Memstar (MEMbrane Seperation Treatment And Removal) is a family of membrane-based processes for adjusting wine composition and enhancing quality. These technologies are offered in New Zealand as on-site services exclusively by Vintech Pacific.
In general, Memstar Reverse Osmosis is used to “surgically” remove a low-molecular-weight constituent of the wine with minimal changes in the rest of the wine’s composition.
- Reduce excess alcohol.
- Remove volatile acidity.
- Remove Brettanomyces taint compounds (4-EP and 4-EG).
- Remove smoke taint compounds.
