I think the "premium" is what I'm noticing; I kind of ignore all the large packs of aluminum beer cans (though to be honest that's the only beer I have on hand right now).
What I have very rarely seen is plastic beer - only at stadiums where they don't want you throwing the bottle at the players, basically.
Of course, the only proper beer container is a giant keg.
