When will we see these available at the home-brewer level?
I'm aware of the argument for O2 permeability, but I believe the real reason why they have not entered widespread use by the big breweries is that they bottle pasteurize. And if it takes 2 - 3 years for enough O2 to pass through the membrane of PET to skunk a beer, then this is not really likely to be of any concern to most of us home-brewers.
For some time now reusable 500 ml (16.9 oz.) amber PET beer bottles with 28 mm reusable thread caps have been generally available, but for the US market this is an awkward size. Something closer to 375 ml. would be ideal. 375 ml would allow for a full 12 ounce fill with 20 ml of remaining head-space.
