Hi I am trying to get my head around the gas purging when filling a bottle. I totally understand you don't want oxygen in or as little as you can. If you use a carbonation cap, that is different and will be 100%. I watched a guy in a video - Gas purged the bottle, then filled it up to overflow, pulled out the filler and then left a gap of 2cm, then capped. Surely as you will the bottle everything including oxygen or co2 you put in is being pushed out, and then when you pull the gun out it leaves a gap filled with oxygen. Seems pointless? What have a missed? If I was going to put in the fridge to drink would I have to worry about gas purging anyway?
I can understand if you were going to store the bottles for a while, but I cannot see how the top does not get filled with oxygen unless you were in an air tight CO2 chamber?
