About VAF

VAF is our comprehensive volatile acid treatment service. Safely removing excesses of acetic acids and other undesirable ethyl compounds is the most efficient way to improve the quality and desirability of a wine or to correct imbalances in poorer quality yields. Our unique reverse osmosis technology ensures efficient processing while ensuring little impact on the wine or loss of volume.

How does it work?

The wine to be treated is first separated into a concentrate and permeate containing the volatile acids. This permeate is then processed through an anion exchange column where the acids are absorbed by the charged resin cartridges. The acid-free permeate can then be recombined with the concentrate. As a closed loop system, the process can be easily repeated until the desired acidity is achieved.
