Abstract: In accordance with the process of the invention a fermentation mixture is fed to an upper part of a fermentation zone by way of uniform spreading of the mixture throughout the fermentation zone, this being followed by transferring the wine being champagnized to a biogeneration zone by way of uniform spreading of the wine throughout the biogeneration zone with concurrent separation of a liquid sediment in the lower part of this zone. In an apparatus for carrying said process into effect in a reservoir for the fermentation mixture and in a reservoir for biogeneration the lower portions thereof are made conical, said reservoirs accommodating devices for uniform spreading of the liquid throughout the volume thereof. In the reservoir for biogeneration said device is arranged above the conical portion thereof, whereby a zone for sediment accumulation is provided.
