ABSTRACT:
A continuous fermentation process is performed in an apparatus system having at least two circulation fermenters arranged in a cascade. Fresh must is introduced into a first fermenter for fermentation with a flocculating yeast, growth of the yeast in the first fermenter being promoted by introduction of oxygen. The fermenting must and yeast are transferred from the first fermenter to a second fermenter and then to any subsequent fermenters of the cascade serially. In the second and any subsequent fermenters, the growth of yeast is inhibited. After passing through the last fermenter of the cascade, be it the second or a subsequent fermenter, yeast is separated from fermented must, and the separated yeast is removed from the system and is not recycled.
