SUBSTANCE: plug 1 is at least partly formed of synthetic material and has cylindrical shape to provide plug arrangement in bottle neck. The plug has tubular channel to bring residual air volume present in the bottle into communication with ambient air through membrane installed transversely to the tubular channel. The membrane permits oxygen passage between bottle interior and ambient space.
