Abstract A process is described for preparing in particular alcohol- free wine in which by extraction with supercritical CO2 firstly a specific aroma fraction with limited ethanol content is separated from the starting wine. The residual wine is then subjected to a vacuum distillation in which apart from the complete separation of the ethanol from the residual wine a fraction of more difficultly extractable aromatic sub- stances not affected by the extraction is recovered which in the end together with the extract is added to the dealcohol- ized residual wine again to obtain an alcohol-free wine, The method permits an almost complete removal of the alcohol content without detrimentally affecting the basic wine and with retention of all the aromatic and flavouring substances characteristic of the wine.
