Abstract
Stopper intended for bottling still wines, characterized in that it includes cork strips laterally joined by a polyurethane binder so as to form a plurality of cork strips, the cork strips being disposed such that the thickness thereof is perpendicular to the axis of the stopper, at least one lateral cork strip joined by a polyurethane binder to each face of the plurality of cork strips revealing all cork strips, the lenticels possibly present in the cork strips extending parallel to the thickness of the strips while those in the lateral cork strips extend perpendicular to the thickness of the strips, such that all lenticels of the stopper are disposed perpendicular to the axis of the stopper in order to limit the variation in oxygen permeability from one stopper to the other.
