Wine acidity a big challenge for winemakers

Wine acidity adjustment

Wine acidity adjustment

The production of wine from fermented grapes is based on centuries-old traditional practices. Wine acidity adjustment is one of the procedures that enrich traditional production with modern technologies and practices.

The pH value of wine has a significant impact on its organoleptic properties (freshness, aroma, flavor, etc.). An unstable pH, especially its increasing values in recent years, causes oxidation of wine, and premature aging, i.e., deterioration in wine quality, which can cause wine producers to lose markets.

Optimize wine acidity using bipolar electrodialysis

Optimize wine acidity using bipolar electrodialysis

Bipolar electrodialysis (EDBM) is an innovative technology for winemakers to naturally and precisely adjust the pH of wine and must. This electro-membrane technology does not require any additives and is therefore compliant with regulations for fully organic products.

Adjusting the pH value of wine using EDBM involves only changing the concentration of cations or anions and replacing them with H+ or OH- respectively, thus optimizing the natural acidity.

Bipolar electrodialysis is a very efficient technology for wineries with low energy and chemicals (for cleaning) consumption.

Bipolar electrodialysis as a solution for adjusting pH of wine

Why use MEGA electrodialysis for wine purification

Why use MEGA bipolar electrodialysis (EDBM) for wine acidification and deacidification

MEGA presents a bipolar electrodialysis for adjusting wine pH with no need for additional chemicals, the wine remains natural. Therefore, this technology is suitable for organic wine production

With MEGA membrane technology, you can adjust the pH both up and down to achieve a harmonic balance between sweet and acid taste. The usual pH change is up to 1.

Our innovative bipolar electrodialysis is developed for both small and large wineries. We supply technology tailored to the customer's needs, therefore the EDBM unit can be used in both stationary and mobile versions.

Using MEGA bipolar electrodialysis you get the final product of higher quality with lower OPEX.

Benefits of MEGA bipolar electrodialysis

Benefits of MEGA bipolar electrodialysis

  • Minimal wine loss compared to other conventional methods.
  • Easy pH adjustment (pH change from 0.1 to 1.0).
  • Additive free technology - fully organic wines.
  • No legislation limits.
  • Low operating costs - no chemical additives required (no tartaric acid, no malic, lactic, etc.).
  • Continuous, fully automatic process.
  • Cost-effective, reliable.

Wine pH adjustment - how does it work?

Wine pH adjustment - how does it work?

The goal of wine pH adjustment is to find a harmonic balance between sweet and acid taste. MEGA electrodialysis with bipolar membrane process (EDBM) is based on the unique property of bipolar membrane (BM) in combination with monopolar cation/anion membranes (CM / AM).

EDBM adjusts a solution’s pH without adding bases or acids. BM effectively splits water (H2O) into H+ and OH under the influence of the applied electric field. CM and AM transfer cations or anions selectively generate acid and caustic streams. Therefore, acids or basis in wine are replaced with OH and H+ respectively, and you can easily set up wine pH both up and down (deacidification/acidification).

Wine acidification
Wine not acidic enough grown mainly in hot areas (south of USA, Australia, South America) - the BM-CM module is designed for acidifying wine.

Wine deacidification
Wines too acid grown mainly in cold areas (north of USA, Germany, Alsace, north of Europe) - the BM-AM-AM module is designed for deacidification.

MEGA EDBM vs competitive technology

MEGA EDBM vs competitive technology

Simple implementation to the already existing manufacturing lines.

The MEGA EDBM technology uses a lower amount of chemicals for the process (without regeneration of ion exchange columns) and CIP. And at the same time, it shows a significant reduction of waste water from production.

This dramatically reduces the footprint of wine production. In general, bipolar electrodialysis is an automatic system that is easy to operate and maintain and significantly reduces the environmental impact.

Compare to other technologies EDBM doesn’t touch the basic structure of material but removes dissolved solids by the natural attraction of charged ionized particles towards the electrodes. There is no need for additives.
