     What else is the yeast putting off besides CO2?"
     The yeast is generating lots of minor byproducts, including alcohol, 
     but we can ignore those. They're of interest to home-brewers.  I think 
     the difference you see is because the yeast system is pushing a lot of 
     air (which is mostly nitrogen) and this doesn't dissolve readily.  The 
     bottled CO2 is pure and dissolves completely.
