I was reading a post in another thread that referenced the palmer book that said every time the opportunity to introduce oxygen comes there is jeopardy. So would it be reasonable when racking to rack to a closed container that has first been filled with CO2? It would be rather easy to do and would avoid the possibility of Oxygen introduction. What do you all think? Also you could displace the oxygen in the bottle with CO2 when bottling.
Doing what you say is a good thing to do. If you can, purging any vessel with co2 that you put beer into will help with oxidation. Racking into a closed container will work if it is not completely sealed; whatever gas is inside the container has to have somewhere to go.
There’s a video on-line by a guy who does all his fermentations in corny kegs and transfers from one to another with co2 pressure. Not a bad idea if you want to put in the effort to do it.
