Producing high-quality wines requires special care at every stage of the process, from the vineyard to the bottle. Among the various factors that influence the quality and stability of wine, tartar management is crucial. Tartar, composed mainly of calcium and potassium salts, can precipitate in wine, causing turbidity problems and the formation of unwanted sediments.
To address this challenge, wine producers are increasingly relying on innovative technologies such as electrodialysis.
What is electrodialysis?
Electrodialysis is a process of separating ionic substances in solution using electric fields. In practice, this technology uses selective membranes that allow only the cation or anion to pass through them, effectively separating the ionic species present in a solution.
Applications in the wine industry
In the wine context, electrodialysis has been successfully used for tartaric stabilization. The process involves two main phases:
Pretreatment: During this phase, the wine is subjected to a preliminary treatment to remove solid particles and organic substances that could hinder the functioning of the electrodialysis membranes.
Electrodialysis: The treated wine is sent through a system of electrodialysis cells, where the membranes select and separate the cations and anions responsible for the formation of tartar. This leads to the production of a stable and clear wine, free from the risks associated with tartar precipitation.
Advantages of electrodialysis for tartaric stabilization
Efficacy: Electrodialysis offers high efficiency in the removal of the salts responsible for the formation of tartar, guaranteeing the stability of the wine over time.
Better process control: The technology allows precise control of separation parameters, allowing producers to optimize operating conditions to maximize wine yield and quality.
Saves time and resources: Compared to traditional methods such as cold-stabilization, electrodialysis requires less time and resources, reducing overall production costs.
Lower environmental impact: The use of electrodialysis can contribute to more sustainable wine production, thanks to the reduction of energy consumption and the minimization of waste generated during the process.
