Method
Osmotic distillation
A membrane process that pulls ethanol across a hydrophobic barrier into a stripping solution, usually at or near room temperature.
Osmotic distillation — also called evaporative pertraction — sits with reverse osmosis in the membrane family, but it is not the same tool. A hydrophobic membrane separates the wine or beer from a stripping liquid. Ethanol vapor crosses. Water mostly does not. The feed can stay close to cellar temperature.
Technical reviews treat it as a recognized dealcoholization method, with published wine work down to around 0.2% ABV. It is not “reverse distillation.” If a producer will not name a membrane or a stripping solution, do not upgrade a marketing sentence into this page.
We will file a review here when a cited source actually uses the term.
