Using collapsable bags to displace o2 during racking/packaging

Hey Blisch – tell you what. I’ll fill that bag with Co2 and let you inhale it. Then you tell me how much Co2 you think is in it. It definitely displaces the fermenter with Co2 when used as I suggedsted.

Yeah, eventually that collapsable bag will exchange o2. Though these are extremely sturdy bags. They aren’t exchanging o2 over the 1-2 hours I’m using them.

I’m guessing you either didn’t entirely read the purpose I proposed or you are fixated my suggesting they could be a way to capture Co2 for bottle conditioners or secodnary users without acess to Co2. I still think they could be used for this as well. I think they will exchange very little gas in that period.

How about instead of inhaling and guessing we use the proper instrument to determine if that is the case or not? Sturdy… is that a good rating of the O2 permeability of plastic? I read exactly what you posted and I am telling you that oxygen will get through your sturdy bag and into the headspace of your jar. Believe it or not.

If I fill a collapsable bag (please view the particular one I posted, I’m not talking about a WalMart shopping bag) with Co2 … it’s going to be filled with Co2 for all intents and purposes. This is a laughable argument. And I’m the one who should be laughed at most for arguing about it when this really just feels like an attempt to troll for no other reason but to troll.
