Abstract
An apparatus for aerating liquids contained in bottles includes a safety mechanism for detecting irregularities in the bottle and preventing undesired pressurization of a bottle having such irregularities. The apparatus includes a frame with a reference surface. A mechanism for holding the bottle in place causes the bottle to rest against the reference surface. Any irregularity in the bottle causing substantial angular displacement of the bottle activates a safety release valve in the mechanism, thus preventing over pressurization.
