Adjust the Level of Alcohol in Your Wine with Reverse Osmosis

In the Reverse Osmosis (RO) process, wine is pumped at a high pressure past a semi-permeable membrane. The wine is separated into two streams, the permeate being small molecules (water, ethanol), and the retentate being the higher molecular weight components of the wine.

This water/alcohol stream is then further processed through a distillation column, where it is separated into an alcohol distillate and pure water. The desired stream is then added back into the wine. If reducing alcohol, the water component is replaced in the wine. If concentrating, the permeate is not replaced, and may be processed for another use.

Our customers use our service to :

  1. Reduce Alcohol
  2. Concentrate Wines
  3. Concentrate Juices
  4. Increase Alcohol

Our Units:

RO Unit 1 & 2 – Reverse Osmosis System – 16 module unit

RO Unit 3 & 4 – Reverse Osmosis System – 6 module unit

Reverse Osmosis can also be used to remove rain water from juice, to remove Brettanomyces, and to remove smoke taint.

The use of RO allows you to adjust your alcohol to maximize flavour, or to remove undesirable components and restore flavour to your wine.

RO units require low turbidity wine for optimum flows. Reverse osmosis is not a filtration, so any acetobactor or bacteria that may have caused wine issues will not be removed. We recommend filtering first with our Crossflow MF service.
