w/in 18mos. you will see a predominant shift of wine into boxes/hermetically sealed, opaque bags. It's far superior and cheaper.
As far as beer in an aluminum bottle, already Danska vodka comes in a similar 'bottle' - assuming they can seal the bottle similarly, you might see it relatively quickly for low-end beers, but there's a lot of homerism for bottled beer (especially among premium craft brews - cans don't sell at all).
PS - Iron City sucks so bad
