A cork (15) intended for bottling still wines, characterized in that it comprises cork strips (11) joined laterally by a polyurethane binder so as to form a plurality of cork strips, the cork strips (11) being arranged so that their thickness is perpendicular to the axis of the cork, at least one lateral cork strip (13) joined by a polyurethane binder to each face of the plurality of cork strips, leaving the entirety of the cork strips (11) exposed, the lenticels possibly present in the cork strips (11) extending parallel to the thickness of the strips while those in the lateral cork strips (13) extend perpendicular to the thickness of the strips, so that all the lenticels of the cork are arranged perpendicular to the axis of the cork in order to limit the variation of oxygen permeability from one cork to another.
