Abstract
In a process for the reduction of the alcohol content of alcoholic beverages, in which aromatic substances are extracted with liquid or supercritical CO.sub.2, alcohol is separated by distillation and the extracted aromatic substances are at least partially recycled to the beverage with reduced alcohol content, the feedstock, especially wine or beer, is first subjected to a distillation under subatmospheric pressure. The distillate is subjected to an extraction with liquid or supercritical CO.sub.2, after which the extract is partially expanded to separate the aroma, and then under the residual pressure is recycled to the bottom product of the distillation in a collecting tank for the end product.
