Memstar Reverse Osmosis

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.

For example…

  • Reduce excess alcohol.
  • Remove volatile acidity.
  • Remove Brettanomyces taint compounds (4-EP and 4-EG).
  • Remove smoke taint compounds.
  • Remove water from grape musts.
  • Increase wine concentration.
