Abstract
A device particularly suitable for refermentation of sugared wine in a bottle according to the champagne method consists of a cartridge comprising a tubular body formed with grooves and perforations which provide fluid communication between the exterior of the cartridge and its inner bore. In one embodiment a portion of the perforations are covered by a hydrophilic membrane filter and another portion by a hydrophobic membrane filter, both of which are sealingly welded or glued to the exterior of the body. In a preferred embodiment, one of the ends of the tube is open and sealingly covered by the hydrophobic membrane filter while the hydrophilic membrane filter covers the perforations. The cartridge can be filled with yeasts and inserted into the bottle neck to allow fermentation to occur without the need for manipulation and disgorgement of congealed wine through the bottle neck.
