Abstract: In known beverage dealcoholizing plants, one disadvantage is that volatile content materials always escape, and the end product consequently lacks aroma materials and/or preserving materials that were previously present. This disadvantage is eliminated in that the volatile content materials, previously lost into the surroundings via the vacuum pump, are fed back again into the beverage. A duct at the exhaust air pipe, connected to the vacuum pump and leading to a gas washer, circulates the volatile content materials back into the beverage.

Abstract: A process for producing low alcoholic wine includes the following steps: evaporating alcohol-containing wine in a vacuum evaporator so that a first mixture comprising water, alcohol and flavoring substance is separated from a second mixture having a low-alcoholic content, separating water from said first mixture in a multistage flavor substance apparatus and drawing off a third mixture comprising alcohol and flavoring substance, distilling alcohol from the third mixture, adding the water from the multistage flavor substance apparatus to a mixing vessel in an amount, which together with the low-alcohol second mixture and the flavoring substances produces a quantity of low-alcoholic wine having an alcoholic content below legally determined values for low-alcoholic wine, the process allowing only outputs of low-alcoholic wine, distilled alcohol and flavoring substances and inputs of essentially only the alcohol-containing wine.
