requires no refrigeration, and is compliant with international regulations (OIV approved)
-
Ensures long-lasting stability due to the hydrolysis-resistant nature of potassium polyaspartate (KPA), maintaining its effectiveness throughout wine aging and under varying temperatures
Enartis Zenith Uno is a cutting-edge solution for tartaric stabilization in white, rosé, and sparkling wines. Formulated with potassium polyaspartate (KPA), this next-generation additive provides fast, reliable, and permanent stabilization against potassium bitartrate (KHT) crystal formation—without the need for refrigeration or extended settling times.
How It Works:
Zenith Uno’s active ingredient, potassium polyaspartate, is a polypeptide derived from aspartic acid. This polymer inhibits crystal nucleation and growth by binding to nascent KHT microcrystals, effectively preventing them from aggregating and forming visible tartrate deposits. Unlike traditional methods such as cold stabilization or metatartaric acid, KPA is resistant to hydrolysis, meaning its stabilizing effect is long-lasting and unaffected by wine aging or elevated storage temperatures.
Scientific Highlights:
-
KPA molecules act as a crystal growth inhibitor by interfering with the surface structure of KHT nuclei.
-
Demonstrated stability in wine over time, even under variable temperature conditions.
-
No sensory impact: Multiple trials confirm that KPA has no effect on aroma, color, flavor, or mouthfeel.
-
Compatible with protein and color stability tools such as bentonite and PVPP.
-
Does not interfere with crossflow filtration or other standard winemaking operations.
Key Benefits:
-
Permanent tartrate stabilization
-
No need for chilling, aging, or post-treatment filtration
-
Preserves wine’s freshness and sensory profile
-
Vegan and allergen-free
-
Approved by OIV (OENO 543-2016) and compliant with global regulations
With Enartis Zenith Uno, winemakers can achieve brilliant clarity, stability, and peace of mind—all in a single, easy step. Efficiency has never tasted so good.
Do Protein Stabilization First
Use KWK Klear bentonite or, for very high-quality wines, Claril ZW to achieve protein stability before using Zenith Uno for tartrate stability.
