VA Filtration has a long and proud reputation for innovation, helping winemakers deal with what were previously intractable problems such as excessive VA, alcohol, Brett and smoke taint. Dealing with excess manganese is another of these developments.
Treatments using a newly developed process combining nanofiltration and resin treatment have shown reductions in manganese from as high as 4.7 mg/l to below 0.6 mg/l.
The process is gentle on client’s wine; with no negative side effects; and it is cost effective. The VA Filtration team take great care from start to finish and can treat volumes from one barrel to one million litres or more. Wine exporters with potential high-manganese problems should contact us to discuss their options.
