Summary:The invention relates to a plant for de-alcoholizing a product containing ethanol, for example beer or wine, which plant comprises a preheating stage (5) for heating up the product and an evaporator arrangement (1) drawing product vapours from the product heated up in the preheating stage (5) and discharging the de-alcoholized product. A mechanical vapour compressor (33) compresses the product vapours from the evaporator arrangement (1) and supplies the compressed product vapours to the evaporator arrangement (1) for the heating thereof. In order to heat the preheating stage (5), product vapours from the evaporator arrangement (1) are supplied to the preheating stage (5) through a bypass route (37, 39) to the mechanical vapour compressor (33), at least a part of the product vapours being condensed by means of the preheating stage (5). The bypass route preferably includes a thermal vapour compressor (39).
