ABSTRACT:
The present invention describes a cartridge of hollow fibers intended principally for the refermentation in the bottle of sugar-containing wine according to the traditional so-called "champagne" method. The cartridge has a perforated tubular body in which are arranged microporous hollow fibers preferably hydrophilic and a few hydrophobic and which are folded in a U shape and which are filled with yeasts. The cartridge is of a size to be inserted in the neck of a bottle and allows refermentation to occur by ensuring the maintenance of an optimum exchange surface between the wine and the yeasts.
