Abstract
A gassing apparatus for breaking bubbles at the surface of a newly filled bubbling product (beer) and thereafter removing air from the head space above the surface of the product. The gassing apparatus includes a new bubble breaker which provides for the breaking of the bubbles at lower than customary gas pressure followed by a gassing rail which is of sufficient length and gassing apertures to permit full air removal notwithstanding variations in head space. Preferably the bubble breakers are used in pairs with the gas in the second bubble breaker being at a pressure less than that in the first.
