Reverse Osmosis (RO) allows wine to be pumped at high pressures past a semi-permeable membrane to separate the water and ethanol from the wine. The filtrate which passes through the filter membrane contains virtually no anthocyanins, phenolics, tartaric, malic, or citric acids. This means that the characteristics that make up a wine, never actually go through the filter!
Our setup for VA removal has been revamped with a state-of-the-art design. We operate a Della Toffola Reverse Osmosis Filter that has 8 RO membranes capable of an output on average of 250 gallons an hour of permeate. The permeate goes through custom-built sanitary tanks with resin that traps Acetic Acid and the treated permeate is mixed back with the original wine.
If you are having challenges with VA or Bret… we can help. The use of reverse osmosis allows you to remove undesirable components and restore flavor to your wine. We always recommend that you sterile filter before using RO and we are
happy to provide support with our crossflow filter at the same time.
