Alcohol Reduction, Correction & Adjustments in Wine


VAF Memstar provides a suite of services for reducing alcohol content in wine, including alcohol reduction, adjustment, and correction services.

Why is reducing alcohol content in wine important? Imbalanced alcohol levels in wine can severely affect the quality of the product, and possibly prevent market accessibility for winemakers – especially following recent alcohol tax and duty changes.

Our alcohol reduction services can provide the desired alcohol content in wine, without sacrificing quality. Our service includes regular sensory trials for winemakers to assure quality and accuracy before final reduction processes occur.

How do we adjust alcohol in wine?

Employing our patented reverse osmosis technology, the wine is separated into a concentrate and the alcohol-rich permeate. The permeate is then heated and passed through a specialized membrane that filters out alcohol while leaving other important components intact. Each pass typically removes approximately 1-2% of alcohol. The single tank recirculation method means that the process is simple to operate until the desired alcohol level is reached.

Benefits of Alcohol Adjustment

  • No addition of water to the wine, preserving quality
  • No heating of the wine, preserving flavour
  • Minimal losses of volume
  • Affords immediate onsite assessment
  • Efficient and cost-effective
  • Treat 1,500 – 21,000 litres per hour
