A pressure control device for controlling a pressure in a beverage container comprises a gas filled pressure control chamber enclosed by a wall of the pressure control device. The wall has an inner surface facing the chamber and an outer surface facing away from the chamber, the inner surface and outer surface defining a thickness of the wall. A scavenger material is provided in the pressure control device for capturing gas that enters, during use, into the pressure control chamber. The scavenger material is distributed over the wall thickness with a predetermined concentration from the inner surface towards the outer surface of the wall such that a rate of gas capture by the scavenger material changes over time.
