Volatile Acidity Reduction

Volatile Acidity Reduction

Managing volatile acidity (in the form of acetic acid & ethyl acetate) in wine production is crucial as excessive levels can lead to unpleasant characters in a finished product. In the same manner, volatile imbalances can radically alter a wine’s aroma, balance and ultimately, market appeal. Our unique VA reduction service can accurately reduce volatile acids efficiently and safely – providing cost-effective solutions while maintaining quality.

How does it work?

The VA reduction process involves circulating the wine through a reverse osmosis plant to isolate a permeate to be treated. This permeate – comprised of water, alcohol, and the volatile acids to be corrected – is treated in an anion exchange column that absorbs the acetic acid. Finally, this treated solution is recombined with the concentrate and returned to tank.

Benefits

  • Significant impact upon stuck fermentations
  • 30% minimum volatile acid reduction on a single pass
  • Efficient 1,800 – 4,000 litres per hour
  • Capable with small or large volume processing
  • Selective membranes capture only volatile acid, preserving quality
  • Lower treatment pressure places less stress on the wine
