The Unique new apprpach to wine alcohol adjustment
Go with the flow – the benefits of Memstar AA
Patented 2 stage membrane process preserves precious flavours, colour and tannin
With the Memstar AA reverse osmosis and perstractive membrane process, wine alcohol is selectively reduced while flavours, colours and tannin are preserved.
The process is a “ closed loop “ with two membrane barriers between the wine being treated and the strip water which removes the alcohol.
The actual stripping step is performed on reserve osmosis permeate which contains very little of the precious wine characters that would otherwise be lost.
Wine quality maintained – no additions
The process is carried out in alcohol oxygen free environment and does not involve the addition of any extraneous material which dilutes wine flavours or otherwise degrades quality.
No water addition – no legal issues
The process does not involve the addition of water to wine – a practice which is not permitted in most wine producing countries. It also avoids the legally dubious addition of water from other grape sources.
No distillation – no regulatory issues
The process does not involve distillation ( high or low temperature ) with its substantial infrastructure and energy costs; also avoiding the taxation. OH&S and other regulatory issues associated with the production and handling of high strength alcoholic spirit.
Minimal volume loss
Virtually only alcohol is removed so the volume losses are minimal
Wine processed entirely on-site
The whole process is performed on site by our skilled personnel using Memstar’s unique mobile equipment. No need for the wine nor the permeate to be shipped away for further processing.
Getting the alcohol right
To determine the optimum final alcohol level, the winemaker can perfom “sweet spot” trails at the commencement can stop. Then, monitoring progress, the winemaker can stop the process at the preferd alchol level.
