OK this one crops up on US sites quite often, and that is you can't use plastic for long term storage of beer because air will diffuse through the walls and your beer will suffer from oxidisation. A recent posting on HBD suggested that plastic shouldn't even be used for long term lagering (I'm pressuming they mean maybe 6-8 weeks).
In Australia most of us use plastic for our fermenters and even CCing/lagering, so what is the collective wisdom on this. Is it true or is it a myth. Does anyone have any hard data on the amount of air that diffuses across a plastic fermenter wall, and how much oxygen actually makes its way into the beer? Just an assumption, but I would think that your beer gets exposed to more oxygen during racking.
Thoughts?
