A full aperture beverage end has a center panel, a countersink surrounding the center panel, a main score arranged in proximity to the countersink to define a removable aperture panel and a vent score. The beverage end is adapted for use with products that are pressurized to over 30 psi (200 kPa) when opened, and during opening the vent score is adapted to sever first, controlling the pressure differential between the external surface and internal surface of the center panel, thereby allowing the main score to tear in a controlled and reliable manner.
