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.
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.
