I have a co2 jetter in front of the capper to create a foam to evacuate the air in the headspace. How ever sometimes during a filling day there is a good foam already from the filler. When the bottle with foam comes under co2 jetter, the jet stream do not go through the foam so it just compact the foam so there will be a space between the foam and the cap. Can I assume that this space mostly consists of co2 or air? (I think that the foam created during/after snifting comes from to low pressure in the filler bowl combinated with bad gaskets in the filling valve so the filling valve do not close properly. The problem is more common when the pressure in the BBT goes under 0.7 bar. The cent. pump makes about 0.5 bar so the pressure in the bowl goes down to 1.2 bar.)
