About Memstar

The Memstar process is a diversely capable technology, capable of providing a tailored service that can solve a diverse range of issues with wine production – alcohol correction, volatile acidity reduction, Brettanomyces/smoke taint removal, and flavour concentration.

How does it work?

Memstar involves a unique reverse osmosis process that separates the wine to be treated into a concentrate and permeate. The permeate can then be treated through a choice of specially designed filters to correct or remove undesirable components, and finally be recombined with the concentrate. The closed loop system design means that the wine can be separated, treated, and recombined as many times as required.


  • Selective removal with minimal impact on wine quality
  • Ingenious closed loop design satisfies regulations and permits continued treatment
  • Cost-effective solutions with a range of machine sizes, mobilities and technician services to suit every need and budget
  • Efficient and energy conscious – capable of processing up to 4,000 litres per hour to minimize energy demands
  • Industry-leading quality and assistance
