I am conditioning a stout in a Pepsi corny keg, but I am also cold extracting coffee beans at the same time. In order to keep the bean accessible for their eventual removal, I had to place them in a grain sack, and wrap the edge of the sack around the lid of the keg before closing it. This is keeping the bean suspended, but it is also keeping the lid from being completely air tight. I purged what oxygen was in the keg, but I know the air won't stay pure CO2. Am I running the risk of oxidizing my beer? I did this yesterday, and plan on keeping it going for 2 to 2-1/2 weeks.
