The VA Filtration and Memstar group have 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 its latest development.
In February, Wine Australia issued a warning to wine exporters to China as a result of a number of Australian wine shipments being rejected by Chinese authorities. The reason was ‘excessive’ manganese content of more than 2mg per litre even though manganese is not a wine additive and consequently not a routine analysis. While there are no known health or quality issues associated with wines over that limit, this somewhat arbitrary limit has created a serious problem for wine exporters to China.
With this in mind, the R&D team at VA Filtration & Memstar have been working to offer wineries a means of safely removing manganese from their wines. Trials using a newly developed process combining nano-filtration and resin treatment have shown reductions in manganese from 2.0 mg/l to below 0.6 mg/l. The process is gentle on client’s wine; there appear to be no negative side effects; and it is cost effective.
VA Filtration and Memstar’s team take great care from start to finish and can treat anything from one barrel to one million litres or more. Wine exporters with potential problems should call to discuss their options: 08 8562 1139 or 1300 MEMSTAR
