How hard is it get all the o2 out of the headspace if I only rack 2 gallons into a corny? Plan to force carb. Can I just purge and burp a couple times and call it good or is there a trick to knowing all the o2 is gone?
Fill with water and push it out with CO2. What you are describing will only give you increasing levels of dilution and with that much head space it will take a lot of purging.
