A beverage bottling plant and method for filling bottles with a liquid beverage having a treatment device for beverage container caps. The treatment device for treating beverage container caps includes a first tower and a second tower provided with parallel axes and driven at the same peripheral speed. Transfer chutes are provided that emerge with their ends onto carrier rings of different towers, which chutes transfer caps from each tier of the first tower to a tier of the second tower, and from there, optionally via at least one additional tower and transfer chutes, to the next-lower tier of first tower.
